玉米新品种锦单18号是由锦州农科院于2003年以自选系Z08为母本,Z23为父本组配而成的单交种。2008年经辽宁省农作物品种审定委员会审定,审定编号为辽审玉(2008)363号。经过几年的推广,证明锦单18号是一个优良的中晚熟玉米新品种,具有高产、高抗、活秆成熟等优良性状,推广前景广阔。但是,制种产量低一直是它本身的一个弊端,制约着锦单18这个较优良品种的推广。针对这个问题,摸索并总结了一套新的制种经验——反交制种技术,这可以大大提高制种产量。
Maize Jindan No. 18 is a single cross between Jinzhou Academy of Agricultural Sciences in 2003 with the optional Z08 as the female parent, Z23 paired with the parent. In 2008 by the Liaoning Provincial Crop Variety Approval Committee validation, validation number for the Liao Jade (2008) No. 363. After several years of promotion, it was proved that Jindan No.18 is a fine middle-late maturing new maize variety with excellent characters of high yield, high resistance and mature stalk and so on. However, the low seed production has always been a drawback of itself, restricting the promotion of this relatively fine variety 18. In response to this problem, explore and summarize a new set of seed production experience - anti-cross breeding technology, which can greatly improve the seed production.
