GRAIN DENSITY AS SELECTION CRITERION IN CHICKPEA AND WHEAT

Published on

The present work using 177 chickpea genotypes consisting of 97 desi, 55 kabuli
and 25 green seeded and 50 wheat genotypes showed that grain density is an
important indicator for post-anthesis source-sink relationship detennining the grain
weight component of yield. The results showed that a wide range of variability
existed for grain weight, volume and density in both chickpea and wheat. Among
the chickpea genotypes, kabuli types exhibited highest range and mean for grain
weight and density. The study on wheat under two environments shows that the
grain density could be increued with simultaneous increase in grain weight and
yield even under abiotic streu environments. It is therefore suggested that the grain
density could be used u a selection criterion u well u a parameter for identifying
tolerence during pain filling particularly under adverse abiotic conditions like late
planting, high! low temperature and moisture stress.
