Obtaining and Cytological Identification of a Set of Primary Trisomics in Cabbage

Agricultural Sciences in China 2006年第9期5卷 655-660页

作者： ZHANG Cheng-he ZHU Hai-yan LI xiao-feng shen Shu-xing CHEN Xue-ping MAN Hong XUAN Shu-xin College of Horticulture Agricultural University of Hebei Baoding 071001 P.R.China

Selection of primary trisomics of the cabbage （Brassica oleracea *** L） forms an important basis for gene chromosome mapping and for other genetic studies. The cabbage self-fertilization line - 9601 was used as material, using the root-tip cell chromosome number and pollen mother cell chromosome number identification and karyotype analysis to select the primary trisomics from the progenies of 3x x 2x in the cabbage. Many aneuploid plants with one or two extra chromosomes were obtained and a set of primary trisomics （Tri-1, Tri-2, Tri-3, Tri-4, Tri-5, Tri-6, Tri-7, Tri-8, and Tri-9, in which the Tri-1 and Tri-4 were from 2n＋2 plants and others from 2n＋ 1 plants） was acquired from these plants. Each trisomic exhibited some unique features, such as plant height, plant type, leaf type, size of flower bud, and inflorescence. The triploid crossing by the diploid is a convenient and effective way to select trisomics in the cabbage.
