摘要
以油菜为材料,利用F1、F2和回交代对油菜的硅强遗传进行了研究。火炬(易破碎)和var. Yellow Sarson和var. Brown Sarson(抗破碎)加入。抗破碎性(高硅强度)在所有杂交中都是隐性的。涉及DS-17-D (var. Brown Sarson)的杂交表明,稻米强度很可能由两个显性上位互作基因控制。b -5和B-46杂交(都是黄萨尔森品种),cv值均为0。Torch表明可能有三个基因控制唾液强度,其中两个基因在显性时似乎对第三个基因具有上位性。在这些杂交中,多瓣性状似乎由三个基因控制,其中两个基因对第三个基因的上位性导致多瓣性状,而前两个基因是隐性的。黄沙逊杂交中硅强度的偏析与多阀性状的偏析并不是独立的。
Inheritance of siliqua strength in Brassica campestris L. I: Studies of F2 and backcross populations
The inheritance of siliqua strength was studied in Brassica campestris L. using F1, F2, and backcross generations of crosses between cv. Torch (shatter susceptible) and var. Yellow Sarson and var. Brown Sarson (shatter resistant) accessions. Shatter resistance (high siliqua strength) was recessive in all crosses. Crosses involving DS-17-D (var. Brown Sarson) indicated that siliqua strength is most likely controlled by two genes that show dominant epistatic interaction. Crosses of IB-5 and B-46 (both var. Yellow Sarson) each with cv. Torch indicated the likelihood of three genes controlling siliqua strength, two of which appeared to be epistatic over the third gene when dominant. In these crosses, the multivalve character appeared to be controlled by three genes, two of which were epistatic over the third gene resulting in multivalve character when the former two were recessive. Segregation for siliqua strength in the var. Yellow Sarson crosses was not independent of segregation for multivalve character.Ke...
