“…Furthermore, a correlation between F1 mean and SCA r(F1, SCA) also exhibited significant correlation for only lysine content. These results were in agreement with [35][36][37] that emphasized the higher efficiency of SCAs for predicting the grain yield of QPM maize hybrids. Heritability(bs) all traits exhibited more than 90% heritability except shelling percentage.…”

Maize (Zea mays L.) is among the top ten most valuable crops and livestock products. Maize demand and production are continuously rising. The nutritionally rich quality proteins maize (QPM) has almost two times as much lysine as well as tryptophan, amino acids which then the conventional maize varieties. In this study, genetics of important traits in quality protein maize were determined using a Line by Tester matting design. The 45 hybrids were obtained via Line by Tester crossing of 15 lines and 3 testers. The parents and their hybrids were evaluated under two environments. A significant amount of variation was recorded for most of the traits studied. Parental genotypes L2, L6, T2, L8, L7 and L14, exhibited negative and considerable general combining ability (GCA) effects for days to flowering and maturity. L7 × T2, L13 × T3, L10 × T1, L1 × T1, L9 × T2, L5 × T1, L12 × T2, L11 × T3, L10 × T3, L14 × T1 and L6 × T1 were identified with suitable yield and component traits. Crosses L5 × T1, L3 × T1, L12 × T2, L7 × T3, L1 × T2 and L13 × T1 were identified for quality traits. Heterosis over the mid parent crosses L13 × T1 showed highest negative and significant followed by L6 × T1, L12 × T2, L14 × T2 and L2 × T1 for days to 50 per cent tasselling. A significant correlation for the lysine content was determined between F1 mean and specific combining ability (SCA) effects. Overall, this work provides the useful insights into the genetics of important agronomical and biochemical traits of quality protein maize.

“…Likewise, from the last few years, farmer's interest and preference towards hybrids of eggplant have increased dramatically. Moreover, to overcome yield targets and to fulfil the demand, the researchers are focusing on delivering high yielding eggplant hybrids [4,5]. Heterosis is a phenomenon in which a progeny of distinct individuals exhibitshigher/lower values for the traits than the average of any of the original parent used for the development of the hybrid [6].…”

Heterosis (or hybrid vigor) results in a hybrid’s phenotypic superiority over its founder parents for quantitative and qualitative traits. Hybrid vigor is defined by mechanisms such as dominant complementation, over-dominance, and epistasis. Eggplant (Solanum melongena L.) is an essential vegetable crop and a good source of dietary minerals, vitamins, and anthocyanins, with a high oxygen radical absorbance capacity and low caloric value. Given the economic and nutritional significance of eggplants, breeding efforts focus on developing high-yielding varieties—mostly F1 hybrids—with important traits. Studies indicate the successful exploitation of heterosis in the eggplant for a considerable improvement with respect to quantitative traits. In this direction, estimating heterosis for yield-related traits could well be useful for examining the most beneficial hybrid mix with the exploitation of top-quality hybrid. This review examines the current perception of the breeding and molecular aspects of heterosis in eggplants and cites several studies describing the mechanisms. Rendering and combining recent genomics, epigenetic, proteomic, and metabolomics studies present new prospects towards the understanding of the regulatory events of heterosis involved in the evolution and the domestication of the eggplant ideotype.

Chilli pepper is commercially cultivated as a spice and is also used for the extraction of a colouring agent. Here, we performed a diallel genetic study involving five chilli pepper varieties. Parents and their hybrid were evaluated for fifteen morphological and five biochemical traits over two crop seasons under open field conditions. Variation was recorded for all of the studied traits. Similarly, significant values for general combining ability (GCA) and specific combining ability (SCA) variance were obtained for all of the traits. The ratio of σ 2 SCA/σ 2 GCA indicates that non-additive gene effects were predominant for all the studied traits except for fruits plant −1 . Based on SCA effects, cross combinations P2 × P5, and P4 × P5 were determined excellent for flesh thickness, yield components and vitamin C. These hybrids are recommended for multilocation testing to assess their suitability for commercial cultivation. Overall, this work presents useful information regarding the genetics of important morphological and biochemical traits in chilli pepper.
