This study aimed to determine the efficacy of several varieties of maize at various rate of manure under drought condition on the dry land of North Lombok. The experiments were designed using split plot design, with manure rates (0, 5, 10, 15 and 20 t.ha-1) as the main plots, and five different maize varieties (P4IS, Gumarang, Lamuru, Sukmaraga and NK212 Hybrid) as subplots. The efficacy of several maize varieties were determined from the weight of dry seeds per plant. Experimental data were analyzed using analysis of variance (ANOVA) at 5 percent significant levels. The mean of each treatments was further tested using the Honestly Significant Difference (HSD) at the same level. The results showed that the highest yield of maize crop was obtained on Lamuru variety at rate of manure of 20 t/ha, ie 85.94 g.plant-1 or 6.14 t.ha-1. The yield of Lamuru variety is similar to that of Sukmaraga, but it is higher compared to P4IS, Gumarang and Hybrid of NK212.The highest yield of maize crop was obtained at rate of manureof 20t.ha-1.

The objective of the research is to investigate the selection response indirectly on the corn yield in dry land, and the yield improvements of yield due to seven cycles. The selection method used were mass selection with and without pollination controll. The method used to minimize environmental effect during selection was subdivided block that (subselection block divided into small plots). In each plot, there was 40 plants, and the number plants selected were 5 %. Randomized Completely Block Design was used to study the selection result. The data collected were analyzed using Analysis of Variance, and the difference between populations were tested using Least Significant Difference in 5 % significant level. The average of selection response per cycle every technique used was gained from polynomial regression coefficient among the characters observed with selection cycle The percentage of the corn yield improvement was gained from the difference between the seventh cycle and the base population, and then, substracted by the base population. The result showed that the response indirectly of mass selection with and without pollination controll were significantly linear, and the values were 47.88 and 72.80 g per plot, respectively. The yield improvements were 43.46 % and 79.21 %, respectively

This study aimed to determine the change in total genetic diversity after eight cycles of mass selection using a technique of selection index for yield, fresh dry matter, and weight of dry harvested cob, and to find out the average of these three characters compared to the initial population. This experiment was carried out at Pringgabaya District, East Lombok Regency using Randomized Block Design (RBD) with 11 treatments, namely eight selected populations, initial populations and two hybrid varieties. Each treatment was replicated 3 times, resulted in 33 experimental units. Data obtained were analyzed using analysis of variance at 0.05 levels. Variance of phenotype is obtained from the variety of samples; while the environmental variance is defined as the average variance of the two hybrid phenotypes. Genetic diversity is obtained from the variety of phenotypes of each population minus the environmental diversity. F-test of 0.05 was performed to find out whether the genetic diversity of the eighth cycle population is the same or different to that of the genetic diversity of the initial population. The average between the initial population and the eighth cycle population was tested using the HSD-test at 0.05 levels. The results showed that the total genetic variation in the population from the eighth cycle selection for yield, harvested dry weight of cobs, and fresh dry matter of maize were smaller than the genetic diversity of the initial population. The average yield, harvested dry cob weight and fresh dry matter weight of population of the eighth cycle selection are higher than the initial population

This study aims to determine the average leaf angle, harvest age and yield of F1 from cross-hybrid composite; heterosis value and knowing the maternal effect of these three traits on maize. The experiment was carried out in technically irrigated rice fields from November 2019 to February 2020. The design used in this experiment was a randomized block design with two replications. The treatment was 28 F1 as a result of crossing P8IS vs NK212 and P8IS vs NK7328 and their respective reciprocal crosses. The experimental data were analyzed by means of analysis of variance and further tested with the LSD test at the 5 percent level. Heterosis values were calculated on the basis of the parents whose scores were higher (High Parent Heterosis). The t test at the 5% level was used to determine whether the maternal effect was significant. The results showed that the mean leaf angles of F1 lines from crosses and reciprocal P8IS vs NK212 were the same as the two parents; whereas the P8IS vs NK7328 cross is different. The reciprocal of cross number 13 (P8IS vs Nk7328 /R13) has smaller leaf angle than P8IS and is the same as the leaf angle of NK7328. The yield of the F1 lines from the two types of crosses was the same as each of the two parents; however, there was a tendency for an increase in yield compared to P8IS for most of the F1 lines. There was a change in leaf angle properties, harvest age and yield of F1 lines compared to one of the best parents with heterosis values are negative and positive with variations from 0.00 to 65.70 percent. Coefficient of correlation between heterosis with the average value of traits was classified as strong for the harvest age; moderate for yield and weak for leaf angle. These three traits in the two types of crosses showed no maternal effects. Smaller leaf angle, super early harvest age and higher yield, are possible to be obtained from the lines of both crosses.

