COMPARISON OF BREEDING METHODS FOR IMPROVEMENT OF YIELD AND ITS COMPONENTS IN GRASSPEA

Published on

Three breeding methods, viz., pedigree, single seed descent and random bulk were
compared for their relative efficiency in terms of change in population mean in F4
over F3 and in Fs over F3 as well as F4 generations for yield and its components in
two crosses of grasspea, namely, RED x P 28 and RED x EC 242692. In general, single
seed descent method proved to be superior to random bulk and pedigree methods
in showing maximum changes in population mean for different characters, whereas
random bulk method showed the worst performance in this regard.
