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

Published on

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.
