ABSTRACT

Among twenty eight F1s studied, twenty F1s exhibited significant positive heterosis over better parent. The F1, TPT-4 x K-1375 expressed the highest significant positive relative heterosis (41.73%) and  heterobeltiosis  (35.09%) with moderate inbreeding depression (11.39%) indicating the presence of additive gene action for the expression of plant height. For number of primary branches per plant, the F1, ICGV-91114 x K-1375 recorded the highest significant positive heterosis over mid-parent (41.68%), heterobeltiosis (22.48%) and standard heterosis (40.35%) with the highest (22.22%) inbreeding depression indicating the chances of getting desirable genotypes through selection from the further segregating generations of this cross.  The F1, ICGV-91114 x K-1375 recorded the highest relative heterosis (469.23%) and heterobeltiosis (428.57%) coupled with high positive inbreeding depression for number of secondary branches per plant indicating the preponderance of additive gene action in the inheritance of this trait.
