Assessıng the yıeld stabılıty of nıneteen chıckpea (cıcer arıetınum l.) genotypes grown under multıple envıronments ın south-eastern anatolıa, Turkey

Abstract

The identification of high performance stable genotypes is essential for increasing sustainable chickpea production in Turkey. Hence, nineteen chickpea genotypes were examined for stability assessment in different environments in Southeastern Anatolia, Turkey. Chickpea genotypes were sown in early spring and planted in the winter. The analysis of variance showed that the genotypes and locations were significantly differed in the majority of the studied characters. The regression coefficient, deviations of the regression coefficients, coefficient of variation, ecovalence and stability variance were calculated for chickpea genotypes. The stability parameters were varied by the planting dates and environments in which the chickpea genotypes were grown. Among the studied chickpea genotypes, genotype 'FLIP98-143C' was considered as high grain yield and low b value and produced the minimum deviation regarding the regression, genotypic variance, coefficient of variation, ecovalence and stability variance. Therefore, the genotype 'FLIP98-143C' may be used as a stable and high yielding variety in the future and also it may be used in future breeding programs to develop good varieties.
