国外引种在山东省小麦生产和品种改良中的作用

CONTRIBUTIONS OF INTRODUCING WHEATS FROM FOREIGN COUNTRIES TO WHEAT PRODUCTION AND VARIETAL IMPROVEMENT IN SHANDONG

自1949年以来,山东先后从50多个国家引进品种3000多个,直接或间接利用成效显著的有10余个。山东育成含早洋麦、早熟1号、欧柔、阿勃、St2422/464、1B/1R 抗病基因、兰科塔优质基因血缘的品种有30多个,在山东小麦生产和品种改良中发挥了重要作用。

Since 1949,over 3000 varieties of wheat have been introduced from more than 50 coun- tries.Over 10 of them produced marked effectiveness after direct or indirect using.More than 30 varieties selected in Shandong contained the disease-resistant genes of Early Premi- um(USA),(USSR),(Chile),Abbondanza (Italy),St2422/464 (I- taly) and 1B/1R,and Lancota's superior gene consanguinity(USA),which played an impor- tant role in wheat production and rarity improvement in Shandong.
