利用1990～1991年夏棉黄河流域区试、省区试、生产试验及株系考种资料,对夏棉新品系豫早1109的皮棉产量及各产量因素进行了相关分析、回归分析和通径分析,并对其皮棉产量进行数学模拟,得出各种产量结构,提出了相应的高产措施。
The correlation analysis, regression analysis and path analysis of lint yield and yield of a new summer cotton cultivar “Yu-wei 1109” were carried out by using the regional test, the provincial test, the production test and the test data of summer rapeseed from 1990 to 1991. Analyzes and simulates the lint yield, obtains various output structures and puts forward corresponding high yield measures.
