dc.description.abstract An experiment was carried out at the University of Agriculture, Peshawar during 2012-13 using a set of F1 hybrids of B. carinata for estimating heterosis and heterobeltiosis for important yield and quality parameters. The experimental material comprised of six B. carinata parental genotypes viz. C-88, C-89, C-90, C-93, C-95, C-97 and their 30 F1 hybrids as direct crosses. A randomized complete block design with two replicates was used for field evaluation of 36 B. carinata genotypes (6 parental lines and 30 F1 hybrids). Significant genetic variation was observed for primary branches plant-1, main raceme length, seed yield plant-1, oil and protein content among parents as well as F1 hybrids. The highest heterosis and heterobeltiosis for primary branches (24.25 vs. 12.30%) and main raceme length (37.31 vs. 22.93%) was recorded for F1 hybrids C-88 × C-93 and C-89 × C-97, respectively. Hybrid C-93 × C-90 had the highest positive heterosis for seed yield plant -1 (23.33%). For protein content, the maximum heterosis was recorded for hybrid C-88 × C-89 (11.34%). Similarly, F1 hybrid C-88 × C-97 showed maximum heterosis for oil content (14.41%). The highest heterobeltiosis was exhibited by hybrids C-90 × C-97 for seed yield (9.53%) , C-89 × C-90 for oil content (7.61%) and C-93 × C-97 for protein content (4.11%). Based on high mean performance and heterotic values, aforemntioned hybrids and their corresponding parental lines will be exploited further for commercial hybrid production. en_US
