dc.description.abstractThe present investigation was carried out with six generations (P1, P2, F1, F2, BC1 and BC2) obtained from three crosses viz. Bhavya x GT 5, Bhavya x A 119 and A 119 x GT 5. The experiment was conducted at the BTRS farm, Gujarat Agricultural University, Anand in compact family block design during kharif 1996-97. Gene effect, Heterosis, heterobeltiosis and inbreeding depression as well as mechanism of nematode resistance were studied. Significant differences among the progenies for yield and its contributing characters were observed, except days to maturity, plant height, days to flower, in all the crosses, leaf breadth and leaf thickness in crossI, number of leaves per plant in cross II and numbers of leaves per plant , leaf thickness, spangle score and nicotine content in cross III. Scaling tests indicated that additive dominant model was fit for all the characters except nicotine content in cross II and nematode index in cross I and II.en_US
