Stability analysis for yield and quality in brinjal (Solanum melongena L.)

Abstract

Assessment of genotype x environment interactions in crop breeding programs is assuming importance for identification of genotypes with wider adaptability. This is more so in brinjal (Solanum melongena L.), one of the most common, highly productive and popular vegetable crops of India, grown round the year and highly influenced by varied agro-climatic conditions [1]. Studies on stability of brinjal over the different cropping seasons for yield and quality are however, quite limited. In this context, the present investigation was undertaken to elucidate information on the stability of brinjal genotypes for fruit yield, yield components, quality and physiological characters with regards to the three different cropping seasons, namely summer, rainy and late summer.
