Title: Yield Indicating Traits Analysis of Maize Hybrids
Abstract: crosses and reverse crosses were made according to NCII genetic mating design.After they had been planted with random blocks,analysis of genetic correlation,linear regression and path coefficient were conduct-ed to16traits which constitute the yield or related with it.The results indicated that the genetic correlation coeffi-cients are all positive between grain yield and ear position,plant height,ear position/plant height,ear length,ear width,length of the ear with kernels,ear rows,kernels per row,hundred kernel weight,kernel length,kernel length/width.All of those correlation were extremely significant in statistic except the one between yield and ear rows.On the basis of their determining coefficients,the rank of importance for the16yield related traits was as follow:ear lengthkernel lengthear widthkernels per rowlength of ear with kernels ear insertionhundred kernel weightear rowsunit weightleaf anglekernel thicknesskernel widthkernel ratiokernel lengthear posi-tion/plant heightplant height.The upper7important traits were chosen to built a regression equation which could be as a indicative character for yield selection in Northern spring sowing maize zone.
