GENETIC DIVERSITY ON THE BASIS OF PHOTOSYNTHETIC AND YIELD RELATED TRAITS IN CHICKPEA (CICER ARIETlNUM L.)

Published on

Genetic diversity was assessed ina collection of 52 tme breeding advanced generationlines
and two check varieties of chickpea on the basis of photosynthetic and yield related traits,
including nodulation parameters to identify physiologically efficient types. The study
revealed enormous diversity in the material as indicated by the wide range of D2 values
from 53.9 (between the genotypes ICCV 90125 and ICCV 90127) to 15054.0 (between the
genotypes ICVV 90103 and ICCV 90113). The genotypes fell in nine clusterswhen grouped
using the Tocher's method. ClusterVhad thehighestnumber ofgenotypes. The intercluster
distances ranged from 339.4 between clusters I and V to 15054.0 between VIII and IX. The
cluster means for different characters were worked out and the future strategies are
discussed after identifying genotypes as potential sources of genes for photosynthetic and
yield related traits.
