| 中文摘要: |
| 小麦新品种定丰9号是甘肃省定西市旱农中心1985年选用“07802中/81194”的F1作母本,1986年再次选用“630”作父本进行复合杂交于1998年选育而成。该品种产量高,全国北方春小麦区域试验结果表明,在适种区平均产量5 010.3 kg/hm2,较统一对照宁春10号增产15.99%;抗病性强,成株期对锈病条中29、30、31Hy-III及混合菌表现免疫;品质优良,籽粒粗蛋白含量17.73%,赖氨酸0.58%,淀粉含量58.56%;根系发达,抗旱性强;叶片功能期长,抗青秕,籽粒饱满,落黄好。该品种株高90~105 cm,白穗,长芒,芒色在灌浆中后期逐渐转为黑色,穗粒数36~45粒,籽粒白色,角质,千粒重45~55 g。该品种适宜在甘肃中部地区、甘南州,宁夏自治区隆德、西吉县,青海省民和县、西宁市和内蒙古等地的水、旱地种植。 |

| Dingfeng No.9 is a new variety of spring wheat that has been bred by Dingxi Dry-farming Research Center.It was selected by using the F1 generation of the cross combination "07802 Zhong/81194" as the female parent,and "630" as the male parent.The results of regional test have showed that Dingfeng No.9 is a variety with high yield,high resistance to diseases and high quality;The average yield of Dingfeng No.9 is 5010.3 kg/hm2,being 15.99% higher than that of the contrast Ningchun No.10;The content of crude protein,lysine and amylum in the grains is 17.73%,0.58% and 58.56% respectively;The roots are well-developed,the function period of leaves is long,and the seeds are plump;The plant height is 90~105 cm,the grains per spike is 3645,and the 1000-grain weight is 45~55 g. It is suitable to cultivate in irrigated or dry lands in central and southern Gansu,Longde and Xiji County in Ningxia,Minhe County and Xining City in Qinghai,and Inner Mongolia,etc. |
