Evaluation of advanced cotton genotypes at the field conditions of different locations of Sindh and Balochistan

Abstract

Thirty advanced candidate cotton lines were tested during two consecutively years (2019 and 2020) and at seven locations of Sindh and Baluchistan Provinces in national coordinated varietal trials (NCVT). The trials were conducted to evaluate promising line for seed cotton yield and fiber properties against standard check variety. The results revealed highly significant differences among the varieties during both the years. In 2019, on an average of seven locations, top ten high yielding varieties recorded were Rustam-11, GH-Sultan, Saim-102, CIM-775, Diamond-2, NIA-88, NIA-89, ASPL-710, IR-NIBGE-15 and CRIS-644 which given maximum seed cotton yield. In 2020, on an average of top ten high yielding varieties were GH-Sultan, CIM-775, NIA-88, Diamond-2, Cyto-535, Siam-102, FH-Anmol, Cyto-226, ASPL-710 and NIAB-512 which attained highest seed cotton yield. However, when the results of 2019 and 2020 were summed up, top ten high yielding varieties were GH-Sultan, CIM-775, Rustam-11, Diamond-2, NIA-88, Siam-102, Cyto-535, NIA-89, ASPL-710 and IR-NIBGE-15. It was noted from the present research that among top 10 high yielding varieties during both years, only six varieties (GH-Sultan, CIM-775, Diamond-2, NIA-88, Siam-102 and ASPL-710) were stable with yield performance due to the fact that these varieties keep their superiority in individual year (2019 and 2020) it is suggested that the top six high yielding varieties (GH-Sultan, CIM-775, Diamond-2, NIA-88, Siam-102 and ASPL-710) with stability in performance must be approved by the provincial seed council of Sindh and Balochistan to revive the cotton production of the provinces and not to waste/garbage this high yielding stuff.
