Determination of combining ability and hybrid performance of some pea (Pisum sativum L.) lines obtained by crossing with line X tester analysis method

Abstract

Three female (USA5, Vesela and Oranlij) and three male (Ater, Taskent and Ozkaynak) field pea genotypes were used as parents and crossed in 2013 and 2014 according to the Line x Tester analysis method. The obtained F1 hybrids and the parents were planted on 8 November 2016. The aim of this study was to determine the combining ability and cross performances of pea (Pisum sativum L.) lines obtained by hybridization using Line x Tester method. The study was carried out in 2016-2017 at Bursa Uludag University, Faculty of Agriculture, Department of Field Crops, Bursa (40 degrees 11' North, 29 degrees 04' East). In the research, biological yield (g/plant), seed yield (g/plant), straw yield (g / plant), harvest index (%) and 1000-seed weight (g) were determined. For these characters, mean values, general and specific combining abilities and heterosis and heterobeltiosis values were determined for the parents and F1 generations. As a result, USA5 x Taskent, Vesela x Ates, Vesela x Taskent and Urtiniti x Ozkaynak genotypes were identified as significant genotypes in terms of both seed and straw yields.
