Abstract

Cauliflower hybrids belonging to the late (Snowball) group were evaluated for their mean performance and heterosis using the Ogura cytoplasmic male sterility (CMS) system. A total of 30 F1 hybrids were developed by crossing three CMS lines with ten diverse testers through a Line × Tester mating design. These hybrids were assessed for ten key morphometric traits related to yield performance. Among the CMS lines, UHF-CAUCMS- 2 exhibited superior performance for most traits, except for days to 50% curd maturity and harvest index. Among the testers, PSBK-1, PSBKT-25, and Early London showed promising results for the majority of the yield-contributing traits. Based on per se performance and significant heterotic effects, the hybrids UHF-CAUCMS- 1 × Snowball Super, UHF-CAU-CMS-1 × PSBK-1, and UHF-CAU-CMS-2 × Early London emerged as the topperforming combinations. These crosses demonstrated notable improvements in curd size index, marketable curd weight, and harvest index, making them promising candidates for commercial cultivation, needs further validation through multi-location trials.
