Hermann Nilsson-Ehle Experiment In 1909, Ehle used grain color in wheat to test the concept that the cumulative effects of alleles at multiple loci produce the range of phenotypes seen in quantitative traits.

It also appeared that all alleles contributed equally in the production or absence of red pigment. The first experiment on polygenic inheritance was demonstrated by Swedish Geneticist H. Nilsson - Ehle (1909) in wheat kernels. Kernel colour is controlled by two genes each with two alleles, one with red kernel colour was dominant to white. He crossed the two pure breeding wheat varieties dark red and a white. In this paper, an analysis on Nilsson-Ehle’s hybridization experiment in wheat was done by means of self-fertilization method along with the pericarp inheritance. It showed that because seeds of wheat were coated with 2n tissues of mother’s body, the grain colors were determined by mother’s genotype.

One of the aim of experiment was to assess the influence of wheat cultivars on the relationship between chlorophyll content and nitrogen status in the leaf. In these investigations we confirmed a very close link between chlorophyll and nitrogen content in the flag leaf. This correlation was determined by Pearson (P e t z, 1985).

In other wheat varieties, Nilsson-Ehle found F 2 generations with a ratio of red kernels to white of 63:1. These could be explained by assuming that three pairs of alleles were involved. In these cases, six different shades of red could be detected, but the color differences were very slight.

A homozygous recessive plant (aabb) has white kernels. If you bred two plants that were heterozygous for both genes, what fraction of the offspring would you expect to have white kernels? 1/2 1/4 1/16 0 ABSTRACT: In this paper, an analysis on Nilsson-Ehle’s hybridization experiment in wheat was done by means of self-fertilization method along with the pericarp inheritance. It showed that because seeds of wheat were coated with 2n tissues of mother’s body, the grain colors were determined by mother’s genotype. The experiments described here sought to evaluate two methods of measuring preharvest sprouting susceptibility, color in wheat (Nilsson-Ehle.

Purple wheat lines exhibited higher peak intensities of acylated anthocyanidins. Chroma and hue values assisted in the efficient and reliable selection of compound grain colors. Cryo-microtome seed sections indicated presence of purple color in the pericarp all around the seed.
