“…The magnitude of the GCA/SCA variance ratio revealed that all measured traits were under control by the nonadditive gene action across environments. This finding is in agreement with Channa et al (2018) and Dezfouli et al (2019), who found a multitude of non-additive genetic effects in the inheritance of plant height, days to 50% flowering, 1000-seed weight, oil content, and seed yield per plant in canola under a normal condition. However, these results contradict the findings of other studies (Shehzad et al, 2015), reporting that additive gene effects showed to be more important in controlling canola seed yield and oil content.…”

“…In this study, the crosses H2/S × Serw4, H2/S × AD/201, and Topaz × Serw.6 across all environments proved promising specific combiners for improving SOC. Similar findings also came from Channa et al (2018) and Farouk and Arafa (2018). However, the hybrids H2/S × Serw4 and Serw4 × Serw6 were the best specific combiners for more than one trait, such as, DTF, NPB, NP, TSW, SYPP, SOC, ProC, Ca ++ , and K + /Na + .…”

“…It indicates that both additive and non-additive gene actions were essential in controlling the inheritance of these traits under all tested environments. Similarly, significant GCA and SCA effects occurred for multiple attributes in canola (Channa et al, 2018). The magnitude of the GCA/SCA variance ratio revealed that all measured traits were under control by the nonadditive gene action across environments.…”

Creating a half-diallel cross succeeded among seven diverse canola genotypes. The obtained 21 F1 hybrids with their seven parents underwent three salinity stress levels exposure—3.91 dsm1 (Normal), 6.24 dsm-1 (S1), and 7.81 dsm-1 (S2) —during the 2020/2021 growing seasons. Salinity treatments significantly reduced days to 50% flowering, plant height, number of primary branches, pods/plant, 1000-seed weight, seed yield/plant, seed oil content, relative water content, calcium, potassium, and the ratio between K+ and Na+ compared with a normal condition. Proline content, osmotic pressure, and Na+ were considerably higher under salinity stress conditions. Highly significant differences showed among the parents and hybrids for all traits across the tested environments. General (GCA) and specific (SCA) combining ability effects were highly significant for all attributes. The parental genotypes Serw4 and Pactol resulted as good general combiners for increased seed oil content (SOC), seed yield/plant (SYPP), and some of its components in research environments. The hybrid combinations H2/S × Serw4 and Serw4 × Serw6 were good specific combiners for days to first flower (DTF), number of primary branches (NPB), number of pods per plant (NP), a thousand seed weight (TSW), seed yield per plant (SYPP), seed oil content (SOC), proline content (ProC), Ca++, and K+/Na+. The SDS-PAGE analysis of seed proteins indicated high levels of genetic variability and revealed some vital biochemical markers for salt tolerance.

“…Indian mustard being a self pollinated crop, the mating of diallel analysis for combing ability is very useful for screening of suitable lines for any breeding program. F 1 hybrids provide information about the genetic components and inform to the breeders to select a suitable breeding procedure for improvement of population and cultivar development (Channa et al, 2018). The present investigation was undertaken to study combining ability in IC lines of Indian mustard.…”

The present investigation on Indian mustard was comprised of a half diallel set of 5 parents and their 10 crosses. Three cross combinations exhibited positive significant heterobeltiosis for seed yield/plant. On the basis of per se performance and estimates of heterosis, the cross IC-342777 × IC-339953 found to be most promising for seed yield/plant. GCA effects revealed that IC-335858 followed by IC-355856 having significant and positive GCA effects was found to be the best combiner for most of the yield contributing traits and on the basis of SCA, IC-342777 × IC-339953 and IC-342777 × IC-355856 was recorded best specific combination for most of the yield contributing traits. It may be concluded that IC-355856 is a good general combiner and IC-342777 × IC-355856 is a best specific combination for higher yield.
