在选育杂交高梁的初期,是直接利用具有恢复性的高粱品种与雄性不育系杂交配制杂种。为了选育产量更高而品质又好的杂交高粱,目前是将杂交高粱新组合选配与高梁杂交育种结合起来进行的。即首先利用杂交育种方法,选育新的不育系和恢复系,然后来配制杂交高粱。在当前,普遍采用了类型间杂交,如为选育新的恢复系,常采用中国高粱×亨加利高粱;为选育新的不育系,多采用南非高粱×中国高粱、西非高粱×中国高粱。上述表示,包括正、反交,以
In the early breeding hybrid sorghum, sorghum is directly used to restore sexual sorghum hybrids and male sterile lines hybrids. In order to breed hybrid sorghum with higher yield and better quality, the combination of the new combination of sorghum and cross sorghum breeding is currently being carried out. That is, the first hybrid breeding methods, breeding new sterile lines and restorer lines, and then to prepare hybrid sorghum. At present, it is common to use cross-type hybridization. For example, new sorghum × Hengali sorghum is often used for breeding new restorer lines. For breeding new sterile lines, sorghum × sorghum × sorghum × West China Sorghum The above said, including positive, anti-cross, with
