The  present  study  was  carried  out  to  determine  the  combining  ability  of  yield and yield components by crossing six diverse maize  inbred lines in a half diallel mating design. Fifteen F1 progenies along with their six parents were planted in randomized complete block design with three replications. GCA to SCA ratios were less than one for plant height, cob diameter, cob length and number of kernels row/cob indicating a preponderance of additive over non additive gene action. The crosses P1×P2, P3×P5 and P5×P6 were exhibited significant and positive SCA effects for yield and cob diameter, number of row/cob and number of grains/cob of yield contributing characters. The parents P1 (IL4), P3 (IL18)and P5 (IL23 were good general combiner for grain yield and yield attributing characters. It can be concluded that these parental lines can be desirable parents for hybrids as well as for inclusion in breeding program, since they may contribute favorable alleles in the synthesis of new varieties.

Abstract Accurate identification of promising parents is crucial for peanut (Arachis hypogaea L.) cultivar development. The objectives of this study were to (1) determine the combining ability for yield and yield components of six genetically diverse peanut cultivars, (2) examine the relationship between F1 diallel analysis predictions and performance in subsequent generations, and (3) determine if parental performance per se could be used to identify desirable parents. Six peanut cultivars were selected to represent a wide range of genetic diversity and intermated using a half-diallel mating design. The cultivars included two Spanish market-types, Dixie Spanish and Spancross; two runner market-types, Southeastern Runner 56–15 and Tifrun; and two Virginia market-types, Virginia Runner G26 and Georgia 119–20. Parents and progenies were field evaluated each year at Tifton, GA. The F2 and F3 generations were tested in 1986 and 1987, respectively. Combining ability analysis showed that general combining ability (GCA) and specific combining ability (SCA) effects were significant (P < 0.05) for all variables measured. Although SCA remained a significant source of variation in the F3 generation, it accounted for a relatively small portion of the total variation. Tifrun had the greatest GCA effects for plot yield, pod weight per plant, seed weight per plant and seed number per plant. GCA estimates from F1 progeny were not effective in predicting performance in subsequent generations. Parental performance per se was highly correlated with performance across cross combinations in the F2 and F3 generations. GCA estimates from F2 and F3 progeny provided little information not available from simply examining parental performance.

Diallel Mating

Abstract Nine morphologically distinct kenaf genotypes were hybridized to produce 36 hybrids following a half diallel mating design. The combining ability and gene action of 15 yield and yield components were assessed in hybrids and their parents across two environments. Except for the mid diameter and plant height traits, there were highly significant differences (p ≤ 0.01) between both the analysis of variance of environments and the interaction of genotype and environment. For the inheritance of these traits, additive gene effects were considerable, and the expression of these additive genes was heavily influenced by the environment. Significant differences were found for all studied traits for GCA except top diameter, and SCA except plant height and top diameter, implying the presence of both additive and non-additive gene action for the inheritance of the concerned characters. For all features except top diameter and number of nodes, the magnitude of GCA variation was significantly higher than that of SCA variance, indicating the additive gene's predominance. The parental lines P1, P3 and P4 were determined to be outstanding general combiners for fibre yield and yield-related parameters. Considering combining ability and genetic analysis study together, the crosses P1 × P4, P1 × P9, P2 × P3, P2 × P5, P4 × P6, P4 × P7, P4 × P9, P5 × P8, and P7 × P9 were found promising for their heterotic response to higher fibre yield, stick yield, seed yield and and could be useful by adopting proper strategies for future improvement in kenaf breeding programmes.
