Increase of Male Transmission Rate of Cabbage Chromosome by Limited Pollination in Alien Chromosome Addition Lines of Chinese Cabbage with Single Cabbage Chromosome

Abstract

In order to maintain alien chromosome addition lines, it is very important to increase the level of male transmisslon rate. By limited pollination with a small number of pollen grains, the rates of late-flowering plants which might be due to a cabbage chromosome increased significantly in alien chromosome addition plants (2n = 21) of Ch{nese cabbage with single cabbage chromosome
