Genetic Analysis of Nitrate Content in Radish(Raphanus Sativus L.)
摘要
Abstract
Genetic analysis was conducted on nitrate content of multiple generations (P1,F1,P2,B1,B2 and F2),derived from a cross between L0908 with lower nitrate content and L0915 with higher nitrate content,using the method of major gene + polygenes mixed inheritance model.The results showed:the optimum model of nitrate content was two additive-dominant-epigenous major genes + additive-dominant-epigenous polygenes rnixed inheritance model (E-0).Additive effect of the first and second pairs major gene were-682.293 and-27.938 and dominant effect of the first and second pairs major gene were-424.058 and-428.376,respectively,both had negative effect.The major gene heritability were 26％,37.5％ and 46.1％,the polygene heritability were 3.2％,11.7％ and 0％ and the environment heritability were 60.8％,50.8％ and 53.9％ in the B1,B2and F2 populations,respectively.The above results showed that the nitrate content was controlled by two major genes plus polygene,but the influence of environment was relatively great.关键词
