黑龙江省高淀粉玉米品种筛选与评价

摘要

In order to solve the problem of lack of high starch maize varieties and confusion of classification in Heilongjiang province, the high starch characteristics of 88 main maize hybrids in this area were screened and evaluated.The results showed that the average starch content was 73.32％.70 high-starch maize with starch content of 72％ or more were screened out, and the average starch content was 73.82％.The high starch level was 1;29 secondary varieties;40 varieties of grade iii.There were only 13 industrial high-starch maize varieties (crude starch content above 75％), which were distributed in each ripening group.Through the selection of high-starch varieties and their actual yield, the high-yield maize varieties in each ripening stage were evaluated, and the planting status of high-starch maize in Heilongjiang province was combined to provide research basis for the breeding of new high-starch varieties.%为解决黑龙江省高淀粉玉米品种缺乏及分类混乱的问题,对该地区88个主要玉米杂交种的高淀粉特性进行筛选与评价.结果表明:参试品种平均淀粉含量73.32％.筛选出淀粉含量≥72％的高淀粉玉米70个,平均淀粉含量73.82％.其中高淀粉一级为1个、二级品种29个、三级品种40个.工业专用型高淀粉玉米品种(粗淀粉含量在75％以上)仅有13个,分布在各个熟期组.通过对参选的高淀粉品种筛选结合其实际产量,评价各熟期组高产玉米品种.
