大麦与谷类科学

重点围绕丰产、稳产、抗病、早熟的育种目标，以广适丰产的20005为母本，以综合抗病性较好、熟期较早的冬A4为父本杂交，采用系谱法选育而成半冬性小麦新品种连麦11，推荐参加江苏省淮北小麦区域试验。区试结果表明，该品种平均单株分蘖数为6.33，成穗率为38.85%，均高于对照品种淮麦20（平均单株分蘖数为6.23，成穗率为38.25%），生育期较对照品种短0.8 d，熟相好。本文重点介绍连麦11的特征特性、产量表现和高产栽培技术。

Aiming to breed new wheat varieties with a high-yielding ability,yield stability,early maturity,and disease resistance,the wheat variety 20005 with a high-yielding capacity and wide adaptability had been used as the maternal parent and the wheat variety Dong A4 with early maturity and strong disease resistance as the paternal parent;consequently,the new semi-winter wheat variety Lianmai 11 was bred by systematic selection.The results of the variety regional trial showed that Lianmai 11 had 6.33 tillers per plant and the ear-bearing tiller percentage of 38.85%,both higher than those of the control wheat variety Huaimai 20 which had 6.23 tillers per plant and the ear-bearing tiller percentage of 38.25%.Lianmai 11 also showed fine maturity performance,having a shorter growth period by 0.8 day than Huaimai 20.This paper mainly introduces the characteristics,yield performance,and key cultivation techniques of Lianmai 11.
