温带甘蔗有性杂交育种,是一个牵涉面较广、难度较大的复杂问题,目前主要存在两种不同的看法:一认为温带甘蔗生长期短,冬、春季温度太低,不宜搞有性杂交育种,抑或个别年份有部份材料抽穗开花,经杂交后可以得到一些种子并能发芽成苗,但要定向杂交也是枉然;二认为虽有不利因素,但只要通过科学试验,耐心细致摸出它的主要规律,控制不利因素,发展有利因素,变不利为有利,则温带甘
Sexual crossbreeding of temperate sugarcane is a complex and complicated problem involving a wide range of issues. Currently, there are mainly two different opinions. One is that sugarcane has a short growth period, temperatures in winter and spring are too low, and it is not appropriate to engage in sexual crossbreeding Breeding, or individual years, some materials heading flowering, after the hybrid can get some seeds and germinate into seedlings, but the targeted hybridization is in vain; Second, despite the unfavorable factors, but as long as through scientific experiments, carefully nurtured it out The main law, control unfavorable factors, the development of favorable factors, become unfavorable for the benefit, then temperate
