“…This indicates that the nonadditive (dominance, over dominance and epistasis) effects seem more important than additive effects in these traits' inheritance mechanisms. The preponderance of nonadditive variance in expression of these traits in wheat have also been reported by Dhadhal et al (2006), Lohithaswa et al (2013), Barot et al (2014), Pansuriya et al (2014), Ahmed et al (2017), Ahmed and Mohamed (2009a) and Bajaniya et al (2019) for 100-grain weight; Sharma and Garg (2005), Vanpariya et al (2006), Singh et al (2013), Ahmed and Mohamed (2009a) and Bajaniya et al (2019) for grain yield per plant. Because of these studies, it could be concluded that grain yield is a complex character compared to its components.…”

“…For 1000 grain weight, the best three crosses are viz., AKAW-4627 x AKW-1071, AKAW-4627 x AKAW-4210-6 and K-0307 x HPBW-01 and highest grain yield plant -1 (g) are AKAW-5014 x GW-322, MACS-6222 x HPBW-01, MACS-6222 x WB-2 and AKAW-5017 x AKAW-5014. Similar results are reported by Barot et al (2014) [2] , Baloch et al…”

Combining ability analysis was studied in a twelve parents of bread wheat (Triticum aestivum L.). Which were crossed in a diallel fashion (without reciprocals) and their 66F1's were grown in a field experiment at Wheat Research Unit, Dr. P.D.K.V., Akola during in 2017-18 to study the combining ability for grain yield and its component traits. The gca and sca components of variances were significant for all studied characters. The (gca/sca) variances below unity in the generation showed the predominance of nonadditive gene actions effects for all the traits. On the basis of general combining ability (gca) effect and per se performance, parents AKAW-5014 and AKAW-4924 emerged as good general combiners for grain yield per plant and average to high combiners for almost all the traits under study. Parent AKW-1071 was good general combiner for number of tiller/ plant and parents AKAW-5014 and AKAW-4924 also exhibited positive gca effects for days to 50% flowering, days to maturity, plant height, number of seed/earhead and grain yield. On the basis of sca effects, the crosses AKW-1071 xHPBW-01, AKAW-5017 x AKAW5014, AKAW-4924 x GW-322 and AKAW-5014 x WB-2 emerged as good specific cross combinations for grain yield per plot. Hybridization scheme for wheat improvement, such as multiple crossing or bi-parental mating could be useful in further manipulation of genes for economic purposes.

“…Early maturity is the desired key characteristic in wheat breeding projects that enables plants to avoid terminal stress in drought conditions and produce a reasonable yield (Mondal et al, 2016). Current investigation results are consistent with the assertion that none of the F 1 groups exhibits undesirable and undesirable SCA consequences (Barot et al, 2014). The study also determined that PR128 was a superior general combiner and needs usage in wheat breeding projects for early maturity.…”

The knowledge of genetic variability, combining capability, and gene activity are vital in enhancing wheat productivity. Six diverse wheat genotypes, Anmol91, Fatehjung16, Khattakwal, Auqab2000, PR128, Abaseen 2021, and KT06, crossed with three strip rust-resistant wheat lines, i.e., YR5, YR10, and YR15, employed line × tester hybridization. The analysis determined that the general combining ability (GCA) and specific combining ability (SCA) variances were significantly different for examined parameters (p < 0.05). Parental lines Auqab2000 and Fatehjung16 emerged as better general combiners for earliness and yield-related attributes; however, Auqab2000 × YR5, KT06 × YR5, Khattakwal × YR10, PR128 × YR5, Khattakwal × Auqab, and KT06 × YR10, proved the top particular cross combinations for contributing features of grain yield per plant. Results also showed that lines import sufficient variety to manifest the traits under investigation. For almost all tested qualities, the value of σ2gca/ σ2sca demonstrated a non-additive gene effect, except for days to maturity, which the additive gene action influenced. The selection of superior plants should take time until later segregation generation when non-additive gene activities dominate. The genotypes chosen for the current study are crucial genetic resources for wheat’s continued gene development.
