Longdao 22 is Heilongjiang Academy of Agricultural Sciences Institute of cultivation and cultivation of new rice varieties. With Wuyoudao 1 as female parent and Longjin 1 as male parent, its hybrid offspring was bred by pedigree selection and ecological selection. In 2004, F_0 generation was obtained through crossbreeding and hybrid seeds were harvested. Hybrid seeds were planted in F_1 generation in 2005, and from 2006 to 2009, pedigree lines were planted to F_5 generation. In 2010, the stable F_5 generation Planting was F_6 generation, at the same time, disease resistance, lodging resistance, yield, quality and other testing, of which one of the best strains to elect. From 2011 to 2012, he took part in the regional trial of the first accumulated temperate premature in Heilongjiang Province, and from 2013 to 2014 participated in the production test of the first accumulated temperate premature in Heilongjiang Province. In May 2015, it was approved by Heilongjiang Crop Variety Approval Committee, and its validation number is Heishao 2015018.
