Rank correlation between estimated breeding values of egg production traits being 0.73, 0.62 and 0.79 (P≤0.01) between EW and each of DEP and DEM, and between DEP and DEM, respectively. Intracrossed (homogamic) kernels from the ears having the lowest degree of intercrossing (heterogamic) were saved for planting the next generation. It is concluded from a review of the literature that plant cell culture itself generates genetic variability (somaclonal variation). The exotic varieties are (Karashanky a variety introduced from Russian and C.B. Plant breeding is a critical tool in the fight for food security and responsible environmental stewardship in the 21st century. b. The cross (P 1 × P 4) in F 1 hybrid was the highest cross and the cross (P 2 × P 4) in F 2 generation was the highest crosses for this trait. The other crosses exhibited desirable but non-significant standard heterosis for fruit yield and other component traits suggested that there is no scope of exploiting heterosis commercially, but possibility of isolating desirable segregants among these hybrid combinations.
