Tal Rahata Dist. Ahmednagar Maharashtra, India A mutation technique provides good exciting opportunities for modern plant breeding. Induced autotetraploidy has potential for genetic improvement of various crops species. The crops like Sunnhemp (2n=16) and Dhaincha (2n=24) are diploid species, which are included in family Fabaceae and mostly cultivated as yielding of bast fibre green and manure purpose in all over the India. The M₂ generation in these plants showed mitotic chimera changes due to colchicine treatment. The chimeric mutants mitotic cell division were showed irregular chromosome number and resulting a mixoploid composition of both plants. https://www.agriculturejournal.org/volume13number1/induced-tetraploid-in-sunnhemp-crotalaria-juncea-l-and-dhaincha-sesbania-bispinosa-jacq-w-wight/ Autotetraploidy; Chimera; Colchicine; Mitosis; Mixoploid; Mutants
