Contribution to the methods of inducing polyploid tomatoes



Contribution to the methods of inducing polyploid tomatoes



Comptes Rendus de l' Academie Bulgare des Sciences 41(3): 81-82



A male-sterile parthenocarpic line, Start BR (ps2 pat2), was treated at various stages (seed, cotyledon, first pair of true leaves and 7-8 leaves) with 0.1, 0.2 and 0.3% colchicine for 24, 28 and 32 h. Only treatment at the cotyledon and first-leaf stage proved effective in polyploid production, and only colchicine concentrations >0.1%.
