【摘要】 本文介绍了一种在实生苗世代准确测定和筛选高淀粉材料的有效方法——株系系统测定筛选法.此法通过对实生苗单株块茎淀粉含量的系统测定和统计,得到单株块茎淀粉含量的平均数、变异幅度和上下限,最后以所得数据的综合分析结果作为依据,准确筛选高淀粉材料.连续几年的试验结果证明这种方法可行、有效.更多还原

【Abstract】 An effective method for deteetion and screening of the materials with high starch content in seedling populations was introduced in this paper.The method can be summarized as follows: The seedlings with such characteristics as resistance to diseases, high yield and shallow eyes were selected, and all of the tuberes, instead of one tuber, per seedling were measured for their starch content, then the arithmetic mean and maximum of starch content in the tubers per seedling were significantly correlated to the arithmetic means of tubers in its first and second year clones, therefore the arithmetic mean and maximum of starch content in tubers per seedling can be used as a standard for selecting the materials with high starch content in potato breeding.更多还原
