Abstract: A two-year field experiment was conducted at the Research Farm of Cotton Section, Department of Genetics and Plant Breeding, Chaudhary Charan Singh Haryana Agricultural University, Hisar to illustrate the effects of weather parameters on biochemical parameters viz. protein content, oil content, sugar content and gossypol content of desi cotton varieties HD 123, HD 324 and HD 432 grown in different environmental conditions. Experimental material was planted on 10 April, 15 May and 5 June during 2015 while on 26 April, 5 May and 2 June during 2016 in a Randomized Block Design (RBD) with six replications. The flowering during both the years started from early July and completed by end of September during both the years. Flower were tagged on weekly basis and seed cotton picked from them were ginned separately and thus this seed was used to estimate the biochemical parameters of different sowing dates and their correlation with seed germination. The response of various biochemical constituents differed in different sowing periods. Early sown condition was suitable for the development of biochemical traits in desirable direction. It leads better seed development which resulted in increased the seed. Seed germination with different biochemical parameters showed positive correlation except gossypol content which showed negative correlation.
