Abstract

Six genetical populations of early cauliflower (P, P, F, F, BCand BC) developed by crossing different advanced breeding lines and varieties (IIHR-223, IIHR-302, IIHR-217-1-4-6-12, IIHR-73-24, IIHR-Sel-5 and First Early) were studied for estimation of gene effects for ten quantitative parameters, namely days taken for 50% curd initiation, days taken for 50% curd maturity, total plant weight, leaf number, leaf weight, stalk length, stalk weight, curd diameter, curd size, curd yield per plant.The results indicated that all the parameters studied were governed by dominant gene action and thus heterosis breeding can be employed for the improvement of these parameters in early cauliflower.
