The Common

Magenta flower color in soybeans (Glycine max (L.) Merr.) was found to be controlled by a mutant gene, wm, in the presence of W1 which is the common gene for purple flowers. These two genes are closely linked (2.2 ± 0.7% recombination) and are members of what is proposed as Linkage Group 8. The wm reduces flavonol content of flowers and of leaves, and is a deleterious mutant in terms of photosynthetic rate and bean yield.

Male Sterility Gene

The F2 distribution of male sterility (ms1) and flower color (w1) in a cross between translocation 172-11-3 (W1W1Ms1Ms1) and A77-139 (w1w1Ms1ms1) in soybean, Glycine max (L.) Merr., was highly abnormal. Duplicate-deficient and 41-chromosome progenies constituted 32% of the F2 population. The w1, and ms1 loci are located on the translocation exchange chromosomes designated T1 and T2, respectively. Evidence from other translocations suggests that linkage group 8 (LG8) is located on the single satellited normal chromosome designated NI. The breakpoint lies between the ms1 and w1, loci with recombination values of 18.4 ± 3.3% and 2.0 ± 1.2%, respectively.Key words: linkage, translocation, soybean, Glycine.

In field experiments with young spaced plants of 48 soybean (Glycine max (L.) Merr.) cultivars, derived lines tended to have higher rates of apparent photosynthesis (PA) than their parent lines over 3 yr of tests using the 14CO2 method. For 2 yr in which chlorophyll and specific leaf weight (SLW) were also measured, a significant number of derived lines had higher PA, chlorophyll and SLW than their parent lines. With 12 cultivars of similar maturity, grown as row-crop tests for 4 yr, PA and leaf percent N were correlated with each other during August (pod-filling period) but not during July (flowering period). August PA and leaf percent N were correlated with bean yield, but July values were not. Chlorophyll and SLW were correlated with each other in July and in August; each was correlated with PA in July but not in August. Although July measurements of leaf characters were not correlated with bean yield, July and August values were correlated for PA and for chlorophyll. The correlations observed among the characters in different sampling periods are discussed in relation to possibilities for selection.

Biological Methods

The purpose of our study was to develop biological methods to protect soybean from pests. Lepidoptera is believed to be one of the most numerous groups of insects in this crop. As a conservative estimate, 20 species of Lepidoptera were found in soybean agrocenosis; the greatest damage to Glycine max L. caused Etiella zinkinella Tr. 1832 and Helicoverpa armigera Hb. 1805. It was shown that not less than 500 m distance of crops from the main reserve of pests – robinia and the use of early ripening varieties provided the minimum loss of bean yield (no more than 0.9 – 1.9%). The use of biological preparations based on B. thuringiensis – lepidocide and bitoxybacillin allowed reducing beans and seeds damage by pests by 20-30%.

Leaf N

Field experimentation with soybean (Glycine max (L.) Merr.) indicated that leaf N, photosynthetic rate (PA) and yield are correlated. The degree of association is not strong and heritability for leaf N is not markedly greater than for PA or yield. Therefore, selection for leaf N to improve PA and/or yield would not be an advantageous approach.Key words: Soybean, leaf N, photosynthesis, yield

Simple Sequence

Three lethal-yellow mutants have been identified in soybean (Glycine max (L.) Merr.), and assigned genetic type collection numbers T218H, T225H, and T362H. Previous genetic evaluation of T362H indicated allelism with T218H and T225H and duplicate-factor inheritance. Our objectives were to confirm the inheritance and allelism of T218H and T225H and to molecularly map the locus and (or) loci conditioning the lethal-yellow phenotype. The inheritance of T218H and T225H was 3 green : 1 lethal yellow in their original parental source germplasm of Glycine max 'Illini' and Glycine max 'Lincoln', respectively. In crosses to unrelated germplasm, a 15 green : 1 lethal yellow was observed. Allelism tests indicated that T218H and T225H were allelic. The molecular mapping population was Glycine max 'Minsoy' × T225H and simple sequence repeat (SSR) markers were used. The first locus, designated y18_1, was located on soybean molecular linkage group B2, between SSR markers Satt474 and Satt534, and linked to each by 4.4 and 13.4 cM, respectively. The second locus, designated y18_2, was located on soybean molecular linkage group D2, between SSR markers Satt543 and Sat_001, and linked to each by 2.2 and 4.4 cM, respectively.Key words: duplicate gene, Glycine max, homoeologous genomic segment, genome evolution, lethal-yellow mutant.

Seed Coats

Soybeans (Glycine max (L.) Merr.) with black seed coats and green cotyledons are rich in anthocyanins and chlorophylls known as functional nutrients, antioxidants and compounds with anticarcinogenic properties. Understanding the genetic diversity of germplasm is important to determine effective strategies for improving the economic traits of these soybeans. We aimed to analyze the genetic diversity of 470 soybean accessions by 6K single nucleotide polymorphic loci to determine genetic architecture of the soybeans with black seed coats and green cotyledons. We found soybeans with black seed coats and green cotyledons showed narrow genetic variability in South Korea. The genotypic frequency of the d1d2 and psbM variants for green cotyledon indicated that soybean collections from Korea were intermingled with soybean accessions from Japan and China. Regarding the chlorophyll content, the nuclear gene variant pair d1d2 produced significantly higher chlorophyll a content than that of chloroplast genome psbM variants. Among the soybean accessions in this study, flower color plays an important role in the anthocyanin composition of seed coats. We provide 36 accessions as a core collection representing 99.5% of the genetic diversity from the total accessions used in this study to show potential as useful breeding materials for cultivars with black seed coats and green cotyledons.
