摘要
应用灰色系统理论对天水地区8个参试品种产量与产量性状进行综合分析,结果表明,马铃薯产量与主要产量性状的关联度由大到小排序,次序为:单株块茎>株高>淀粉含量>大中薯个数比率>平均薯重>大中薯重量比率>分枝数。该结果对马铃薯育种目标的制定,品种改良具有实际意义。
Potato yield and character of yield was comhensively analyzed by gray system theory. The result was show： The connective degree order of main yield character and potato yield is tuber number of per plant, plant height, starchy content, percentage of big and middle tuber number, average tuber weight, percent of big and middle tuber weight and branch number.
