Influence of quality traits on green cob yield in hybrids of sweet corn (Zea mays L. saccharata)
Abstract
Seventy two sweet corn hybrids developed from eighteen sweet corn lines were studied for association between green cob yield and quality traits. The genotypic correlations revealed that the green cob yield had highest positive and significant correlation with green cob length followed by green cob girth, number of kernels per row, plant height, leaf length, leaf breadth, number of kernel rows per cob, number of leaves, non reducing sugar and total sugar. Days to 50 per cent tasseling, days to 50% silking and days to green cob harvest recorded significant and negative association with green cob yield. The inter association among quality traits showed that total soluble solids recorded positive relationship with total sugar and total sugar had negative association with starch.
