Heterosis study in vegetable cowpea [Vigna unguiculata (L.) Walp.].

摘要

The present investigation on diallel analysis was conducted in cowpea to study the magnitude of heterosis in cowpea for 14 plant characters including green pod yield and its component characters. The experimental material comprised eight genetically diverse parental lines and their 28 hybrids (excluding reciprocals). Significant standard heterosis and high per se performance with regards to green pod yield and its components were recorded by GC-0203 x Anand Cowpea-1 (21.72% and 111.17 g), Subhra x GC-4 (8.83% and 99.40 g), GC-0203 x GC-0502 (5.26% and 96.13 g) and GC-0502 x Pusa Komal (5.04% and 95.93 g) in positive direction.
