Genetic analysis of seed growth rate and progress towards flowering in chickpea (Cicer arietinum L.)

Published on

Genetic analysis of seed growth rate (SGR) and progress
towards flowering (RPF) along with yield components was
carried out in chickpea using Hayman's and Griffing's
diallel procedures. Estimates of genetic parameters showed
significant additive and non-additive gene effects in the
inheritance of the traits studied. The additive component
was predominant for RPF, SGR and seed weight, and the
non-additive component was predominant for pods per
plant, seeds per plant, seeds per pod and seed yield.
Estimate of the narrow-sense heritability was high (90%)
for RPF, SGR and seed weight, and low for the remaining
traits. The close association observed between SGR and
seed weight makes it possible to select for higher SGR
through selection for larger seed size. SGR and seed
weight could be used as selection criteria for yield
improvement.
