FAZLI DAYIM SHEHZAD AND FARHATULLAH*
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%)
