“…The results suggest that both additive and non-additive gene effects are involved in the expression of ELS disease resistance in groundnut. Similar findings of additive and non-additive gene actions for yield-related traits and diseases, including ELS resistance, were reported earlier [1,[26][27][28][29]. In addition, the reciprocal effect was highly significant for the two traits, indicating the contribution of cytoplasm and nuclear genes effects to ELS resistance.…”

Early leaf spot (ELS) is one of the major biotic constraints of groundnut production in West and Central Africa. A study using 6 × 6 F2 full diallel populations from six parents (NAMA, B188, PC79-79, QH243C, TS32-1, and CN94C) was conducted to assess the mode of inheritance of ELS resistance traits. The F2 and parents were grown in a randomized complete block design with three replications. Data was collected on ELS disease severity, and an area under disease progress curve (AUDPC) was estimated. The results revealed that additive and non-additive gene actions were involved in the inheritance of the ELS resistance traits, but additive gene action was predominant. Significant reciprocal cross effect was observed, suggesting cytoplasmic effect on ELS resistance. Graphical analysis also revealed the predominance of additive gene action for ELS resistance. The results suggest that early generation selection should be effective for ELS resistance. Looking at the distribution of array points along with the regression line, parental lines NAMA, PC79-79, and B188 would be suitable as good donors in an ELS disease resistance breeding program.

“…The interaction components 'i', 'j' and 'l' component were found non-significant and similar sign observed for genetic component dominance 'h' and dominance x dominance 'l', with presence of complimentary epistasis. The presence of complimentary epistasis was matched with the finding given by Mohan Vishnuvardhan (2011).…”

The study was carried out to investigate genetic nature and magnitude of gene effect for yield contributing character in groundnut by using six parameter model of generation mean analysis. Two crosses viz., SBXI × Phuleunnati and SBXI × Girnar 4 were made involving two parents during Kharif 2021. Six generations (P 1 , P 2 , F 1 , F 2 , BC 1 and BC 2 ) were obtained by mating two male parents with common female and further studied for nine quantitative characters. The significant analysis showed the presence of additive, dominant, and epistatic gene interactions. Hence F 1 , F 2, BC 1 and BC 2 generations of each cross were evaluated along with their parents to assess the nature of gene action involved for various characters which in turn helps in formulating an effective and sound breeding programme in groundnut. Additive gene action along with additive × additive (i) followed by dominance (h) was found significant for the characters viz., days to maturity, dry pod yield, shelling %, harvest index, sound mature kernel. For improvement of these characters, one should follow the simple selection in early segregating generations.For pod yield and its components, the dominant component (h) and dominance x dominance (l) gene interaction was found significant for most of the characters viz., days to maturity, dry pod yield per plant, shelling %, harvest index, these characters can be improved by postponing selection in later generations.

Groundnut rust caused by Puccinia arachidis Speg. is a major cause of yield and quality losses in groundnut (Arachis hypogaea L.) in the warm-humid tropics including Tanzania. Breeding and deployment of rust resistant cultivars with farmer-preferred attributes will bolster groundnut production and productivity. The objective of this study was to determine the combining ability effects and gene action controlling rust resistance in groundnut genotypes for breeding. Twelve selected and complementary parental lines were crossed in a diallel design, to develop F1 progenies, which were advanced to the F2 for individual plant selection. Thirty-three successful partial crosses and the 12 parents were field evaluated using a 5 × 9 alpha lattice designs with two replications over two seasons in Tanzania. The tested genotypes exhibited significant (P < 0.05) variation for rust resistance, yield and yield-related traits. There existed significant (P < 0.05) difference on the general combining ability (GCA) effect of parents and the specific combining ability (SCA) effect of progeny for the assessed traits indicating that both additive and non-additive gene effects conditioned trait inheritance. The Bakers’ ratios indicated that the non-additive gene effects predominantly controlling rust resistance and yield components. This suggested that transgressive segregants could be selected for improved rust resistance and yield gains in the advanced pure line generations. Genotypes ICGV-SM 05570 and ICGV-SM 15567 were the best general combiners for rust resistance and grain yield. The crosses ICGV-SM 16589 × Narinut and ICGV-SM 15557 × ICGV-SM 15559 were identified as the best specific combiners for rust resistance with moderate yield levels and medium maturity. Genotypes with desirable GCA or SCA effects were selected for further breeding.
