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.

Highlights

Pea (Pisum sativum L.) is an important plant
The 1000 seed weight of the parents versus crosses were significant at the 5% level, while the plant height, pods per plant, seeds per pod, seeds per plant and seed yield per plant values were significant at the 1% level
The VeselaxArdahan hybrid for seeds per pod; Debrecen3xArdahan, Sel 3-25xUSA1, USA5xArdahan, USA5xGap pembesi, USA5xMilwa, VeselaxKirazli and VeselaxUSA1 hybrids for seeds per plant; Debrecen3xUSA1, Sel 3-25xGap Pembesi, Sel 3-25xKirazli, USA5xArdahan, USA5xMilwa and VeselaxKirazli hybrids for seed yield per plant; Sel 3-25xGap Pembesi, Sel 3-25xKirazli, Sel 3-25xMilwa, USA5xUSA1, VeselaxArdahan and VeselaxKirazli hybrids for 1000 seed weight had positive and significant specific combining effect (Table 3)

Summary

Introduction

Pea (Pisum sativum L.) is an important plant Because it has high adaptability and seed yield, seeds and hay are used as animal fodder, seeds have excellent potential as a cheap source of high-quality protein (Kahraman et al 2015; Shaalan et al 2018). It is a good crop rotation plant and it can be used as green fertilizer plant (Uzun & Acikgoz 1998). The genetic variation among pea cultivars is low due to the limited number of parent plants used in breeding programs and the narrow gene pool (Espósito et al 2007; Şimşek & Ceyhan 2017). The general combining ability is related to the additive effects of genes, while the specific combining ability is related to the dominance effects of genes
