Twelve varieties each of barley and wheat and 10 of soybeans were grown in 2 years at two locations to assess genetic and environmental variation in accumulation of 12 mineral elements. Seedling leaves and seed of barley and wheat and seed of soybeans were assayed. Varietal differences in accumulation of P, K, Mg, Na, Ca, Mn, B, and Sr were significant in most plant materials studied. In contrast, differences in accumulation due to years and locations generally were small and non-significant.
A few of the genotype ✕ environment interactions were statistically significant but the majority of them were nonsignificant, and all the interaction components were smaller than the experimental error. Also, estimates of genetic variane were larger generally than interaction components. The consistency in performance of genotypes across years and locations indicates that a single environment may suffice when screening genotypes for differences in mineral accumulation.
Genetic correlations involving accumulation of a particular element in seed and seedling leaves were positive and near 0.4 to 0.5. Ca and Sr accumulation were highly correlated in all plant materials. In soybean seed, P, Ca, Sr, Mg, and Mn accumulations were highly and positively correlated.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
