摘　　要：云粳37号是以具有香味且表现高产稳产的粳稻品种云粳26号作母本,以持有低直链淀粉含量调控基因Wx^(y37)且稻米食味品质优异、耐寒性和抗病性强的粳稻软米品种银光作父本杂交育成,具有食味品质优异、高产、稳产、耐寒、抗病等优良性状。通过对云粳37号及双亲全基因组重测序和功能基因优势等位基因型分析发现,云粳37号遗传了双亲的多个优势等位基因,如香味基因Badh2、抗稻瘟病基因Pi35、调控低直链淀粉含量基因Wx^(y37)、耐冷基因CTB4a、抗旱基因OsPP15和抗白叶枯病基因Xa26等,是目前云南省影响较大的粳稻品种。Yunjing 37 is a aromatic soft japonica rice variety,which was bred by using Yunjing 26 with high and stable yield as maternal parent and Yinguang with good eating quality,cold tolerance and disease resistance as paternal parent.Yunjing 37 has the characteristics of good eating quality,high and stable yield,cold tolerance and disease resistance,By resequencing the whole genome and analysis of its functional gene dominant alleles of Yunjing 37 and the parent,we found that Yunjing 37 inherited multiple dominant alleles from its parent,such as aroma gene Badh2,the rice blast resistance gene Pi35,the cold tolerance gene CTB4a,the drought resistance gene OsPP15,the bacterial blight resistance gene Xa26,as well as controling low amylose content Wx^(y37)alleles.Yunjing 37 is currently a highly influential japonica rice variety in Yunnan Province.
