Abstract

Abstract. Mau YS, Madu1VFY, Ndiwa ASS, Adar D, Gandut YRY. 2017 District, East Nusa Tenggara,. The objective of this study was to elucidate yield performance of eight mungbean genotypes at two locations in Manggarai District, East Nusa Tenggara Province. A Randomized Block Design was employed consisting of 8 treatments, each was 3 replicates. The assigned treatments were eight mungbean genotypes consisted of one local cultivar and seven Indonesian released superior varieties. Observed variables included yield components and yield of mungbean. Data from each location was subjectd to ANOVA, followed by a combined ANOVA involving data from both locations. A post hoc test of DMRT (5%) was performed to compare the treatment means. The study results showed that genotype x location interaction significantly or highly significantly affected most of the observed variables, except plant height at flowering, plant height at harvest, productive branches plant -1 and 100-seed weight. Vima-1 and Murai were found to perform better than other genotypes in most of yield component and yield traits in both locations. The highest mean seed yield over two locations was produced by Murai (991.87 g plot -1 ) and Vima-1 (967.90 g plot -1 . Yield performance of eight mungbean (Phaseolus radiatus) genotypes in two locations in Manggarai). Mean seed yield of all genotypes at Perak was 365.0 g plot -1 while that in Watu Baur was 761.27 g plot -1 .

Adaptation of Grain Legumes to Transient Water Deficit in Timor-Leste

“…Similarly, seed size in improved mungbean genotypes ranged from 5.8-8.0 g in a study undertaken in West Timor of Perak and Watubaur, except for the local cv. Manggarai (3.1 g in Perak and 3.6 g in Watubaur) [25,26]. The drought treatment did not affect 100-seed weight at the Aileu site due to the early rain interruption; however, drought significantly affected seed size at the Hera site.…”

“…Seed production at the Hera site was generally higher than at the Aileu site. At the Hera site, mungbean had the highest seed yield (3.14 t/ha), well above that of the Vima genotype grown in the lowland area of Manggarai, East Nusa Tenggara (2.42 t/ha) [25]. Drought reduced plant growth and development, including yield components.…”

Genotype by environment interaction on phenology and synchronous maturity of mungbean

“…Significance of G×E interaction on mungbean was reported for days to first flowering, days to 80% maturity (Waniale et al, 2014), pod weight per plant (Mau et al, 2017;Waniale et al, 2014), and grain yield per plant (Baraki et al, 2020;Ullah et al, 2012). Waniale et al (2014) and Mau et al (2017) reported different results on the effect of G×E interaction for plant height at harvest and 100-seed weight. The study of G×E interaction on harvest period could benefit mungbean breeding programs to develop short harvest period varieties, as well as to identify suitable environments for obtaining a short harvest period.…”
