Abstract

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.
