Abstract

[VEGETATIVE AND REPRODUCTIVE PERFORMANCES OF MAIZE HYBRIDS GENERATED FROM INBRED MUTANTS (M4) ON DARMAGA LATOSOL]. The development of hybrids from local germplasms are extensively done as alternative to the expensive imported hybrid seeds. The farthest genetic distance of parental lines is required to develop the best hybrids. The objective of this study was to compare the vegetative and reproductive performances of hybrids generated from crosses of M4 inbred lines, generated from the selected gamma irradiated mutants. Twenty eight hybrids derived from diallel crosses of M4 inbred lines and a check hybrid variety (NK33) were evaluated on Darmaga latosol. The results showed that all hybrids had lower performances on vegetative and reproductive characters compared to NK33. However, based on the selection index involving all characters, hybrids of G3 x G8, G6 x G8, and G8 x G6  with the index values of   9.45, 7.85, and 6.72, respectively,  performed better than or similar to  NK33.

Abstract

A comprehensive assessment of genetic diversity offers invaluable insights to breeders. This study aims to analyze the genetic diversity of 19 cayenne pepper genotypes using morphological and SSR markers.  Morphological markers are essential for evaluating visible traits while SSR markers provide deeper insights into genetic variation. Using both morphological and SSR markers provides a more robust, multidimensional approach to understanding genetic diversity. Morphological characterization was conducted on 19 bird pepper genotypes using 30 distinct traits, further divided into 95 sub-traits, to evaluate vegetative and generative growths. Molecular profiling was carried out using 10 SSR primers. The SSR analysis yielded 80 scorable bands, of which 72 were polymorphic. The high polymorphic information content suggests that these markers were effective in differentiating the genotypes.   The genetic diversity within the population was substantially high, providing valuable genetic material for breeding programs. Genetic similarity analysis divided the population into six distinct groups. Among them, Group I (genotype A05 Taiwan) and Group VI (genotype A02, Bengkulu Indonesia) formed unique, solitary groups, distinguishing them from other clusters. This information is highly beneficial for bird pepper cultivar development, emphasizing the importance of incorporating additional traits to align with the cultivar development of high yielding and saline-stress tolerance.

Abstract

Bengkulu province area elevating from 0 m to over 1000 m above sea level possesses high rice germplasm diversity. To obtain salinity controlling gene(s) from those germplasm, it is required to determine a suitableprotocol. This research was objected to determine NaCl concentration to select Bengkulu rice landraces. The standard most salinity tolerant genotype used in this research was ’Kuning’, a local variety usually grown on tidal area of Seluma Regency for generations. The growing media was Yoshida nutrient culture supplemented with a series of NaCl concentration of 0, 2000, 4000, 6000, 8000 or 10000 ppm. Observation was done every 2 days to find out the response pattern of rice seedling growth on different NaCl concentration. NaCl stress level was determined at 90% seedling dead (LC90) at the eighth day. The results showed that the increase of plantheight was deceased at concentration of 6000 ppm. Based on the mathematical equation generated from the percent mortality data distribution, the LC90 was at 3910 ppm NaCl concentration.

Abstract

One major problem of low mungbean production in Indonesia is the lack of high yielding varieties for marginal land. A study was done with an objective to compare growth and yield of twelve mung bean genotypes on ultisol fertilized with several doses of cow manure. Twelve mung bean genotypes were grown in a field under a randomized complete block design arranged in a Split Plot Design with 3 replications. The Main Plots were four doses of cow manure, i.e. 0, 3, 6 or 9 ton.ha-1 and the Sub-Plots were twelve mungbean genotypes, i.e. VR 3, VR 61, VR 88, VR 200, VR 204 K, VR 213 K, VR 266 ct, VR 341, VR 368, VR 601 m, VR 222 Walet and VR 1074 Vinna-1. The result showed that the interaction between cow manure doses and mungbean genotypes was only occured on number of leaf. Genotype VR 61 demonstrated the highest plant stature, the greatest pod number, the heafiest pod and seeds per plant. Increasing dose of cow manure until 9 tons.ha-1did not reach the optimum level for the growth and yield of mungbean genotypes yet, except on the number of leaf variable on genotype VR 3, VR 88, VR 200, VR 266 ct and VR 601.

Abstract

Bacterial wilt (Ralstonia solanacearum) is the most important tomato diseases which can reduce tomato yield up to 100%. One most prospective control measure is the development of high yielding varieties tolerance to bacterial wilt. Donor parent carrying bacterial wilt controlling gene(s) is required to develop such varieties. The objectives of this study were to screen thirty-seven tomato genotypes for tolerance to R. solanacearum and to obtain RAPD markers of resistance to bacterial wilt. The experiment was arranged without the experimental design. Each tomato genotypes consisting of 5 control uninoculated plants and 10 plants were inoculated with R. solanacearum with a concentration of 106 cfu / ml inoculum of 10 mL per plant. Scoring was done on the severity of disease symptom; and the plants were grouped according to scoring class. Molecular analysis was done by using Bulk Segregant Analysis (BSA). The results showed there were six genotypes considerd very tolerant i.e. genotype Pearl, Opal, Cung, Syu and Kudamati I; tolerant genotypes consisting of five genotypes; medium tolerant groups consisting of eight genotypes; medium sensitives groups consisting of 14 genotypes; and sensitive class consisting of four genotypes, namely Aceh Local Tomatoes I, Tanah Datar Local Tomato, Tomato Meranti I and Tomato Meranti II. Of the 20 primers used only 8 primers showed visible DNA bands, they were E1, E7, E10, H2, H5, H13, H16 and H19. However there no polymorphics bands observed for bacterial wilt tolerance.

Abstract

Indonesia needs to develop high yielding wheat varieties adapted to tropical highland environment, through benefit selection in order to reduce grain imports. Pretiminary studies are often conducted to support the selection of activities to determine whether there is a closeness connection or relationship between variables with other variables through correlation studies. This study aims to determine the level of closeness between vegetative and generative variables and results in each 18 genotypes of wheat grown in the highlands. This study used a randomized complete block design with 3 replications. The treatments are 18 wheat genotypes : M1, M2, M3, M4, M5, M6, M7, M8, M9, SO 3, SO-8, SO- 9, JARISSA, SELAYAR, NIAS, DEWATA, SO-10, SO-6. Results showed that, plant height and number of seeds per panicle were positively correlated closely with yield of grain weight per clump.  Plant height of JARISSA and NIAS, and the number of seeds/panicle of M2, M3, M7, JARISSA and NIAS.  So that, variable can be used as selection criteria for potential high wheat genotypes grown at higher altitudes in tropical conditions, when the power of inheritance have predictive value (heritability) high. Therefore, these characters can be used as selection criteria for high yielding wheat genotypes.
