Correlation matrix wheat (Triticum asetivum L.) grain zinc (Zn) & iron (Fe) and among yield contributing traits quantitative and quality traits

Abstract

Micronutrient deficiency affects two-third of human population in the world. Micronutrient malnutrition is a serious issue now a day’s especially in developing countries. One of the several strategies to reduce the micronutrient deficiency by the quality breeding approaches. One of the strategy was to find out genetic variation for yield contributing traits and it was correlated with micronutrients such as zinc (Zn), iron (Fe). In the current research was conducted to find out the correlation between the high yielding contributing traits and micronutrients such as iron and zinc. So we can improve both seed yield with seed micronutrients. Highly significantly correlation was found between the seed yield for plant with days to maturity(r=0.307**, p<0.01) and test weights (r=0.558**, p<0.01). It means the maximum magnitude in yield component traits by days to maturity and test weights and trait more number of grains per spike. Highly significant correlation was found between mean values of iron (Fe) with days to maturity (r=0.357**), test weights (r=0.343**) and seed yield per plant (r=0.279*). We were also find the mean value of zinc (Zn) correlated with the yield per plant (r= -0.216*). So we can improve lines with high yield per plant and high iron and zinc simultaneously and no significant correlation with other yield contributing. It was suggested that high micronutrient concentration not necessary tensed to produce low yield lines. We will also use this relationship for biofortification when dealing with wheat varieties.
