CHARACTER ASSOCIATIONS FOR YIELD AND ITS COMPONENTS IN GRASSPEA (LATHYRUS SATIVUS L.) UNDER DIFFERENT BREEDING METHODS

Published on

Two crosses of grasspea, viz., RED x P 28 and RED x EC 242692 were advanced
through single seed descent, random bulk and pedigree methods to assess the nature
of character associations for yield and its components in F4 and Fs generations
under these three breeding methods. Single seed descent method showed a higher
number of significant correlation as compared to random bulk and pedigree methods.
Correlation only between pods per plant and yield per plant was consistent over
breeding methods and generations. The inconsistency of other correlations over
breeding methods and generations may be due to differential changes in gene and
genotypic frequency associated with different breeding methods and genotype x
environment interaction, respectively.
