‘Yujiucong No.1' is a new variety bred by systematic selection from mutant population of ‘Changbaishanxidasuan' through 4 generations of selfing.The variety has compact plant type and erect leaves folded into "V" shape.It has 6-8 functional leaves during growing stage.This variety is 60-80 cm in plant height,false stem segment is 20-30 cm in length,its stem thickness is 1.5-2.0 cm,and white stem length is less than 5 cm.The single plant weight is 65-90 g.Its resistances to gray mould,loemia,rust and purple blotch are stronger than that of the contrast ‘Lyucui' and ‘Changbaishanxidasuan'.It can yield about 75 t · hm-2.It is suitable to be cultivated in central Yunnan Province and regions with similar climatic conditions all year round in open fields.
