SELECTION OF ELITE GENOTYPES FOR YIELD AND ASSOCIATED TRAITS IN F2:3 FAMILIES OF INTERSPECIFIC CROSSES IN BRASSICA SPECIES
Abstract
Interspecific crosses of Brassica species were evaluated to identify desirable genotypes for yield and associated traits. Parent al species included Brassica napus (Dunkled, Maluko, line A-20-20), B. campestris (lines 1203 and 2163), B. carinata (Peela raya), and B. juncea (lines PR-64 and 89111-1). All traits were segregated in F2 population. All parameters were decreased in F3 in comparison to F2 population, indicating higher response of the crosses to inbreeding depression (0-85%). A reduction in height (12-27%), primary branches (18-35%), pods main raceme-1 (19-35%), seed pod-1 (10-31%), pod length (14-28%)
