Combining abilities and heterotic groups for seed yield and yield components in pea (Pisum sativum L.)

Abstract

The aim of this study was to investigate the combining ability and hybrid performance for seed yield and yield components in pea (Pisum sativum L.) genotypes. Field experiments were carried out in 2016-2017 during the winter growth period at Bursa Uludag University,Faculty of Agriculture,Agricultural Research and Application Center in Bursa, Turkey. In the study, four female (Debrecen3, Sel 3-25, USA5, and Vesela) and five male (Ardahan, Gap Pembesi, Kirazli, Milwa, and USA1) pea genotypes were used as parents. The all plants were planted on November 8, 2016. The experiment was carried out in the randomized complete block design with three replications. Plant height (cm), pods per plant (number), seeds per pod (number), seeds per plant (number), seed yield (g plant(-1)), and 1000-seed weight (g) of the plants were determined. In conclusion, the Sel 3-25, Ardahan, Gap pembesi, and Kirazli genotypes were decided to be suitable for use in future hybridization studies for seed yield due to high general combining ability. Also, Debrecen3xUSA1, Sel 3-25xGap pembesi, Sel 3-25xKirazli, USA5xArdahan, USA5xMilwa, and VeselaxKirazli hybrids were determined for seed yield as the best hybrid combinations due to high specific combining ability.
