  In this study, we describe the insertion/deletion (indel) polymorphism of the THRSP gene evaluated using 1% agarose gel and 8% polyacrylamide gel electrophoresis in a sample of (17 breeds of chicken including 3 foreign breeds and 14 chinese native breeds). For the THRSPα gene indel polymorphism result, allele frequencies varied, between chinese native chicken and a foreign chicken. A high frequency of allele B (0.91) and a low frequency of allele A (0.09) were observed in Leghorn chicken, which has been selected for laying performance. Based on variation in allele frequencies among populations, either the low frequency of allele A or the high frequency of allele B could be linked to fatness trait of the chicken. In conclusion, THRSPα gene might be used as a molecular marker in high quality broiler assistant selection breeding program.

  Soybean [Glycine max (L.) Merr.] seeds contain a high concentration of the isoflavones daidzein and genistein, which are considered to be compounds beneficial to human health. Our objective was to determine the influence of breeding and selection for yield on the isoflavone concentration of short-season cultivars. A collection of 14 historical cultivars released from 1934 to 1992 was grown at Ottawa for 12 yr under identical cultural conditions. Seed samples, taken at harvest, were examined using near-infrared reflectance in conjunction with traditional chemical methods to measure the concentration of daidzein, genistein, and total isoflavones (TIF). A linear regression equation developed based on the changes across time of cultivar release was used to determine the improvement rates for various soybean parameters. Across the 58 yr of breeding history, yield and oil concentration increased by 0.43 and 0.24% per year, respectively, while protein concentration decreased by 0.15% per year. Across the same time period daidzein, genistein, and TIF increased by 1.04, 1.47, and 0.98% per year, respectively. Moderate broad sense heritabilities of 43, 45, and 44% were calculated for the aforementioned isoflavones. Genotype main effects + genotype x environment interaction biplots revealed that recent cultivars with high isoflavone concentration were more prone to environmental influence than older cultivars. In the short-season region, plant breeders should be aware that selecting for higher yield may indirectly select for higher isoflavone concentration.
