Abstract

Thirty six accessions of pearl millet germplasm along with check HHB 67 were evaluated in eight environments for eight quantitative traits and data were subjected to regression analysis and also analysed to detect the presence of crossover and non-crossover interactions. Four accessions namely, IC 285164, IC 285153, IC 285180, and IC 285175 were identified to be promising based on regression analysis, whereas accessions IC 285151, IC 285156, IC 285164, IC 285177, IC 285172, IC 285160 and IC 285178 were identified as potential ones by using crossover and non-crossover interactions concepts against standard check HHB 67. Of these accessions IC 285164 was identified as high yielding accession having specific adaptability and responsiveness to higher nitrogen regimes both by regression analysis and crossover and non-crossover interactions concept.
