EFFECTS OF WATER STRESS ON YIELD ATTRIBUTES AND YIELD OF DIFFERENT MUNGBEAN GENOTYPES (Pages : 19 - 24)

A field experiment was conducted at the experimental field of Bangabandhu Shiekh Mujibur Rahman Agricultural University, Gazipur during April to June 2004 to characterize different plant parameters related to yield performance of twenty seven Mungbean (Vigna radiata L.) genotypes under water stress condition. A wide diversity among the genotypes in their physio-morphological characters including yield was recorded. Genotypes varied from 26.67 to 34.0 days to initiate first flower. They differed remarkably in producing seed yield (g/plant) and the difference in yield was attributed due to a great variation in yield attributes. Pods number per plant was highest in GK 37 (29.40) and lowest in GK 27 (8.80). The highest number of seeds per pod was obtained from the genotypes GK 35 (9.52), which was closely followed by GK 30 (9.44), GK 25 (9.27), GK 37 (9.14) and GK 11 (9.00) respectively, while GK 27 (7.39) produced the lowest. The highest seed yield (g /plant) was obtained from GK 37 (10.71g), followed by GK 19 (10.33g) and GK 11 (10.13g). The lowest yielder GK 27 (3.27g) was closely followed by two genotypes, GK 24 (5.87g) and GK 25 (5.92g). Seven genotypes appeared to be intermediate that was about 26% genotypes of the total. The correlation coefficient of variation were high for no. of branches per plant, pods per plant, days to 50% flowering, plant height, seeds per pod as well as seed yield g/plant that indicated a wide variability and better scope for selection.
