“…The gca: sca ratios were less than unity for all other traits suggesting that these characters were governed predominantly by non-additive component. Similar kind of non-additive gene action was reported earlier for kernel yield per plant, pod yield per plant (Shoba et al, 2010, Gor et al, 2013, Prabhu et al, 2014and Waghmode et al, 2017, primary branches per plant, pegs per plant, pods per plant (Jivani et al, 2009), mature pods per plant and 100-kernel weight (Shaik Nisar Ahmed, 1995, Ganesan et al, 2010, for shelling percentage (Kuchanur et al, 1997, Mothilal et al, 2010 and for pod yield (Makne et al, 1992, Dasaradha et al, 2004, Ganesan et al, 2010and Mothilal et al, 2010. Similarly the importance of additive gene action in the inheritance of days to maturity was reported by Basu et al, (1987) whereas for plant height both additive and non-additive gene effects were reported by Habib et al, (1985).…”

“…The estimates of backer ratio and (a/b) ratio of Jones method, revealed the feasibility of selection in early segregating generations for plant height, number of podsper plant, number of seedsper plant, 100-pod weight and shelling %. Overall these findings are in accordance with results reported by Reddy et al, (2017) and Waghmode et al, (2017).…”

A half diallel set including diverse five parental peanut genotypes was evaluated at Ismailia Agricultural Research Station, ARC,Ismailia Governorate,Egypt using randomized complete block design with three replications to estimate mean performance,combining ability,heterosis and nature of gene action.Highly significant genotypes and its components of parents,crosses and parents vs.crosses mean squares were detected for all studied traits.Highly significance of general and specific combining ability was observed for all studied traits.Additive gene action governed in plant height, number of pods/plant, number of seeds/plant,100-pod weight and shelling %. Ismalia 2,Line 360 and Giza 6 seemed to be the best combiners for pod yield /feddan and most of its components.The best cross combinations were detected in F1 crosses, P2 ×P3 for seed weight /plant and P3 × P5 and P4 × P5 for pod yield / feddan.Significant or highly significant values and high values of the dominance component (H1) were also observed for the most studied traits. P5 carried the most dominant genes responsible for the expression of seed weight/plant and pod yield / feddan, while, P4 for seed weight / plant and P1 and P2 for pod yield / feddan possessed high concentration of recessive genes. It could be concluded that, Ismalia2, Line 360 and Giza6 could be used as donors parents to improve yield and its components of peanut in the breeding program,also, the crosses P2 ×P3 , P3 × P5 and P4 × P5 with high SCA may be exploited for the development of hybrids as they had high per se performance.

“…Selection for these traits should be based on evaluations across multiple environments (Manivannan et al, 2008). Similar results have been reported by Vishnuvardhan (2011), Waghmode et al (2017); Onyia (2011); Hariprasanna et al (2008) andShobaet al (2010) in the genetic analysis of groundnut genotypes.…”

Background: Groundnut is a globally significant oil crop. It possesses diversity in the nutritional and medicinal values. Groundnut kernels contain 48%-50% oil, 26%-28% protein and vitamins B and E. Continuous efforts to enhance groundnut productivity is the main driving force for the current study. Methods: Line × Tester analysis was carried out to estimate the gene action of yield and its attributing traits for their improvement. Seven lines viz., VRI 7, VRI 8, VRI 9, VRI 10, K 6, GG 7 and CO 7 and eight testers viz., IGCV 15402, IGCV 15412, IGCV 15432, IGCV 15427, IGCV 15426, IGCV 15408, IGCV 15410 and IGCV 15388 were crossed to obtain 56 crosses. GCA and SCA variance revealed the importance of both additive and non-additive gene action of all the traits. Result: The study observed significantly higher specific combining ability (SCA) variances compared to general combining ability (GCA) variances, indicating a predominant role of non-additive gene action in trait control. Line VRI 7 was observed best GCA, particularly for pod yield and other traits making it a promising variety for pod yield enhancement programs in the future. The SCA for hybrid VRI 8 × ICGV15426 and VRI 7 × ICGV15402 revealed superior performance in terms of pod yield per plant. Notably, the VRI 7 × ICGV15402 cross exhibited outstanding performance across all traits, highlighting the prominence of a parent with strong GCA. The study recommends early-generation selection as a strategic approach for improving groundnut breeding efforts.
