粒用高粱;矮秆耐密;广适性;繁殖推广体系
摘  要：
粒用高粱育种近10年来进展缓慢,今后应以高产为目标,以多抗、耐密、广适为核心,以优质为保障。(1)组织高粱育种单位、育种者之间进行科研大协作,加强基础研究,强化技术储备,重视农艺性状选拔,创造新种质;(2)适应气候条件变化,选择相对较晚熟的杂交种,有利于提高产量;(3)重视改善品质,根据用途培育优质高产杂交种;(4)提高抗逆性和耐密性,增强抗倒性;(5)不同类型间亲缘关系要清晰,以保持和提高两亲间的杂种优势;(6)改进和强化育种选择方式,增加F2代群体株数,保证种植密度,强胁迫环境下选择,提高选择强度;(7)改进和完善种子繁殖制种技术,保证新品种的繁制质量和数量,建立优良杂交种推广体系;(8)促进粮食转化,提高经济效益,利于高粱发展。

摘  要：
Grain sorghum breeding in the recent 10 years progress slowly, from now on will be supposed take the high production as the goals, by many anti-, will bear, Guang Shiwei densely the core, take high quality as the safeguard.(1) organization sorghum breeding unit, between the breeding carries on the scientific research large-scale cooperation, the enhancement basic research, the strengthening technological strength, takes the agronomic characters to select, creates the new idioplasm.(2) climatize condition change, the choice compares the late-maturing relatively the hybrid, is advantageous in enhances the output.(3) takes to improve the quality, according to use cultivation good quality and high output hybrid. (4) enhances the resistance and bears dense, strengthens anti-but actually. During during (5) different type the blood relationship relations must be clear, maintains and enhances two kisses the heterosis. (6) improvement and the strengthened breeding choice way, increases a F2 generation of community number, guaranteed the planter density, forces under the environment to choose, enhances the choice intensity.(7) improvement and the consummation seed reproduction breeding technology, guaranteed the new variety the numerous system quality and quantity, establish the fine hybrid promotion system. (8) promotion grain transforms, enhances the economic efficiency, favors the sorghum development.
