HETEROSIS FOR SEED YIELD AND ITS COMPONENTS, IN CASTOR HYBRIDS
1Gujarat Agricultural University, Sardar Krushinagar - 385 506, India
ABSTRACT
The heterosis over better parent (BP) and standard hybrid (SH) for seed vield per plant ranged from -67.78 to 87.89 per cent and -64.79 to 107.04 Per cent, respectively. The cross combinations SKP 93 x J 1 (87.89 and 107.04%), SKP 93 x 6-219-22 (84.82 and 88.35%) and VP 1 x HO (80.48 and 94.80%) exhibited significant and high positive heterosis over BP and SH for seed yield per plant. These crosses also had significant and positive heterosis for number of capsules plant, number of capsules per main spike and seed yield per main spike and therefore, more desirable for plant breeders to exploit for improving the seed yield of castor
