一、意义不同高粱类型之间的育性表现有很大差别。西非、北非、中非、印度的高粱多属恢复或大半恢复类型;亨加利高粱全部为恢复类型;南非高粱多属保持类型;只有中国高粱品种类型复杂,从全保到全恢,各种育性都有。我国的高粱育种经验证明,大多数杂交高粱的优良组合是由南非、中国、亨加利三种类型互相杂交组配而成。而亨加利类型及其F_1在不同光照条件下生育期变化很大,直接应用有局限性,所以影响了它的推广和应用范围。而由南非高粱、中国高
First, the significance of fertility between different types of sorghum performance there is a big difference. Most of the sorghums recovered or mostly recovered in West Africa, North Africa, Central Africa and India; all of the HENGARI sorghums were of the recovery type; most of the sorghums in South Africa were of the preserved type; only the types of sorghum in China were complex, ranging from full protection to full recovery. Fertility has. The experience of sorghum breeding in China proves that the fine combination of most hybrid sorghums is formed by the hybridization of three types of South Africa, China and Henggali. However, the type of HENGALI and its F 1 varied greatly during the growth period under different light conditions, which had limitations for its direct application, thus affecting its popularization and application. And by South Africa sorghum, China high
