大多数现有的甘蔗品种是杂交产生兼进行无性繁殖的。由于选种是根据总的遗传变异而进行的,所以,这种育种方法为甘蔗选种提供了有利条件。遗传的总表现型的变异率可借助遗传力来测定.对无性繁殖作物的遗传力进行估算的各种方法已有介绍.Shah估算了6个性状的广义遗传力——发芽数和速度、株高、分蘖数、绿叶数和叶宽,它们在甘蔗育种中也许是重要的。Rao等也报道了构成甘蔗产量和质量的某些经济
Most existing varieties of sugarcane are hybridized and cloned. Since selection is based on total genetic variation, this breeding method provides favorable conditions for the selection of sugarcane. Variability in inherited total phenotypes can be determined by heritability Various methods for estimating the heritability of cloned crops have been introduced.Shah estimates the general heritabilities of the six traits - germination number and speed, strain High, number of tillers, number of green leaves and leaf width may be important in sugarcane breeding. Rao et al. Also reported on some of the economies that make up sugar cane production and quality
