摘要
利用先进的直链淀粉自动分析仪，普查黑龙江省９２份现种植品种（系）及保存材料的直链淀粉含量，了解总趋势，其平均值为１９．０％；直链淀粉含量达到国家二级优质米标准的占５８．７％；从后备材料中筛选出这样的材料２２份；同时对影响直链淀粉含量的气象和栽培因素进行了初步研究。
Straight chain Starch Auto analysis Instrument was adopted in this study to examine the content of straight chain starch of 92 varieties or strains of rice which growed and reserved in Heilongjiang. The general trend was learned from this study. The average content of straight chain starch of all the materials is 19.0 per cent. There are 58.7 per cent materials whoes contents of straight chain starch reach the Country Second Quality Rice Standard. Twenty two such materials were selected from the reserved varieties. At the same time weather and cultural factors which affect the content of straight chain starch were studied.
