Yield performance of eight mungbean (Phaseolus radiatus) genotypes in two locations in Manggarai District, East Nusa Tenggara, Indonesia. Trop Drylands 1:  24-31. Mungbean [Phaseolus radiatus (L.) Wilczek] is among most important crops cultivated in arid and semi-arid regions. Yet, various genotypes of mungbean are available which might differ in yield productivity across locations. The objective of this study was to elucidate yield performance of eight mungbean genotypes at two locations representing different altitudes (i.e. Murai and  Watu Baur) in Manggarai District, East Nusa Tenggara Province, Indonesia. A Randomized Block Design was employed consisting of 8 treatments, each with 3 replicates. The assigned treatments were eight mungbean genotypes consisting of one local cultivar and seven Indonesian released superior varieties. Observed variables included yield components and yield of mungbean. Data from each location was subjected 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 yield components 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). 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.
