一、甘蔗强化育种的理论基础甘蔗品种的改良,不断增加新的“种”质是重要的途径。种内品种间杂交由于所产生的变异不大,因此,育种的成就很有限,甘蔗育种的历史已证明了这一点。印度用热带种与野生种杂交育成抗病力强产量高的杂种印度291和印度206。Kobus用蔗糖产量高而易感矮化病的热带种黑车里本与蔗糖份低抗矮化病的印度种春尼杂交育成的爪哇213和234,其抗病力 First, the theoretical basis of sugarcane enhanced breeding Sugarcane varieties improved, increasing the new “species ” quality is an important way. Because of the small variation in crossbreeding among varieties, the success of breeding is limited and the history of sugarcane breeding has proved this point. India uses hybrids of tropical and wild species to breed hybrids with high disease resistance India 291 and India 206. Kobus was resistant to disease by using Java 213 and 234 grown in a tropical black car with a high sucrose yield and susceptible to dwarfism, grown in India with a low resistant to sucrose
