Induced mutations in mungbean breeding: Regional yield trial of mungbean mutant lines

Comparison of mungbean mutant lines with the standard varieties was conducted at various stations during 1998 and 1999, RCB was employed with 4 replications. In the year 1998, 12 selected mutant lines were planted in 10 experimental plots at 7 locations and the three lines of M5-5, M5-1 and M4-2 wer...

Summary:Comparison of mungbean mutant lines with the standard varieties was conducted at various stations during 1998 and 1999, RCB was employed with 4 replications. In the year 1998, 12 selected mutant lines were planted in 10 experimental plots at 7 locations and the three lines of M5-5, M5-1 and M4-2 were found to give the high yields of 243, 235 and 229 kg/rai, respectively, comparing to 213 and 228 kg/rai of KPS1 and CN36, respectively. During 1999, 12 mutant lines were planted in 6 plots at 5 locations and it was found that M5-10, M4-2, M5-5 and M5-22 gave yields of 240, 240, 236 and 232 kg/rai, respectively, while KPS1 and CN36 gave 227 and 232 kg/rai, respectively. Whereas the highest yield was obtained from M5-5 in 1998, it was M4-2 in 1999. The 2 year-tests resulted in the selection of M5-5, M5-1 and M4-2 for further comparing study with the standard varieties in the farmers' fields.
