摘要
通过对16个多棱裸大麦品种的比较试验,从中筛选适宜沿海地区种植的高产、抗病多棱裸大麦品种。结果表明,在本地区,多棱裸大麦种植以抗倒抗病性较好、穗数600万～750万·hm-2、千粒质量25g左右、中早熟的多棱裸大麦为宜。在本试验中,以御岛麦、1972-5-5、苏72-44-16多棱裸大麦较适宜本地区种植。通径分析结果表明:多棱裸大麦高产品种,产量三要素要协调,应在保证足够穗数的前提下,适当提高千粒质量和穗粒数。
Comparison test of 16 multiple row naked barley varieties were studied in order to screen the high yield and disease resisted multiple row naked barley varieties which were suitable for coastal areas. The results showed that the multiple row naked barley vari- ety with better lodging resistance and disease resistance, 6-7.5 million of spike number per hectare, 1000-grain weight about 25 g, and middle-early maturity were suitable for this areas. In this test, the Yudaomai, 1972-5-5 and Su72-44-16 naked barley varieties were suitable for planting in this areas . The results of path analysis indicated that the three elements of yield should be coordinated, and ears should be enough to improve 1 000-grain weight and grain number per spike of multiple row naked barley varieties with high yield.
