Combining ability and heterosis for pod yield and its related horticultural traits in garden pea (Pisum sativum L.) under mid-hill sub-temperate and high-hill dry-temperate conditions of Himachal Prad

Published on

A line x tester analysis involving 10 promising lines and
2 testers having wider genetic base were carried out for
pod yield and related horticultural traits in garden pea
(Pisum sativum L.) in diverse environments at Kukumseri
(dry-temperate) and Palampur (sub-temperate) during
summer 2004 and winter 2004-05, respectively. Among
the parents, Green Pearl, Azad P 1, DPP 9418-06 and
DPP 9411 were observed as good general combiners for
pod yield/plant and majority of the component traits. The
cross combinations Green Pearl x DPP 9411 and Azad P
1 x Sugar Giant showed high heterosis and
sea effects
for pod yield and related horticultural traits. The cross
Green Pearl x Sugar Giant was the most promising for
early flowering and green pod picking. For powdery mildew
incidence, the cross VRPMR 10 x Sugar Giant where both
parents revealed high negative
gea effects also showed
significant negative
sea effect and heterosis. For most of
the traits including pod yield/plant, both additive and
non-additive gene actions were of prime importance
