Interspecific hybridization as an inducing factor of ogura-type cms in Brassica plants
Submitted by Гость (not verified) on Tue, 09/10/2024 - 18:38In our recent study the one male sterile plant BKBu3 has been found in BC1-progeny from interspecific crossing of tetraploid fertile B. oleracea and allotetraploid fertile B. carinata lines. The flowers of male sterile plant had reduced, necrotic anthers, and no fertile pollen was observed. However, other organs of flowers were phenotypically and functionally normal. No segregation in sterility/fertility morphology of the BC2 progeny plants indicated a cytoplasmic mode of male sterility inheritance.
