Evaluation of Vegetable Cowpea (Vigna unguiculata (L.) Walp.) Breeding Lines for Cultivar Development

This study was conducted to evaluate 12 advanced cowpea breeding lines developed from 27 localcowpea populations of Turkey using single plant selection based on some plant characteristics and fresh pod yieldin comparison with Akkız-86 and Karagöz-86 control cultivars. Field experiments were arranged in randomizedcomplete block design with three replications and conducted at Kurupelit and Ambarköprü locations of Samsun,Turkey in 2005 and 2006. According to combined results, L3 was the superior line for fresh pod yield by 18.0 t ha-1. It was followed by L12, L13 lines and Karagöz-86 cultivar. Genotype x environment interaction was significant(P<0.01) for fresh pod yield. Stability analysis revealed that L3 line showed the best adaptation in optimal environmentalconditions among all lines/cultivars. All cowpea lines/cultivars were found to be moderately adaptable toall environmental conditions with the exception of L3, L12, L1 and L9. Based on the two years study results, L3,L12 and L13 lines were recommended for the vegetable cowpea cultivation because of their crisp, slender, stringlessand tasty pods. L3 and L13 lines were registered as the first vegetable cowpea cultivars in Turkey under thename of Pekşen and Reyhan, respectively, in April 15, 2011 by VRSCC (Variety Registration and Seed CertificationCenter, Turkey).
