摘　　要：野香优633是福建省农业科学院水稻研究所以自育的优质、高产、抗病的恢复系福恢633为父本,以从广西绿海种业有限公司引进的优质、香型、抗病不育系野香A为母本杂交选育而成的三系晚籼杂交稻新品种,2023年通过福建省农作物审定委员会审定(闽审稻20230011)。野香优633产量高,两年区域试验平均产量为7648.5 kg·hm^(-2),比对照宜优673增产1.4%,生产试验平均产量为7609.5 kg·hm^(-2),比对照宜优673增产3.6%。经2年区域试验室内接种和田间稻瘟病抗性鉴定,结果为中抗稻瘟病,稻米品质达到部颁一等优质食用稻品种品质标准。野香优633米饭有茉莉香味,口感好,适合作高档优质稻栽培。介绍了野香优633的选育过程,并根据品种特性提出了主要栽培技术要点,以利于该品种在生产上的推广应用。Yexiangyou 633 was a new variety of three-line late indica hybrid rice which was cross bred by the Rice Research Institute of Fujian Academy of Agricultural Sciences,from Fuhui 633(a restorer line with high quality,high yield and disease resistance)as the male parent,and Yexiang A(a sterile line with high quality,flavor type and disease resistance introduced from Guangxi Lvhai Seed Industry Co.,Ltd.)as the female parent.It was approved by Fujian Agricultural Crop Approval Committee in 2023(Min Approved Rice 20230011).Yexiangyou 633 had high yield,the average yield of Yexiangyou 633 in the two-year regional test was 7648.5 kg·hm^(-2),which was 1.4%higher than that of the control Yiyou 673.The average yield in the production test was 7609.5 kg·hm^(-2),which was 3.6%higher than that of the control Yiyou 673.After 2 years of indoor inoculation in the regional test and the field resistance identification to rice blast,it was comprehensively evaluated as medium resistance to rice blast,and the rice quality could reach the quality standard of first-class and high-quality edible rice varieties issued by the Ministry.The rice of Yexiangyou 633 had the flavor of jasmine and good taste,which was suitable for the cultivation of high-grade and high-quality rice.The breeding process of Yexiangyou 633 was introduced,and the main cultivation techniques were proposed based on the variety characteristics,in order to facilitate the promotion and application of this variety in production.
