Abstract:

Chickpea, a cool season legume crop of the family Leguminosae and of the genus Cicer, is the world’s largest pulse crop. This crop has high productivity and holds prominent position in the international food grain trade. An experiment was conducted to identify the transgressive segregants for yield and yield contributing characters in F2 population of three crosses in chickpea. In most of the tansgressive segregants, in each of the three crosses, better parent yield was transgressed with transgression of one or several other characters. In general, the highest proportion of transgressive segregants were recorded for grain yield per plant (59) followed by number of pods per plant (46), plant height (41), number of seeds per pod (40), 100-seed weight (39), plant spread (38), number of primary branches per plant (38) and number of secondary branches per plant (37). In most of the transgressive segregants, in each of the three crosses, better parent yield was transgressed simultaneously with transgression of one or several other characters. Simultaneous transgression of grain yield per plant in association with plant height, number of primary branches per plant, number of secondary branches per plant, plant spread, number of pods per plant and 100-seed weight was observed more frequently. It was concluded that either grain yield per plant is dependent on this character or there may be linkage drag, so that genes responsible for these characters move together. The most promising transgressive segregants observed in F2 generation were Plant No.44 of Cross 1, Plant No.30 of Cross 2 and Plant No. 27 of Cross 3.
