High Density Linkage Map

Abstract Seed coat cracking (SCC), particularly the Type-I irregular cracking, is critical in determining the quality of appearance and commercial value of soybean seeds. The objective of this study was to identify the quantitative trait loci (QTLs) for SCC with high-density genetic map. One hundred sixty-seven recombinant inbred lines (RILs) developed from a cross between Uram (SCC-resistant) and Chamol (SCC-susceptible) were evaluated for SCC over 2 years (2016–2017). The QTL analysis identified 12 QTLs located on chromosomes 2 (D1b), 6 (C2), 8 (A2), 9 (K), 10 (O), 12 (H), 19 (L), and 20 (I). Out of the 12 QTLs, qSC2-1, qSC9, SC10-1, qSC10-2, and qSC12 were novel QTLs and the other seven QTLs (qSC2-2, qSC2-3, qSC6, qSC8, qSC19-1, qSC19-2, and qSC20) were found to co-localize with the previously identified QTLs. The mean SCC of the RILs of early maturity group was significantly higher than that of the late maturity group, suggesting an association between SCC and maturity loci. In addition, although 10 QTLs were distantly located from the maturity loci (E1, E3, E4, E7, and E10), qSC10-1 and qSC10-2 co-localized with the maturity loci E2. The results obtained in this study provide useful genetic information on SCC which could be used in the SCC breeding programs.

Heavy Grazing

With the decline in pasture quality in southern Australia, the development of management strategies to improve nutrient supply for grazing animals is essential and requires a clear understanding of the interaction between animals and plants. The impact of grazing intensity on the morphology of subterranean clover was previously examined. This paper reports the effect of grazing intensity on the nutritive value of subterranean clover, and the variation in quality of cultivars during the growing season. Grazing intensity influenced nutritive value and interacted with cultivar maturity. Heavy grazing depressed dry matter digestibility (DMD) by 5 percentage units in October for early maturity cultivars but increased DMD by 3 percentage units in September for mid maturity cultivars. The influence of grazing intensity on nitrogen content was small. Heavy grazing did not affect acid detergent fibre for the early maturity group, but depressed it for the mid maturity group throughout the season. Acid detergent lignin remained comparable for all cultivars during the season. Mineral content of subterranean clover showed variable response to grazing treatments. Nutritive value varied among cultivars within each maturity group. DMD ranged over 53–64%, 44–62%, and 45–53% for early, mid, and late maturity groups, respectively, at the end of the growing season. The cultivar rank in all nutritional parameters changed with the progress of the season. The large ranges in the decline rate of DMD within each maturity group during the last 8 weeks of growth gave an indication of the potential quality of the cultivars during late spring and early summer. Despite the variation in mineral content there were no cultivars in which the concentration of minerals was below the minimum requirements of sheep. These results indicate that there is a potential for the selection of high quality cultivars within a breeding program, and that indicative targets of grazing intensity need to be further developed with a focus on pasture quality.

ABSTRACT: The objective of this study was to evaluate the effect of timbó seed coat on the physiological and sanitary quality of soybean seeds. Timbó seeds were collected from mature fruits in the Cerrado. The external layer of the seed coat was removed and crushed in a mill and used in the treatment of soybean seeds. Three lots of soybean seeds were used, from high, medium and low vigor seeds. The treatments were: powder; gel; hydroalcoholic extract; synthetic fungicide (Vitavax® - Thiram 200 sc), and untreated seeds. The physiological quality of the soybean seeds was determined by standard germination, accelerated aging, length, fresh and dry mass of seedlings. Blotter test was used to determine the sanitary quality. The statistical analyze used was a completely randomized 3 × 5 factorial design, considering three seed lots and five treatments. Treatment with the coat seed extract and gel improves the physiological quality of soybean seeds from low vigor lots. The treatment of seeds with gel decreases the incidence of Fusarium and Penicillium genus; and treatment with the powder reduced the incidence of the Cercospora genus.
