中文摘要:

植物高度的继承在二被学习使基因施主, Zhepi 1 和 Aizao 3 相形见绌,在大麦在中国繁殖。用直接十字和 para-back-cross 方法,突变而产生之遗传的测试在 Zhepi 1 和 Aizao 3 在相形见绌的基因之间被执行不仅,而且与 br, uzu,兽穴那么,或 sdwl 和最近在中国在大麦被识别了的六新奇相形见绌基因。结果证明植物高度在 Zhepi 1 和 Aizao 3 两个都被归因于后退的相形见绌基因的孟德尔式遗传。二栽培变种带的相形见绌的基因是从三一样,却不同知道并且六新奇相形见绌基因。根据现在的学习,仅仅二相形见绌基因在大麦自从 1950,在中国繁殖被使用了。

英文摘要:

Inheritance of plant height was studied in the two dwarfing gene donors, Zhepi 1 and Aizao 3, in barley breeding in China. Using direct cross and para-back-cross methods, allelic tests were carried out not only between the dwarfing genes in Zhepi 1 and Aizao 3, but also with br, uzu, denso, or sdwl and the six novel dwarfing genes that have been recently identified in barley in China. The results showed that the plant height was attributed to Mendelian inheritance of a recessive dwarfing gene both in Zhepi 1 and Aizao 3. The dwarfing genes carried by the two cultivars were the same, but different from the three known and the six novel dwarfing genes. On the basis of the present study, only two dwarfing genes have been used in barley breeding in China since 1950.
