Abstract

Bu çalışma, Türkiye’nin 27 yerel börülce populasyonundan bazı bitkisel özellikleri ve taze meyve verimine

dayanarak tek bitki seleksiyonu ile geliştirilen ileri börülce ıslah hatlarını Akkız-86 ve Karagöz-86 kontrol çeşitleri

ile karşılaştırmalı olarak değerlendirmek amacıyla yürütülmüştür. Tarla denemeleri Şansa Bağlı Bloklar Deneme

desenine göre üç tekrarlamalı olarak düzenlenmiş ve Samsun ilinin Kurupelit ve Ambarköprü lokasyonlarında

2005 ve 2006 yıllarında yürütülmüştür. Birleştirilmiş sonuçlara göre en üstün hat 18.0 t ha-1 taze verim ile L3 olarak

bulunmuştur. Bunu L12 ve L13 hatları ile Karagöz-86 çeşidi izlemiştir. Taze meyve verimi bakımından genotip

çevre interaksiyonu çok önemli (P<0.01) bulunmuştur. Stabilite analizi, tüm hat/çeşitler arasında L3 hattının optimum

çevre şartlarında en iyi uyum gösterdiğini ortaya koymuştur. L3, L12, L1 ve L9 dışında kalan tüm börülce

hat/çeşitleri tüm çevrelere orta derecede uyumlu olarak bulunmuştur. İki yıllık çalışma sonuçlarına dayanarak, L3,

L12 ve L13 hatları gevrek, ince, kılçıksız ve lezzetli meyveleri nedeniyle sebze yetiştiriciliği için önerilmiştir. L3

ve L13 börülce hatları 15 Nisan 2011’de TTSM (Tohumluk Tescil ve Sertifikasyon Merkezi) tarafından Türkiye’nin

ilk sebze börülce çeşitleri olarak sırasıyla Pekşen ve Reyhan adları ile tescil edilmiştir.

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

Abstract

This study was conducted to evaluate 12 advanced cowpea breeding lines developed from 27 local

cowpea populations of Turkey using single plant selection based on some plant characteristics and fresh pod yield

in comparison with Akkız-86 and Karagöz-86 control cultivars. Field experiments were arranged in randomized

complete 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 environmental

conditions among all lines/cultivars. All cowpea lines/cultivars were found to be moderately adaptable to

all 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, stringless

and tasty pods. L3 and L13 lines were registered as the first vegetable cowpea cultivars in Turkey under the

name of Pekşen and Reyhan, respectively, in April 15, 2011 by VRSCC (Variety Registration and Seed Certification

Center, Turkey).
