Stability Analysis of Yield and Yield Components in Chickpea (Cicer Arietinum L.)

Abstract

An experiment was carry out to estimate genotype acute environment interaction and the stability parameters following Freeman et al model The experiment was setup during the four consecutive rabi seasons of to at the Botanical Research Field University of Rajshahi Rajshahi Bangladesh and thirteen yield and yield components of eight genotypes of chickpea have been considered The analysis of variance showed that the genotypes and year were significantly different for most of the character The results of joint regression analysis exhibited that the mean square due to genotypes were significant for all studied traits Except DMF all studied traits were exhibited significant variation due to environmental change Combined regression displayed significant values for NPBFF NSBFF NPBMF NSBMF PdW P and NS P in comparison to residual Heterogeneity of regression item was found to be non significant for all the traits except NSBFF Residual item was significant for all the characters except PHFF NSBFF DMF PHMF and NPBMF In this study the genotype for DFF NPBFF and DMF genotype for NSBFF and NPBMF genotype for NSBMF genotype for NPBFF and NPBMF genotype for NSBMF and SW P genotype NPBFF and NPBMF were considered as stable genotypes nbsp
