中文摘要:
      Super maize was a science and technology innovation for enhancing maize cultivars yield ability on the basis of maize heterosis utilization at present.This paper discussed the significance of super maize breeding,indicating that the objective of super maize should consider the approved efficiency of cultivar,the character of high yield and stable yield and the determination of yield index in high yield tackling field,except"super high yield,high-quality,multi-resistant,wide-suitable,easy production of seed",also proposed higher requirements for germplasm-innovation,plant type selection and plant characters.Aiming at present status of super maize popularization,suggesting that we should accelerate to establish reginal trial appoved criteria,pay attention to finy varieties with suitable cultivation method,high-yield demonstration and high-yield tackling trial.
英文摘要:
      超级玉米是在目前玉米杂交优势利用的基础上,以提高玉米品种单产能力为目标的科技创新。本文论述了超级玉米育种的意义,指出超级玉米的选育目标除"超高产、优质、多抗、广适、易制种"外,还应考虑品种的审定效率、高产稳产性、高产攻关田产量指标,并对种质创新、株型选择、植株性状提出了更高的要求。针对超级玉米推广的现状,提出了加速制定超级玉米品种区试审定标准、注意良法配套和高产示范、重视高产攻关试验的建议。
