Environmental Stability Analysis of Quality Traits in Heinong 84
Aiming to identify environmental stability and provide a basis for the promotion and application of the new variety,we studied the quantity traits of Heinong 84 in nine locations in Heilongjiang province.The research have shown that Heinong 84 has higher protein content,lower oil content,higher linolenic acid content,higher sucrose and lower stachyose content.The coefficients of variation of 16 quality traits(protein content,oil content,oil plus protein,palmitic acid,stearic acid,oleic acid,linoleic acid,linolenic acid,tocopherol,soluble sugar,γ-tocopherol,δ-tocopherol,fructose,glucose,sucrose and stachyose)are less than 10％,which are stable.The variation range of the genetic diversity index in the two years was 1.08-1.98 and 1.07-1.73,with an average value of 1.62 and 1.59,respectively.The genetic diversity index of α-daidzein was the highest(1.98 and 1.73)and raffinose is the smallest(1.08 and 1.07).The quality traits of Heinong 84 can be divided into two categories:One is higher protein content and α-tocopherol,lower oil content and isoflavone,another is lower daidzin,m-daidzin,α-daidzin and m-genistin.The environmental stability of Heinong 84 provides a theoretical basis for the genetic breeding and processing of the variety.
