INHERITANCE OF POD WEIGHT IN COWPEA (VIGNA UNGUICULATA (L.) WALP.)

Published on Nov 02, 2019 03:20 AM

The inheritance of pod weight in cowpea was studied using three intraspecific cultigroups
in fields planting of the parents, Fts, F2S and backcrosses to both parents of three crosses:
Assam Local 1 X Birsa Sweta (bifloTa X sesquipedalis), Assam Local 1 X Yard Long Bean
(bifloTa X sesquipedalis) and Pusa dofasli XCheck Barbati (unguiculata X sesquipedalis). Pod
weight was inherited quantitatively. BifloTa X sesquipedalis crosses showed that light pod
partially dominant over heavy pod, while in the unguiculata X sesquipedalis cross mean pod
weight in Ft and F2 was almost equal to the midparental value. Gene action was
predominantly additive, although dominance, additive X additive, additive X dominance
and dominance X dominance gene actions were significant in the bifloTa X sesquipedalis
crosses.
