近年来,从小麦引种工作中,初步鉴定选出一些对小麦条锈病、赤霉病、白粉病和黄矮病抗性较好的材料,共200个品种,分别在武功、汉中、安康、商洛、洛川、蒲城、长武七处进行多点试验,以了解其适应性和抗逆性,为选拔利用提供依据。根据三年异地鉴定,将部份适应性强,抗逆性好的品种,介绍如下,供小麦抗病育种选用。一、V.P.M.X.Moisson:原产法国,1977年引入许多系,表现较好的有四个系。该品种有山羊草和波斯小麦血统,冬性,叶挺举,在武功大田接种鉴定,对条中17、18、20、21、22、23号条锈生理小种免疫。并抗叶锈病、白粉病,株高100厘米,茎秆粗硬,抗倒伏。穗长7.9厘米,白壳、顶芒、红粒、半硬质,千粒重30.3克。成熟期6月15日,晚熟,但穗
In recent years, from the introduction of wheat, initially identified some of the wheat stripe rust resistance, scab, powdery mildew and yellow dwarf disease better material, a total of 200 varieties, respectively, in martial arts, Hanzhong, Ankang, Shangluo , Luochuan, Pucheng, Changwu seven multi-point test to understand its adaptability and resistance to provide the basis for selection and utilization. According to three years of identification in different places, some varieties with good adaptability and good resistance will be introduced as follows, which will be used for wheat breeding. First, V.P.M.X.Moisson: Origin France, introduced in 1977, many departments, performed well in four departments. The varieties of goat grass and Persian wheat descent, winter, leaves Tingju, inoculation identification in martial arts field, the strip 17,18,20,21,22,23 rust race physiological races immune. And leaf rust resistance, powdery mildew, plant height of 100 cm, stem stubborn, lodging resistance. Spike length 7.9 cm, white shell, top Mango, red, semi-hard, 1000 grain weight 30.3 grams. Mature on June 15, late maturity, but spike
