Abstract

ABSTRACTGenotype x environment interaction always presents in soybean multilocation trials in Indonesia. The objective of the research was to determine the performance of yield and yield components of soybean promising lines in two locations. A total of 11 promising lines, and three check varieties (Tanggamus, Wilis, and Anjasmoro) were evaluated in NTB and DIY in dry season 2013. The design was randomized complete block design with three replications. The results showed that yield and yield components were influenced by locations, genotypes and genotypes x locations interaction, except for days to maturity which was not influenced by the location. Number of filled pods had a significant positive correlation with grain yield of soybean. TGM/Anj-773 line had high average yield at two locations and higher than the check variety (Tanggamus).Keywords: correlation, genotype x environment, Glycine max

Abstract

National demand on soybean can be full filled by extending production area including marginal lands. Tidal swamp is one of marginal lands which potentially can be cultivated for soybean production with the use of tolerant varieties to waterlogging. So far, there are only two varieties that are tolerant to tidal swamp condition. This research was conducted to study the response of soybean genotypes to waterlogging and to provide gene resources in breeding for tidal tolerant variety. The research was conducted from October 2007 to February 2008 in the glasshouse of Indonesian Legume and Tuber Crops Research Institute (ILETRI), Malang. The experimental design was split-plot with two replications; where the main plot was waterlogging treatment and the sub plot was soybean genotype (17 genotypes of ILETRI collection). The results showed that soybean genotypes had different responses to different water treatments, shown on the number of branches and reproductive nodes, the number of filled and unfilled pods, and yield (dry seeds) per plant. Waterlogging inhibited plant growth of all traits. Under waterlogging, the highest number of reproductive nodes and filled pods, and yield per plant was from MLGG 0537 i.e. 12.25, 19.25, and 3.13 g plant-1, respectively.

Abstract

Performance of soybean growth and development is influenced by environmental conditions. On similar soil fertility conditions but different environmental conditions such as rainfall will also lead the changes in the performance of the plant. The research aimed to study the agronomic performance of the potential soybean lines in two different drought acid land agroecologies. The experiment was conducted at the South Lampung Tegineneng experimental station and East Lampung Taman Bogo experimental station from February until May 2013. The South Lampung Tegineneng experimental station has a pH of 5.50 and an average rainfall of 89 mm per month, and The East Lampung Taman Bogo experimental station has a pH of 5.12 and an average rainfall of 213 mm per month. The experiment consisted of 10 soybean lines adapted acid land and two check varieties. The experiment was arranged in randomized completely block design with four replications. The least significant different test (LSD) at α = 0.05 was used to calculate significant differences among all treatments. The results showed that rainfall influenced agronomic performance of soybean more than soil acidity. The yield performance in South Lampung was lower than in the East Lampung. Four genotypes produced higher grain yield than the Tanggamus variety in both locations, i.e. Tgm/Anj-862, Tgm/Anj-784, Tgm/Anj-888 Tgm/Anj-857, and Tgm/Anj-858. Tgm/Anj-862 was the most superior genotypes for having the highest number of branches, number of pods, and 100-seeds weight and seed yield and consistent at both locations. The four genotypes, especially Tgm/Anj-862, were potential to be developed in both locations or other locations with similar environmental conditions.Keywords: grain yield, ultisol, yield components
