摘要:

种业是农业发展的“芯片”,原始创新是农业可持续发展的根本动力。2021年中央一号文件明确提出推进中国农作物种业快速发展的要求,对中国农作物种业原始创新研究提出了明确期望。谷子是中国起源的传统粮饲兼用作物及特色杂粮作物,生产及消费规模均位居世界首位。作为粟类作物,谷子在中国农业生产及农耕文明的起始与发展过程中发挥了重要的推动和支撑作用,已有研究证实谷子在中国拥有悠久的栽培历史,并且形成了分布广泛且多样性丰富的各类种质资源。近年来,谷子在杂交品种选育及杂种优势利用、抗除草剂品种和适于机械化栽培品种推广、基因组学及功能基因研究等领域取得进展,在原始创新的推动下初步形成了以杂交品种和抗除草剂品种为经营主体的谷子种业体系,推动了谷子种业从无到有的突破。中国在谷子优异种质鉴定与创制方法研究、谷子高效育种技术途径研发、谷子关键性状的协调表达与调控规律解析、谷子良种繁育过程基本生物学属性研究以及谷子新品种真实性鉴定方法探索等方面原始创新的进步为谷子种业发展提供了支撑,形成了一套初具规模的种业原始创新技术。目前,谷子种业持续良性发展仍然面临包括优异突破性种质匮乏、育种技术水平相对滞后、品质与产量协调性不够、良种扩繁标准缺乏以及种业市场监管手段有待加强等诸多挑战。为了推进谷子种业持续快速、高效、深入的发展,未来中国谷子种业原始创新研究的主要方向包括:基于表型组学与基因组修饰技术、单倍体育种与全基因组选择技术和关键性状优异单倍型鉴定与整合技术的谷子规模化高效育种技术体系构建;基于种子发育生理调控、分子指纹及杂种优势高效利用技术的谷子种子高效生产储藏与监管技术体系构建;以及基于谷子种业产学研推一体化设计与高效整合的人才培养与创新体系构建等方面。

Abstract:

Seed industry was the ‘chip’ of agricultural development, and original innovation have played essential roles in maintaining stable development of modern agriculture. The No. 1 central document of China released in 2021 has put forward requirements of original innovation researches essential for supporting further developments of Chinese crop seed industry. Foxtail millet is a traditional crop species cultivated for both forage and grain food consumption in China, and to date, foxtail millet was still widely planted as minor cereals in China with the largest scale of field production and commercial consumption across the globe. Foxtail millet was originated from China and cultivated for thousands of years to ensure development of Chinese agricultural culture and field crop production. Original innovation in foxtail millet has promoted initial development of foxtail millet seed industry based on operation of herbicide-resistant varieties in recent decades, including breakthroughs in areas of heterosis utilization, herbicide resistant breeding, dwarfing variety creation and genomics study of this important crop species. Achievements of fundamental researches including germplasm characterization, development of breeding tools, coordination and regulation of vital traits, seeds propagation and truth identification of commercial varieties have provided more opportunities for further development of the seed industry of foxtail millet. However, challenges of seed industry development still exist in China, including deficiency of excellent germplasms, backward breeding approaches, inharmonious of yield and quality characters, unclear criterion of seed propagation and market supervision problems. Future direction of original innovation studies related to foxtail millet seed industry were as follows: 1) Large scale breeding systems constructed from utilizations of crop phenomics and genomic modification technologies, double haploid breeding and genome selection tools, identification and pyramiding of superior haplotypes; 2) Seeds production, store and quality supervision systems constructed from techniques of development and water content of commercial seeds, and establishment of molecular fingerprints and efficient utilization of heterosis in foxtail millet; 3) Construction of innovation system through integrating education, research and promotion sectors of seed industry and stimulate personnel training in China.
