Abstract

Selfing was carried out on the F2 population of corn plants and the S1 line was produced. Selfing is carried out to form pure lines in order to create hybrids. The aim of the research was to determine the magnitude of inbreeding depression, genetic diversity and heritability of leaf angle trait, yield and harvest age of the S1 line of corn plants under drought stress conditions in dry land. The experiment was carried out from March to June 2023 in Gumantar village, North Lombok district. The design used was a randomized block design, two replications. The number of treatments was 31, namely 30 S1 lines and an F2 population. Plantings are given heavy stress. Observed variables include flowering, growth, harvest age, yield components and yield. The level of inbreeding depression is based on the F2 population and is expressed as a percent. Genetic diversity is calculated based on the results of analysis of variance at a significance level of 5 percent. The results showed that inbreeding depression in leaf angle and harvest age of the S1 lines were relatively low; while the yield is classified as high. Broad categories of genetic diversity were obtained in the yield; while the leaf angle and harvest age are relatively narrow. Broad sense heritability was relatively high in the yield; while the leaf angle is classified as medium and the harvest age is relatively low. The selection of S1 lines should be based on yield, namely lines that have the same yield as the F2 population.

Abstract

The aim of the research was to determine the diversity, distribution, dominance, and yield loss of corn due to competition from broadleaf weeds. Descriptive research method with direct survey techniques of research objects. Data were collected using 10 sample plots measuring 1 m2, which were placed using random sampling. Observation parameters include the population and dry biomass weight of weeds and corn. The data was analyzed descriptively and comparatively by calculating density, frequency, and dominance to obtain an important value index and summation diminance ratio (SDR). The results of the research showed that 14 species of broad-leaved weeds were found with high species diversity, distribution, dominance, and abundance indices. The competitiveness and relative weighted dominance of six weed species, namely Amaranthus spinusus, Amaranthus gracilis, Synedrella nodiliflora, Acalypha indica, Ageratum conyzoides, and Alternanthera philoxeroides, are higher than those of other weed species, causing corn yield losses of 5.56%–21.90%. Therefore, these six weed species must be controlled.

Abstract

The aim of the research is to examine the effect of intercropping corn with leguminous crops on weeds and land use efficiency. The experimental research method was designed using a randomized complete block design (RCBD) with three blocks. The treatments tested were monocrop planting patterns and intercropping between corn and leguminous crops. The results of the research showed that 16 weed species were found with high species diversity, evenness, dominance, and abundance, so that there were six dominant species that existed during plant growth. Peanuts and cowpeas are suitable for intercropping with corn because they can suppress the population and growth of weeds. Soybeans, green beans, and red beans are not suitable because they are not effective in suppressing the population and growth of weeds and compete with corn, so that corn yield losses due to competition are 38.20%–40.96% and due to weed competition, they reach 62.37%–63.77%.  The best ecological and agronomic land use efficiency was obtained by intercropping corn with peanuts and cowpeas, with NKL values based on dry biomass weights of 1.90 and 1.89 (NKL > 1) and dry seed weights of 1.79 and 1.78 (NKL > 1).

Abstract

Increased public interest in red rice and black rice has triggered breeders to develop superior varieties that have high yields and are tolerant of the threat of drought. Genetic parameters are the basis needed for breeding to develop superior varieties. This research aims to examine the genetic parameters of pigmented rice genotypes grown upland. The experiment was carried out in June – September 2024 experimentally in the field using a gogo system, namely in Tampak Siring Village, Batukliang, Central Lombok, NTB. The design used was a Randomized Block Design (RAK) with 21 treatments, 10 red rice lines, 4 black rice lines, 4 parent lines, and 2 comparison varieties. Obtained 63 experimental units by repeating each treatment three times. The data collected was then analyzed using a one-way Analysis of Variance (ANOVA) test with a Randomized Block Design (RAK) model at a confidence level of 95% (α=5%), genetic diversity coefficient (KKG) formula, heritability and genotypic correlation. Referring to the analysis that has been carried out, the findings of the coefficient of genetic diversity and heritability of the number of full grains, weight of 100 grains, yield per plot of red rice and black rice lines are in the high category. The number of productive tillers, weight of 100 grains and weight of grain per hill had a significant positive correlation with the yield per plot, while the number of empty grain parameters had a significant negative correlation with the yield per plot.

Abstract

Selfing is the initial step to form hybrid varieties. Selfing has been carried out for four generations and 29 S4 lines have been obtained. All lines have been tested for their tolerance level to drought stress in dry land. The purpose of the study was to determine the tolerance level of S4 lines of corn plants to drought stress in dry land. Experimental methods with field trials were used for the test. And the correlation between characters and ISC values. The design used was a randomized block design at each stress level. Determination of the tolerance level used the observation parameter of the results (dry seed weight per plant) under mild stress conditions and normal conditions. The tolerance level to drought stress was measured from the Stress Sensitivity Index (ISC) value. The results showed that three S4 lines were tolerant to drought stress, namely lines S4.7, S4.15 and S4.24. Nine S4 lines have moderately tolerant category, namely lines S4.1, S4.3, S4.8, S4.12, S4.13, S4.14, S4.21, S4.26 and S4.29; the rest are classified as sensitive. The yield have a high negative correlation with the ISC value; the weight of dry cobs harvested per plant has a moderate negative correlation. The three tolerant lines can be used for the formation of S5 lines.
