Research on Seedling Resistance to the Phytophthora Infestans (Mont.) De Bary of Tomato Cellular Mutant lines

摘要

Employing both cotyledon and hypocotyl of tomato cultivar of Alpatieva-905* and its line of Line-1 as the explants of the experimental materials, the cellular breeding for resistance to Phytophthora infestans is feasible using plant-tissue culture, while need to add various concentrations of Nystatinantibiotic chemical in MS medium. Retest results in the test-tube or at greenhouse and in field also showed that the regenerating seedlings had the higher resistance to Phytophthora infestans than the control seedlings. The results obtained in the Experiments lead to the conclusion that the regenerating seedlings are the promising mutant one for resistance to Phytophthora infestans.
