Variance analysis of kernel water content and dehydration rate at different maturity stages of maize hybrid
Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 2
Abstract
"Grain harvest mechanization will be developmental trend of maize production in the future， the moisture content and dehydration rate of grain in mature period are important factor to decide the mechanized harvesting. In this study，we used 86 different maize hybrid combinations as experimental material，measured moisture content of corn grain by the instrument measuring and drying method，analysis of different hybrid combination of corn varieties of grain moisture content and dehydration rate were differences. The results showed that the standard curve of the regression curve of the instrument and the drying method was y = 0.4445x + 14.603（R2 = 0.4509）. The moisture content of seed grains of different corn varieties was different，and the water content of seed grains such as Nong 422，Nong 853 and Nong 826 is about 25%. The rate of dehydration of different maize hybrids was significant，with the rate of dehydration at the fastest rate of Nongdan476 at 0.94% and the rate of dehydration rate of Nongdan584 at 0.11%. Different hybrids in the mature period of grain moisture content have significant advantages，breeding varieties to choose single 826，farmers kiss little advantage in 605，single species，and the general effect higher than that of male parent，female parent water content priority maternal low moisture content of varieties. This study suggests that the varieties of corn varieties，such as agricultural single 528，Nong 856 and Nong 154，will be tested，and the yield of maize varieties can be harvested from high yield and suitable grain."
