近年来,随着甘蔗育种工作的需要,在相关分析的基础上进行了各产量组分对产量相对重要性的研究,如Miller和James(1974、1977),Balasundaram(1978)等把组成蔗茎产量和单位面积含糖量的最初组分——茎径、茎长、比重与中间组分——茎数、含糖率或锤度并列起来进行比较分析,其结果是茎数对茎产量、单位面积含糖量的作用最大,含糖率或锤度的作用较少或最少。日本永富成纪1979年在两地点的试验结果:一个是单茎重、有效茎数和可制糖率(C.C.S%)对可制糖量均具有相同(近似)的直接效应,而在另一个则对可制糖量的贡献以可制糖率(C.C.S%)为最突出,其次才是有效茎重和茎数。
In recent years, with the need of sugarcane breeding, the relative importance of yield components to yield has been studied based on the correlation analysis. Miller and James (1974, 1977) and Balasundaram (1978) Yield and the unit area of sugar content of the initial components - stem diameter, stem length, specific gravity and the middle component - the number of stems, sugar or brix together for comparative analysis, the result is the number of stalks stem yield, The largest unit of sugar content, the role of sugar or brix less or least. Japan Yongfu Chengji 1979 results at two locations: one is a single stem weight, the effective stalks and cans of sugar (CCS%) on the amount of sugar can have the same (approximate) direct effect, while in another The contribution to the amount of sugar can be the most prominent CCS%, followed by the effective stem weight and number of stems.
