杂交水稻珍汕97不育系繁殖,常受气候因子的影响,导致高产年分种子积压,低产年分种子不足。为了弥补因自然条件造成的缺陷,解决不育系繁种产量年度之间的不平衡;摸索不育系的繁种减少代数,保持种性,必须进一步测定珍汕97不育系和国际26新、陈种子配制成汕优六号的杂种优势,及其在生产上利用价 The hybrid rice Zhenshan 97 CMS breeding, often affected by climate factors, resulting in high-yielding annual seed backlog, low-yielding seed points. In order to make up for the deficiencies caused by natural conditions, to solve the imbalance between the annual yield of sterile lines; to explore the breeding of sterile lines to reduce the algebra, to maintain the nature, we must further determine Zhenshan 97 sterile lines and international 26 new , Chen seed preparation Shanyou 6 heterosis, and its use in the production price
