Online published on 23 May, 2013. Abstract The experiment was carried out using diallel analysis excluding reciprocal comprised seven parents and their 21 straight F1 hybrids, the material was grown in randomized block design with these replication during rabi at main Castor and Mustard Research Station Saradarkrushinagar (Gujarat). The ratio of gca to sca genetic variance for various characters indicated that, additive type of gene action was predominant for expressing traits like earliness, plant height, Length of silique, seed per silique and oil content The parent IC 385682 manifested good general combines for length of silique, 1000-seed weight and oil content. While SKM 0820 depicted good general combines for seed yield and oil content. Parent RGN 145 good general combines for seed per silique and seed yield. The cross combination IC 385682 x NDR 5-1, SKM 0820 x NDR 5-1, and NDCC28 x NDR 5-1 were found positive and significant sca effects for seed yield per plant. These combination for seed yield had involved AxP, GxP and AxG combiner. Additive and Non-additive type of gene effects, which is flexible in nature. Hence cross are expected through transgressive segregating with later generation. Top Keywords Combining ability, GCA, SCA, diallel analysis. Top |
