ABSTRACT
The 32 cowpea crosses (4 x 8) along with 12 parents were evaluated for 11 yield and its contributing characters to estimate heterosis. Heterosis was observed for all characters studied. Among crosses tested, 25 and 18 crosses depicted significant positive heterosis for grain yield per plant over their mid and better parent values, respectively. It is primarily due to complementary combination of component traits viz., branches per plant, clusters per plant, pods per plant, seeds per pod and 100-seed weight. The cross combination GC-4 x DCP-7 and Pusa Phalguni x DCP-6 found promising from commercial point of view and could be further exploited to get superior segregants. For protein content, hybrid Pusa Phalguni x DCP-7 recorded highest relative heterosis as well as heterobeltiosis.
Key words :
Cowpea, Heterobeltiosis, Heterosis.