This study was aimed to determine the average of leaf angle, yield and harvest age of each F2 line compared to the two parents respectively. In addition, we also want to evaluate the coefficient of genetic diversity and heritability of the three traits. The experiment was designed in a randomized block design with a total treatment of 20 populations, namely 16 F2 lines and 4 parents. Each treatment was repeated 3 times, so that 60 experimental units were obtained. The experimental data were analyzed by analysis of variance at the 5 percent significance level and further tests using the Least Significant Difference at the same significance level. The results showed that the F2 P8IS x T1NK7328 (R16), F2 P8IS x T1NK7328 (R18) lines, and the F2 P8IS x NK212 (R4) lines, had leaf angles same as each parent of the first hybrid/hybrid offspring (T1NK7328 and NK212) and smaller than the Sinta Unram. The harvest time of the three F2 lines was classified as super early. Yield (weight of dry seeds per plot) of F2 P8IS x T1NK7328 (R16), F2 P8IS x T1NK7328 (R18) lines, were the same as both parents and F2 P8IS x NK212 (R4) lines, higher than Sinta Unram; but the same as the hybrid parent (NK212). Coefficient of genetic diversity of yield is high; medium for harvest time and low for leaf angle. Heritability in broad sense is classified as high, obtained at harvest time and yield; while the heritability of leaf angle is low. The three F2 lines can be used as basic population material for subsequent breeding activities. Key words: hybridization; Sinta Unram; yield; leaf angle

The aim of this study was to obtain superior lines that had higher yields and shorter harvesting ages than their parents. The research was conducted in Saribaye Village, Lingsar, West Lombok Districts, from February to July 2020. The study used a Single Plant Design with the treatment of the M1 G16 mutant population at irradiation doses of 200 Gy, 300 Gy, 400 Gy and 500 Gy and parent (G16 line) as a control. Each treatment planted 200 seeds while the control was repeated three times. The variables observed included the number of productive tillers (saplings), panicle length (cm), number of filled and empty grains per panicle (grains), age of harvest (HSS), weight of 100 grains (g) and weight of filled grain per clump (g). . The value of genetic variance is calculated based on the reduction of phenotype variance with environmental variation (Mangoendidjojo, 2007). Determination of the potential for superior line candidates is done by setting the selection limit value (Xs) according to Kuswanto and Waluyo (2012). The selected genotype is a genotype that has a production value of more than Xs and an age of less than Xs. The results showed that there was an increase in genetic variance due to gamma ray irradiation treatment. A total of three mutant genotypes were successfully selected as candidates for superior strains, namely M1G16-9D3, M1G16-14D3, M1G16-27D3. The three mutant genotypes have the opportunity to be further developed into superior varieties with high yield potential and early maturity.

This study aims to determine the yield potential of several third-generation (M3) black rice mutant strains resulting from mutation induction. The experiment was conducted in a paddy field located in Saribaye Village, Lingsar District, West Lombok Regency, West Nusa Tenggara, from March to November 2022. The experimental design used was a Randomized Block Design (RBD) with nine rice genotypes as treatments, repeated three times. These consisted of seven mutant strains of black rice and two controls, namely the Baas Selem and Inpago Unram varieties. The data were analyzed using Analysis of Variance at a significance level of 5%. In case of significant differences among treatments, further analysis was conducted using the Duncan Multiple Range Test (DMRT) at a significance level of 5%. Based on the research findings, two genotypes of third-generation black rice mutants (M3) resulting from mutation induction were identified. These genotypes, namely D3G46(13) with a yield potential of 5.64 tons/ha and D3G62(19) with a yield potential of 5.84 tons/ha, exhibited higher yield potential compared to their parental strains. However, both of these genotypes have not yet achieved or surpassed the yield potential of the control treatment, which is the Inpago Unram with a yield potential of 8.17 tons/ha.

This research aims to determine genetic diversity, broad heritability and genotypic correlation of several quantitative characters of the S3 line of corn plants in dry land. Treatment of 30 S3 lines, arranged in a randomized block design, two replications. The characters observed included the variables of flowering, growth, yield components, yield and maturity. The observation data were analyzed using analysis of variance at 5 percent significant level, then genetic variance, phenotypic variance, heritability and genetic diversity coefficient were calculated. Genotypic correlation analysis was also carried out in this study. The results show that ASI and yield have wide genetic diversity; while cobs dry weight per plant is classified as medium and other characteristics are classified as narrow. Heritability in a broad sense is relatively high, obtained at silking time, harvesting time and yield. Eight other characters have moderate heritability and the rest have narrow heritability. A high negative genotypic correlation with leaf angle was obtained for leaf area; while the other four characters have a low negative correlation. Harvesting time had a low positive correlation with flowering variables; other characters are not correlated. Yield was highly positively correlated with plant height; while cob length, cob diameter and cob weight were moderately positively correlated. Plants selected for selfing in the next generation are taller plants, with more leaves and earlier silking time.

This study aims to determine the appearance of quantitative characters and kinship relationships of the genotype of red rice and black rice grown in gogo. The research was conducted in February â€“ May 2024 on a medium plain land with an altitude of 370 meters above sea level, in Tampak Siring Village, Central Lombok, NTB. The materials used were 21 rice genotypes consisting of 11 red rice strains, 4 black rice strains, 2 red rice elders, 2 black rice elders and 2 comparison varieties (Inpago Unram I and IR64). The analysis used is the Analysis of Variance (ANOVA) of the Group Random Design (GRD) model with a real level of 5%, if there are real different characters, then the Duncan Multiple Range Test (DMRT) will be continued at a real level of 5%. Cluster analysis was carried out based on the average value of quantitative characters using the euclidean distance method using the R-Studio program. The results of the study showed that between strains all characters had different appearances except for the number of non-productive saplings. G-2 strain; G-6; and G-18 had the same results as Inpago Unram I. Kinship analysis conducted based on the average value of quantitative characters obtained four clusters, namely cluster I G-21, G-9, G-20, G-11, G-17; cluster II G-19, G-2, G-18, G-6, G-7; cluster III G-1, G-5, G-8, G10, G-3, G-4, G-16; and cluster IV G-12, G-15, G-13, G-14.
