对优良小麦白粉病抗源贵农２１的利用研究表明：在以贵农２１为亲本之一的单交、三交和复合杂交等不同组配方式配制的１００个杂交组合中，鉴选出Ｆ６～Ｆ７对白粉病具有优良抗性（高抗—免疫）和优良农艺性状的９５４３、９６２１、９６３９、９６２４７、９６２５０等品系进入了品种比较和生产试验，并选出９６１１４、９６１１９等优良抗源供抗病育种研究利用。初步明确了小麦抗白粉病育种优良抗源贵农２１的利用途径。
The study on the utilization of powdery mildew resistant Guinin21 with excellent wheat powdery mildew indicated that among 100 hybrid combinations with different combinations of single pay, triple pay and multiple crosses, ~ F7 entered the variety comparison and production test with 9543,9621,9639,96247,96250 and other strains with excellent resistance (high anti-immune) and good agronomic traits to powdery mildew and selected the excellent anti-source for 96114,96119 Disease resistance breeding research and utilization. Preliminary identification of wheat resistant to powdery mildew breeding of good use of resources Guinin21 ways.
