“…In the F2 generation, examining the effects of parents and hybrids on GCA and SCA in terms of the number of pods per plant; Magar et al, (2016), Olunloyo et al (2019), and Pallavi and Chaudhary (2020) obtained similar results to our findings. (Table 2).…”

“…It reveals that selection in future generations would be appropriate because the genes that affect the pod length in the plant are not additive in the examined hybrid generations (Pallavi et al, 2020;Verma et al, 2020), found different results. But Magar et al (2016), Kumari andChauhan (2018), andOlunloyo et al (2019) found similar results.…”

“…This shows us that cytoplasm or cytoplasm x nucleus interactions cause significant changes in this feature(Table 2). Working on the pod length, Dias et al (2016), Magar et al (2016), Kumari and Chauhan (2018), Olunloyo et al (2019), Owusu et al (2020), Pallavi et al (2020), andVerma et al (2020) found the GCA and SCA values of different numbers of parents and crosses to be important for this trait.…”

“…They can be considered as suitable combinations that can be used to increase the number of seeds in the pod, as they have the effect of SCA. In many studies, the effects of GCA and SCA for the number of seeds per pod were determined (Dias et al, 2016;Magar et al, 2016;Gupta et al, 2017;Kumari and Chauhan, 2018;Olunloyo et al, 2019;Purnamasari et al, 2019;Owusu et al, 2020;Pallavi et al, 2020;Verma et al, 2020).…”

Olunloyo et al (2019) stated that cowpea seed yield was influenced by both added and non-added genes.…”

Cowpea is an essential economic crop in underdeveloped and developing countries mainly grown by small farmers. The parents and F2 populations obtained for the F1 generation were planted, in 3 rows of 2 m in length, with row spacing of 45 cm, row spacing of 10 cm and in the ecological conditions of Konya in 2021. The 20 F2 populations and 5 parents were evaluated in the 2021 grown season. General combining ability (GCA) effects for various parents differed significantly. “Sırma” gave significant, positive GCA effects for the number of pod per plant, number of seeds per plant, seed yield per plant and protein yield in plant. Significant, positive specific combining ability (SCA) effects were smaller and less significant than GCA effects. The non-additive dominant gene effect was determined for all the traits. Heterosis of the F2 over the high-parent was observed in five F2 populations. In the terms of combining ability for yield, the best parent was “Sırma”. The heterosis for a yield of F2 hybrids resulted mainly from an increased number of seeds per plant, hundred seed weight. These results suggest that high yielding F2 cowpea populations can be developed that may contain acceptable levels of superior agronomic and technological characteristics.
