ABSTRACT

The present investigation comprising of nine parents and 20 cross combinations of pigeonpea (Cajanus cajan (L.) Millsp.) developed through Line X Tester (5 × 4) crossing programme were evaluated for genetic parameters. High GCV and PCV, heritability and genetic advance as per cent mean were observed for the characters viz., secondary branches per plant, pods per plant, harvest index and seed yield per plant both in parents and crosses, indicating these characters are under the control of additive genetic variance.
