Studies on seed production in Indian cauliflower under sub-tropical regions of Himachal Pradesh

Five cultivars of Indian cauliflower (early and mid season) were grown under four dates of sowing. Earlier sowing (1st September and 15th August) resulted in vigorous plants with larger number of inflorescence stalks/plant, thus gave the higher seed yield. Amongst the genotypes, Maghi has shown higher growth potential in terms of size of the curd, number of inflorescence stalk produced and number of siliquae per stalk. Early Kunwari was the earliest to bolt and flowers and recorded the maximum seed germination. Genotype Maghi, Early Kunwari and Pusa Deepali yielded the maximum seed when sown on 1st September followed by 15th August.
