Abstract:
The present investigation was carried out to estimate extent of transgressive segregants for the important yield and yield contributing characters using F₂ generations of two crosses and four backcrosses of cowpea. The experiment was conducted during kharif season 2020-21 at Experimental Farm, Department of Agricultural Botany, College of Agriculture, Latur. The experimental material comprised of three parents, F₂. and backcrosses. Observation were recorded on days to 50% flowering, days to maturity, number of primary branches per plant, plant height (cm), number of pods per plant, pod length (cm), number of seeds per pod, test weight (gm) and grain yield per plant (gm). In this investigation total one hundred and thirty one transgressive individuals with values exceeding the better parent were observed in two crosses for seed yield with two or more yield contributing characters likes’ number of primary branches per plant, plant height, number of pods per plant, pod length, number of seeds per pod, and test weight. Individual transgressing simultaneously for plant height and test weight, seed yield were common compared to other combinations.
