Abstract:
The investigation was aimed to identify stable genotypes of durum wheat which can perform consistently under multiple environments. The experiment was conducted in Research Area of CCS Haryana Agricultural University, Hisar during rabi 2015-16. In the present investigation seven released varieties of durum wheat were evaluated on four environments (timely vs late sown, irrigated vs drought) in randomized block design with three replications. Grain yield data was collected from randomly selected five plants of each genotype and used to carry out GGE biplot analysis using the R software and GGEBiplotGUI package. Analysis of variance revealed significant genetic variability among the genotypes. Significant variability was also observed due to both environment and GEI. The four environments were grouped into three major groups. Both irrigated environments were grouped together and were more alike for genotypic comparisons. Genotype WHD 948 was the most stable genotype in all the environments.
