摘要: 总结高产、抗病杂交稻新品种广优673的选育过程及其主要特征特性。广优673系以恢复力强、恢复谱广、配合力好的恢复系福恢673为父本,以抗病不育系广抗13A为母本配制而成的杂交水稻新组合。该组合2011-2012年参加福建省中稻新品种区域试验,平均产量9 655.95 kg·hm-2,比对照Ⅱ优明86增产10.65%;2013年参加福建省中稻新品种生产试验,平均产量9 343.5 kg·hm-2,比对照Ⅱ优明86增产12.49%;在3年试验中表现高产稳产,全生育期143.2d,比对照Ⅱ优明86长1.1 d;经2年区域试验田间抗稻瘟病鉴定和室内接种鉴定,综合评价为中抗稻瘟病。该品种于2014年6月通过福建省农作物品种审定委员会审定。

Abstract: This article summarized the breeding process and main characteristics of a new hybrid rice variety, Guangyou 673. The hybrid was derived by crossing between the disease-resistant sterile line, Guangkang 13A, and Fuhui 673, which is a strong restorer line with broad recovery spectrum and good combining ability. It exhibited a mean yield of 9 655.95 kg·hm-2 at the regional trials in Fujian in two consecutive years, which was a 10.65% increase over that of the check variety, Ⅱ Youming86. In 2013,at the mid-season rice production test in Fujian, the mean yield of Guangyou 673 was 9 343.5 kg·hm-2, which was 12.49% higher than that of Ⅱ Youming 86.In 3 years of the regional tests,it showed a growing season of 143.2 d, which was merely 1.1 d longer than that of Ⅱ Youming 86.Over all, Guangyou 673 displayed the desirable traits of broad adaptability, high and stable yield during the trails, as well as of being medium resistant to blast by the indoor and field evaluations in two years. It was certified by the Crop Variety Approval Committee of Fujian, China in 2014.

Key words: hybrid rice, Guangyou 673, breeding, characteristics
