The effects of inbreeding procedure on developing elite inbred lines of corn (Zea mays L.)


, : The effects of inbreeding procedure on developing elite inbred lines of corn (Zea mays L.). Journal of Sichuan Agricultural University 8(1): 61-70

Four methods were used to produce 32 inbred lines from the local variety Qingshen White and the hybrid Qingshen X Mexican White Synthetic 94. Phenotypic value, general combining ability (GCA) and phenotypic and genetic variances were measured for 14 traits in the inbred lines and their test hybrids. Lines developed by mild inbreeding showed higher vigour, yields and GCA than lines developed by intensive selfing. Variances were not significantly affected.

Progenitors of 3 single maize hybrids were crossed with 23 lines, and donor lines were used for the improvement of the grain yields of AN1 x AN2, SSE232-33-30 x SSE255-18-19 and SSE255-18-19 x M.L.S4-1. Lines per se and the crosses were evaluated...

In a study of 6 inbreds using Method 2, Model, I of Griffing (1956) specific combining ability (SCA) effects (and hence non-additive gene action) predominated for grain yield/plant, grain weight, ear length and plant height. General combining abil...

The most resistant inbred was Iowa B52 and the most consist...
