经过多年重复品比、区试直至鉴定而通过的优良甘蔗品种往往累积了大量的数据资料。但是,通常育种工作者只利用这些数据资料作为直观反映了该品种的性状及其丰产性能。其实,这些试验数据资料也给我们提供了构成甘蔗单位面积产量的3因子(株高、茎径和有效茎数)之间的相互关系.及其这3个因子对产量贡献大小的信息。我们 After many years of repeated product ratio, the regional test until the identification and adoption of good sugarcane varieties often accumulate a large amount of data. However, it is common for breeders to make use of these data as an indicator of the variety’s traits and its high yields. In fact, these experimental data also give us the correlation between the three factors (plant height, stem diameter and number of effective stalks) that make up the yield per unit area of ​​sugarcane and the information on the contribution of these three factors to the yield. we
