三十九个小麦品种(系)抗小麦叶锈菌基因分析

PROBABLE GENES FOR LEAF RUST RESISTANCE IN 39 WHEAT CULTIVARS (LINES)

分析了39个小麦品种(系)与17个抗小麦叶锈菌近等基因系对21个叶锈菌培养物的反应。确定了9个品种可能含有的抗小麦叶锈菌的Lr基因。这些基因分别是Lr1,Lr3,Lr10,Lr14a,Lr14b,Lr16,Lr17,Lr18,Lr21和Lr26。

Reaction of 39 wheat cultures (lines) and 17 near isogenic Lr gene lines interacting with 21 Puccinia recondita f. sp. tritici cultures were compared to detemine the probable genes for seedling resistance in the cultivars. Many of the cultivars (lines) studied can be combined into groups on the basis of sharing the same genes for resistance. The cultivars may have the genes indicated in parathesis as follows:Nuo -77-17-1 (Lrl7), Nuo77 -14 - 2317 and Kehan No. 9 (Lr14b), Longmai 12 (Lr10), Dongnong 120 (Lr14a) ,Jian66 (Chuyi)(Lr18), Pmv76 - SIS (Lrl7 in addition to Lr1)and Jian60(chuer) (Lr3 in addition to Lr10),some of the cultivars (lines) may have genes in addition to the Lr genes determined.
