Abstract

High variability for maturity and its components traits indicating earliness like days to
flower initiation, days to 50% flowering and days to pod initiation was observed in a recombinant
inbred lines (RILs) developed from cross between ICCV 2 and JG-62. Duration of reproductive
period (DRP) was computed based on the difference between physiological maturity and days
to flowering initiation. DRP did not show any correlation with maturity indicating the possibility
of getting varying lines of DRP with a range of maturity levels in a given environment. A critical
length of DRP of 50-60 days was found more ideal with a crop duration of about 90 days as
observed from the study. It is suggested to investigate the DRP for chickpea ecologies with
different characteristic maturity period. Association analysis indicated that DRP influences yield
mainly through pods per plant.
