Genotype × environment interactions and stability analysis for grain yield in pearl millet [Pennisetum glaucum (L.) R. BR.]

The present investigation was carried out at Regional Research Station, Anand Agricultural University, Anand during the years 2019-20 to 2020-21 to study the phenotypic stability for grain yield in pearl millet genotypes. The experimental materials consisted of 91 genotypes; comprising 70 hybrids developed using line × tester design, five CMS lines and 14 testers, and two standard check hybrids GHB 538 and GHB 732. The mean square due to genotypes × environment interactions were significant for grain yield per plant, which revealed that genotypes interacted considerably with environment. Higher magnitude of G × E (linear) variance compared to G × E (non-linear) variance for grain yield per plant indicated that major portion of interaction was predictable in nature. The hybrids ICMA₁-04999 × J-2587, ICMA₁-98222 × J- 2604, ICMA₁-98222 × 110-SB-15, ICMA₁-98222 × 69-SB-18, ICMA₁-98444 × J-2290, JMSA₁-20158 × J-2479, JMSA₁-20158 × J-2539, JMSA₁-20158 × ICMR-15758, JMSA₁-20159 × J-2479, JMSA₁-20159 × J-2590 and JMSA₁-20159 × 69-SB-18 were identified as stable and widely adapted for grain yield per plant.
