Screening and Evaluation of High Starch Maize Varieties in Heilongjiang Province
摘要
Abstract
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.关键词
