“…Therefore variation/deviation from normal expression is not necessarily related to genetic variation. Rabel et al (2010) reported Satt070 present at B2 as a potent marker to distinguish soybean varieties based on hilum color. The working group of UPOV evaluated soybean seeds for variation in hilum color using variety CD 222 (black hilum) and CD 02RV-8444 and CD01RV-7618 (brown hilum) involving 16 microsatellite molecular markers.…”

Soybean is an economically important leguminous crop. Genetic improvements of soybeans have focused on enhancement of seed and oil yield, development of varieties suited to different cropping systems, and breeding resistant/tolerant varieties for various biotic and abiotic stresses. Plant breeders have used conventional breeding techniques for the improvement of these traits in soybean. The conventional breeding process can be greatly accelerated through the application of molecular and genomic approaches. Molecular markers have proved to be a new tool in soybean breeding by enhancing selection efficiency in a rapid and time-bound manner. An overview of molecular approaches for the genetic improvement of soybean seed quality parameters, considering recent applications of marker-assisted selection and 'omics' research, is provided in this article.

“…The phenotypic variations of hilum color may be associated with environmental effects due to changing temperature and humidity during seed developments. Molecular markers can help in the genetic determination of soybean seeds regarding hilum color since phenotypic traits may undergo environmental influence (Rabel et al, 2010).…”

Focusing on the genetic traits, seed coat and hilum pigmentation, in soybeans destined for human consumption is necessary due to the relevance of these traits for product acceptability by the consumer market. We investigated the traits seed coat, hilum color and bleeding hilum, in F 2:3 populations originating from crosses between the soybean grain type ('BRSMG 810C' with yellow seed coat, black hilum, and gray pubescence; bleeding hilum and white flower) with food types ('BRSMG 790A' with yellow seed coat and hilum, brown pubescence, no bleeding hilum and purple flower; 'BRSMG 800A' with brown seed coat and hilum, brown pubescence, no bleeding hilum and purple flower).We evaluated 317 plants from cross A ('BRSMG 810C' x 'BRSMG 790A') and 357 plants from cross B ('BRSMG 810C' x 'BRSMG 800A'). The resulting progenies adjusted to the expected ratio, considering four genes (R/I/W/T) controlling the expression of seed coat and hilum pigmentation for both crosses. In cross B, genotypes ii prevented the expression of the W and T alleles in the seed coat pigmentation. The expression of the ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 18 (4): gmr18372 L.C.A.A. Teixeira et al. 2 bleeding hilum phenotype varied and presented monogenic inheritance, with complete dominance for no bleeding hilum. The genes responsible for bleeding hilum are linked with the T_ genotype (brown pubescence). Thus, in these crosses,hybridization was an efficient means to obtain genetic variability. This will aid in the production of for food grade soybean cultivars.

“…In additional it is found that the locus R is also involved in the variegation phenotype affecting seed coat color. The r-m allele of this gene produces striped seed coat superimposed on an brown seed color, and the locus R and two additional independent loci I anthocyanin inhibitor and T tawny, control pigmentation and anthocyanin accumulation [2] [3].…”

Color is one of the phenotypic markers mostly used to study soybean (Glycine max L. Merr.) in the study of genetic, molecular and biochemical processes, due to their easy recognizability. The genetic control of several soybean natural variants has not been studied. The standard phenotype of R gene is black hilum on black seed. The genetic type T16 is the only occurrence with brown hilum on black seed coat and its genetic control was not described until now. The aim of this study is to understand the genetic control of seed coat and hilum color in the genetic types T16 and in the natural variants of Bragg, BR6 and BR13. T16 was combinined with Bragg P and BR13P (black seed color) and BR6M (brown seed color) and T236 (r-m). It was found that the genetic control of the brown hilum trait in black seed coat of the T16 genotype was controlled by two loci segregating independently and controlling the expression of the color of the hilum and the seed coat color. The expression of the brown hilum trait in black seed coat is dependent on locus T_, which controls pubescence color; therefore it occurs only in genotypes with tawny brown pubescence (T_), which caracterizes the pleiotropic effect of this locus on the trait hilum brown trait in black seed coat. The color of the hilum and the seed coat color belong to the same allelic sequence. No maternal effect was found in the expression of hilum brown trait in black seed coat.
