Analysis of Major Gene+Polygene Mixed Genetic Model of Grain Dehydration Rate in Spring Maize
摘要
Abstract
[Objective]In order to explore the genetic law of grain dehydration rate of spring maize.[Method]Six generations of P1,P2,F1,F2,B1 and B2 were constructed by using two varieties NP118 and MO17 with large differences in dehydration rate as parents.The genetic model analysis of grain dehydration rate was carried out by the main gene+polygene mixed genetic model analysis method.[Result]The average de-hydration rate of F1 generation in reciprocal cross was the fastest,and the F2 generation population showed a continuous approximate normal dis-tribution,which was consistent with the characteristics of quantitative traits.The best genetic model of spring maize kernel dehydration rate was additive-dominance-epistasis(PG-ADI)polygene genetic model.The non-additive effect plays a major role,and it is stably inherited in each segregating generation,and the environmental factors have little effect.[Conclusion]The study laid an important theoretical foundation for fur-ther mapping and mining the key genes controlling the grain dehydration rate of spring maize and breeding new varieties suitable for mechanized harvesting.关键词
