摘要
[目的]选育产量、米质和抗性相协调的香型优质水稻新品种.[方法]利用亲本间的遗传多样性和农艺性状的互补性,以高产、高配合力的父本福恢 669与香型、优质、抗病的不育系野香A杂交,结合多生态点抗性鉴定、高温逼熟后品质分析、多年多点品比试验等相结合.[结果]选育出优质、高产、抗病,株叶态协调的杂交稻品种野香优 669.2019-2020年参加福建省中稻区域试验,全生育期两年平均 139.8 d,比对照Ⅱ优 3301早熟 1.1 d,产量平均 9363 kg·hm-2,比对照增产 2.24%,未达显著水平.两年稻瘟病抗性鉴定综合评价为抗稻瘟病,稻米品质达部颁一等优质食用稻品种品质标准,2021年通过福建省农作物审定委员会审定(闽审稻 20210014).野香优669聚合了来自双亲的 22个有利基因,其中 6个为单方携带,16个为双亲均携带.[结论]野香优 669产量高、抗性强、品质好、口感佳,在生产上大面积推广应用,是福建省农业主推品种之一.
Abstract
[Objective]An aromatic,high-quality,high-yield,disease-resistant rice variety was bred.[Method]Utilizing the genetic diversity and complementing agronomic traits between the male parent,Fuhui 669 with high yield and combining ability,and the female parent,the fragrant,high-quality,disease-resistant sterile line Yexiang A,a new breed of rice were generated.The hybrid was subjected to multiple ecological resistance identification,a quality analysis after high temperature maturation,and years of multi-point comparison test prior to final selection.[Result]The high-quality,high-yield,disease-resistant Yexiangyou 669 of a desirable plant type was obtained and submitted to the regional trial for mid-season rice in Fujian from 2019 to 2020.In the 2-year trial,it showed an average growth period of 139.8 d,which was 1.1 d shorter than the reference cultivar,Ⅱ You 3301,and an average yield of 9363 kg·hm-2,which was 2.24%higher than control but not statistically significant.It exhibited resistance to rice blast and up to the national Grade A quality.In 2021,it was certified by the Fujian Provincial Crop Approval Committee as the Min Approved Rice No.20210014.Yexiangyou 669 had inherited 6 desirable genes from one parent and 16 common to both parents.[Conclusion]The new hybrid rice Yexiangyou 669 had high yield,strong disease resistance,and superb grain quality and was promoted as one of the main varieties in the province.
