为选育出能在黑龙江省高寒地区安全越冬的冬小麦品种,从1994年开始进行了冬小麦抗寒育种工作和保护越冬的栽培技术研究。由于冬麦抗寒性属于数量遗传性状,因此选用抗寒较强的品种间杂交和多亲本杂交,以利于抗寒基因累加和超亲遗传。几年来共杂交471个组合,于2002年从Norstar×(牡引88-13×Alabaskaja)组合中,选育出一个抗寒高产的新品系(东农024)。后经四年区域试验和生产试验,并结合保护越冬栽培措施,不论雪大或雪小年份都能安全越冬。2007年1月通过黑龙江省农作物品种审定委员会审定,正式命名“东农冬麦1号”开始推广,成为有史以来第一个能在黑龙江省高寒地区越冬的冬小麦新品种。
In order to breed winter wheat varieties that can win safely in the alpine region of Heilongjiang Province, the winter wheat breeding work and the protection winter cultivation techniques have been carried out since 1994. Cold-resistant winter wheat is due to the number of genetic traits, so the selection of strong cold-resistant cross between varieties and multi-parent cross, in order to facilitate gene accumulation and super-progeny genetic cold resistance. In recent years, a total of 471 combinations were obtained. In 2002, a new line with high cold tolerance and high yield (Dongnong 024) was bred from a combination of Norstar × (Mudou 88-13 × Alabaskaja). After four years of regional tests and production tests, and in combination with measures to protect overwintering cultivation, winter can be safe and winnable, regardless of snowy or snowy years. In January 2007, it was approved by Heilongjiang Province Crop Variety Approval Committee and officially named “Dongnong Dongmai 1” to be promoted as the first new winter wheat variety that can winter in the alpine region of Heilongjiang Province in the history.
