Genotype x environment interaction for yield and yield components in pearl millet

Seventeen genotypes of pearl millet were assessed for stability under four different environments for twelve characters. The major portion of G x E interaction was linear in nature for all other characters except days for 50 per cent flowering, plant height. No. of total and effective tillers plant'1. This indicated that prediction over environment for these characters would be possible. Significance of pooled deviation suggested importance of non-linear components for all the characters, therefore both linear and non-linear components appear to be important. The genotypes 981103 and 981064 which possessed average stability and wider adaptability for grain yield and also displayed either average or above and below average sability for other characters. The gene types 981344. 981338, 981327 and 981326 exhibited above average stability for grain yield and also expressed stability for other characters. From the stability analysis it can be concluded that none of the genotype was found to be ideal with average stability for all the characters. However the genotypes 981103, 981064, 981344, 981338. 981327 and 981316 showing stability for grain yield along with one or more yield components could be considered In future bleeding programme.
