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 andhybrid performance for seed yield and yield components in pea(Pisum sativum L.) genotypes. Field experiments were carried out in2016-2017 during the winter growth period at Bursa UludagUniversity,Faculty of Agriculture,Agricultural Research andApplication 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 usedas parents. The all plants were planted on November 8, 2016. Theexperiment was carried out in the randomized complete block designwith three replications. Plant height (cm), pods per plant (number),seeds per pod (number), seeds per plant (number), seed yield (gplant-1), and 1000-seed weight (g) of the plants were determined. Inconclusion, the Sel 3-25, Ardahan, Gap pembesi, and Kirazligenotypes were decided to be suitable for use in future hybridizationstudies for seed yield due to high general combining ability. Also,Debrecen3xUSA1, Sel 3-25xGap pembesi, Sel 3-25xKirazli,USA5xArdahan, USA5xMilwa, and VeselaxKirazli hybrids weredetermined for seed yield as the best hybrid combinations due to highspecific combining ability.
