摘要
1982年在普通小麦春冬杂交组合阿彭13/75—1297的F_1中发现部分不育株,经初步研究确定,是不同于提型的质核互作雄性不育系,称“临型不育系”,以Ls表示.在不同遗传背景的品种(系)中都能比较容易地找到它的保持系和恢复系,其细胞质未见有明显的不良作用,其柱头生活力持续时间也较长,在杂交小麦的利用研究上可能有一定的应用价值.
Some complete male sterile plants were discovered in F1 of a hybridized combination, A-PENG 13/75-1297 of common spring and winter wheat in 1982. After preliminary research, it is determined to be a nucleo-cyto plasmic interaction A-line that is different from the Timopheevi-type. It is called "LIN-type A-Line " , and symbolized as Ls". Its B-line and restoring line could be easily found in many varieties(or lines) with different genetic background. Harmful effect was not discovered in the cytoplasm. And the viability of its stigma can last a longer time.It could be used in the study and application of hybrid wheat.
