Abstract

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.
