HETEROSIS IN RELATION TO COMBINING ABILITY IN BLACK GRAM

Published on

Combining ability analysis on a 9 x 9 diallel cross in black gram revealed that high per se
perfonnance of parents does not necessarily reflect their good general combining ability.
The parents HPU392 and UH 27 were judged as good general combiners for seed yield. The
hybrids UH 45 x UH 27, HPU 392 x UH 22, UH 27 x Pant U 19, HPU 384 x UH 45, and HPU
392 x UH 2 were identified as potential cross combinations on the basis of heterosis and
specific combining ability. The predominance of nonadditive components in the
inheritance of the characters studied was also observed.
  

Keywords: Diallel, combining ability, heterosis, black gram.
