小麦不同类型品种的籽粒产量及品质在不同生态区的表现

PERFORMANCE OF GRAIN YIELD AND QUALITY OF WINTER WHEAT VARIETIES WITH DIFFERENT TYPE IN DIFFERENT ECOLOGICAL DISTRICTS

选用５种不同冬春性类型的１１个推广品种在省内４个生态类型区分期播种，研究不同类型品种在不同生态区的经济产量和籽粒品质。结果表明，不同类型品种在不同生态类型区的产量差异明显，适期秋播条件下，胶东丘陵区应以冬性品种为主，半冬性品种为辅；而鲁西南平原湖洼区，则应以半冬性品种和半冬性偏春性品种为主；鲁西北平原区和鲁中山丘川区适期早播时可种植冬性品种，适期晚播时可种植半冬性或半冬性偏春性品种。对供试品种籽粒品质的研究表明：小麦的籽粒品质与品种的冬春性似无直接关系，而与品种的遗传性有关。

The grain yield and grain quality of eleven varieties with different type in four ecological districts were studied under the condition of different sowing stage.The resutts showed that there was apparent difference in grain yield among the tested varieties in different ecological districts with the suitable sowing stage,the varieties with the feature of winter should be mainly planted and the varieties with the semi-winter feature coulod be selected to be subordinate varieties in jiaodong districts.The main varieties should be these with semi-winter feature in southwestern plain in Shandong.In north-western plain and central moutainous districst,the varieties with winter featture can be planted when earlier sowing within suitable sowing stage, and semi-winter variteies can be used when later sowing within suitable sowing stage.The study on the quality of grain showed that it has no relation with the winter or semi-winter feature of the varieties,but has close relation with its genetics, The grain quality in spring sowing is apparently better than that in autumn sowing.
