Abstract

Plant loss during SSD scheme was studied In segregating (F2 to F5) generations
of four cowpea crosses viz., Pusa Phalgunl x V269, GC 1 x RC 8, GC 2 x V 16
and GC 2 x V 240. There was drastic reduction In the population size from F2
to F5 primarily due to poor germination and barren plants due to diseases. The
highest plant loss was observed In F5 of GC 1 x RC 8 (51.17%) followed by F2
of the same cross (27.86%) and in F4 of GC2 xV 240 (25.04%). The plant loss
did not seem to be related to generation but depends on the experimental
material and the condition of the experiment.
