水稻生育性状的遗传相关性及其对产量的贡献

利用Visual Basic语言编写应用程序,在计算机上对不同品种在同一栽培条件下水稻生育性状及产量指标独立变量作简单的相关和通径分析,并按对产量相对重要性较大的四个生育性状指标划分水稻品种的生育类型;同时,对同一品种在不同栽培条件下水稻生育性状及产量指标非独立变量作偏相关和偏回归分析,得出产量依穗数、粒数、结实率和千粒重的回归模型,并找出不同产量水平下的穗粒结构。

The Heredity Relevance and the Contribution to Output of Paddy Rice Birth Character

Compilating application procedure by using Visual Basic language,makes the simple correlation and passing the diameter analysis on the computer to the paddy rice birth character and the production target independent variable of the different variety under the identical cultivation condition,and according to four output relative importance birth character targets,divides paddy rice variety birth type.At the same time,makes the partial correlation and the regression analysis to the paddy rice birth character and the production target non-independent variable of the identical variety under the different cultivation condition,obtains the regression model on the output according to the number of ears, the number of seeds,the ratio of seeds and the weight of a thousand seeds,and discovers the yield structure under the different production level.
