1971年,用中阿1号做母本St2422/464做父本进行杂交,经连续选育而成。株高86厘米,长方型穗,长芒、白壳、红粒、多花型,每穗40粒左右,千粒重40.6克。品质较好,蛋白质含量13.12%、赖氨酸0.26%。冬性,经过1976年严寒的考验,在北京地区能安全越冬。幼苗生长稳健蹲实,分蘖力中等,成穗率较高。杆硬弹性好,今年小麦灌浆期间曾多次迂暴风雨和冰雹,表现抗倒伏能力强。抽穗期比农大139早2天,后期落黄好,籽粒饱 In 1971, with China and Arab Republic No. 1 as female parent St2422 / 464 to do the male parent for crossbreeding, formed by continuous breeding. Plant height of 86 cm, rectangular panicle, Changmang, white shell, red, and more flowers, about 40 grains per spike, grain weight 40.6 grams. The quality is better, the protein content is 13.12% and the lysine is 0.26%. Winter, after the severe test of 1976, winter in Beijing can be safe. Squatting seedlings grow solid, medium tillering ability, ear higher rate. Rod hard elastic, wheat filling this year has repeatedly roundabout storm and hail, the performance of anti-lodging ability. Heading 139 days earlier than Nongda 139, late fall yellow, full of grain
