Combining ability analysis for green pod yield and its components in inter sub-species of cowpea [Vigna unguiculata (L) Walp.] ssp.

Abstract

Six lines, two each from Vigna unguiculata ssp. unguiculata (vegetable type), Vigna unguiculata ssp. unguiculata (grain type) and Vigna unguiculata ssp. sesquipedalis (vegetable type) as female parents and four testers from unguiculata ssp. unguiculata ( three vegetable type and one grain type) as male parents were crossed in line x tester matting design. The ICP-38, ICP- 42, Indira Hari and Arka Garima were good general combiner for earliness and ICP-42, ICP-54, Pusa Komal, Arka Garima and Indira Hari for green pod yield per plant. The cross combinations ICP-42 x Arka Garima, ICP-54 x Indira Hari, ICP-26 x Khalleshwari and ICP- 49 x Khalleshwari were found best for number of pods per plant whereas, crosses ICP-42 x Arka Garima, ICP- 42 x Indira Hari, and ICP-54 x Arka Garima showed high significant and positive sca effects with high mean for green pod yield per plant.
