Abstract

Neya et al., J. Appl. Biosci. 2017 Diallel analysis of pod yield and 100 seeds weight in peanut (Arachis hypogaea L.) using GRIFFING and HAYMAN methods. 11619Journal of Applied Biosciences 116: 11619-11627 ISSN 1997-5902 Diallel analysis of pod yield and 100 seeds weight in peanut (Arachis hypogaea L.) using GRIFFING and HAYMAN methods. ABSTRACT Objectives: The lack of information on yield and yield components are an obstacle in peanut (Arachis hypogaea L.) breeding for productivity improvement in BURKINA FASO. This work is to elucidate the mode of heritability of genes that govern 100 seed weight and pod yield, and identify the best parents for recommendation in hybridization programs. Materials and methods: A 6 x 6 full diallel with breeding lines such as GM656, NAMA, PC79-79, AS, SH470P and CN94C; was conducted. Two models were used, one of GRIFFING (1956) and the second of HAYMAN (1954), to detect the general (GCA) and specific (SCA) combining ability. GCA/SCA ˂ 1 for 100 seed weight and GCA / SCA ˃ 1 for pod yield. D-H1 difference reveals existence of an over dominance for 100 seed weight and partial dominance for pods yield. Heritability in the narrow sense is 48.7% for the pod yield and 55.3% for the weight of 100 seeds. Conclusion and Application of results:These results show that the pod yield is governed by genes with additive effects and non-additive effects with more additivity effects. However, the weight of 100 seed is essentially governed by genes with additive and non-additive effects with a preponderance of non-additive effects and dominance. HAYMAN graphical analysis indicates that CN94C, SH470P, AS have a lot more genes that control pods yield and 100 seed weight. These breeding lines may be recommended in hybridization for improvement of productivity. The importance of Reciprocal effects (RCE) shows that we must consider maternal effects in hybridization for breeding programs. In these programme

Diversity and inheritance in cowpea (Vigna unguiculata) on protein and yield components characters

“…Diallel random model, analysis showing general combining ability significantly indicates that traits are more influenced by additive gene effect, the analysis that showing significant specific combining ability indicates traits are more influenced by non-additive gene effect. Traits that have a greater general combining ability variance than specific combining ability are thought to be more influenced by additive genes (Fasahat et al 2016), the traits with general combining ability are indicated traits more influenced by additive gene effect, which is weight of 100 seed, number of seeds per pod and number of pods per bunch are different from the results obtained on peanuts (Neya et al 2017) the weight of 100 seeds is influenced by the effects of non-additive genes Similar results were reported by Idahosa and Alika (2013) in cowpea for 100 characters of seed weight which were influenced by additive and non additive effects. The pods reported by Neya et al (2017) were more influenced by the effects of additive genes obtained from the results of GCA / SCA ratios greater than 1 while in the Idahosa and Alika (2013) results obtained that the number of seeds per pod was influenced by the additive gene effect and the non-additive that can be predicted from significant value of the general combining ability and specific combining ability according to Medici et al (2004) significant general combining ability indicates that at least one of the results of the crossing affected by the effects of additive genes while significant specific combining ability indicates that at least one of the elders affected by the effect of a non-additive gene or the observed traits affected by more than one locus.…”

“…Yield component consists of 100 seeds weight, number of seeds per pod, number of pods per bunch, number of pods per plant, and yield per plant (Table 3). In the analysis of variance, it was found that the general combining ability (GCA) the weight of 100 seeds was significant at 0.01 level, whereas in peanuts (Neya et al 2017) the results showed that the weight of 100 seeds has been significant at specific combining ability (SCA). The number of seeds per pod was significant at the 0.01 level different from the results of the study by Dahosa and Alika (2013), the number of seeds per pod has been significant value, in B I O D I V E R S I T A S 20 (5): 1294-1298, May 2019 1296 general, combining ability (GCA) and specific combining ability (SCA) while in peanut (Jogloy et al 2005), the yield character pods, seed yield, and weight of 100 seeds have been significant in general combining ability (GCA).…”

Combining ability and heterosis analyses for oil and healthy fatty acid composition in groundnut (Arachis hypogaea L.)

“…Diallel crosses and combining ability studies provides an opportunity to know the mode of inheritance and provide a clear concept for breeders to understand the basis on which certain parental traits could be exploited in the breeding programme. Additionally, general combining ability (GCA), specific combining ability (SCA) variance provides breeders an insight on additive and non-additive inheritance, respectively where reciprocal combining ability (RCA) signify the maternal effect (13). Heterosis study also helps the breeder to assess the superiority and inferiority of the F1 hybrids as compared to their parents and also for selecting suitable parents for achieving higher genetic gain.…”

Past, Present and Future Perspectives on Groundnut Breeding in Burkina Faso

“…Most research results are confined to annual reports of individual projects with little published in international journals [25]. To our knowledge, publications in recent years have focused mainly on yield evaluation [26] and disease of local and exotic varieties for early leaf spot [27,28]. Earlier research activities involved the evaluation of resistance to foliar diseases in lines introduced from ICRISAT (International Crops Research Institute for the Semi-Arid Tropics) or the USA through the Peanut CRSP (Peanut Collaborative Research Support Program) [29][30][31] and similar development programmes.…”
