摘要
采用恢复系１９８与威２０Ａ配组育成的威优１９８，是一个中秆大穗、高产稳产、抗逆性强、米质优良的迟熟杂交晚稻新组合，已在生产上大面积示范推广，高产栽培技术及杂交制种措施已经配套．４年试验示范结果表明，威优１９８全生育期１２０～１２５ｄ，产量在９ｔ／ｈｍ２左右，米质达部颁二等优质米标准，中抗稻瘟病和白叶枯病，较抗纹枯病和褐飞虱，推广应用前景广阔．
Weiyou198,Wei20A/92 198(the restorer line 92 198,usually abbreviated to 198,is bred from the cross of the wide compatibility line DT713 and the restorer line Minghui 63),is a newly developed late hybrid rice combination with the characteristics such as:middle plant height and large panicle,high and stable yield,strong pest and stress resistance,and good quality. It has,till now,been commercialized in a wide range. Also,the technologies of high yield planting and hybrid breeding of the rice have come into maturity. A 4 year old experiment shows that Weiyou198 has a growth period of 120 days to 125 days. Its yield has reached 9 t/hm 2 more or less and its quality lives up to the high quality standard of the 2nd class which is a standard of the Agriculture Ministry of China. The popularization of the combination has a promising prospect.
