  Background: Understanding the distribution of fatty acids in wild soybean accession collected in Japan and the relationship of geographic and environmental factors in the accumulation of fatty acids is fundamental for using the wild accessions as resources for the future development and selection of new soybean varieties with desired traits. Materials and Methods: The fatty acid composition of seeds from 319 wild soybean (Glycine soja) accessions collected in Japan were evaluated using gas chromatography. Results: The distributions of palmitate (16:0), stearate (18:0), oleate (18:1), linoleate (18:2) and α-linolenate (18:3) in seeds were determined for each accession. Significant inverse correlations were observed between the oleate and α-linolenate contents and the linoleate and α-linolenate contents. Moreover, a weak inverse correlation between the stearate and α-linolenate contents was indicated and an inverse correlation between the palmitate and linoleate contents was also found. The total palmitate content and total stearate content of Glycine soja collected from regions with high annual temperatures were high and the total α-linolenate content of Glycine soja collected from regions with a low annual temperature was high. Conclusion: These results provide diverse and wide-ranged fatty acid information of Japanese wild soybean resources according to climatic region for improving of new soybean varieties in global environmental changes.

  Background and Objective: Turfgrass resistance to heavy traffic and wear damage is one important quality in turfgrass. Since it differs within species, some wear resistance tests have been developed to further differentiate turfgrasses but they are more laborious and require longer time. Therefore, the aim of the study was to build an efficient tread loading system and evaluate its load condition on 3 commercial turfgrass cultivars: Zoysia matrella ‘Emerald’, Zoysia japonica ‘Meyer’, Cynodon dactylon×Cynodon transvaalensis ‘Tifway’ and a new Zoysia matrella cultivar ‘Wakaba’. Materials and Methods: A multiple tread loading system was constructed to accommodate 32 grass trays. Treading test was conducted on 4 turfgrass cultivars and the number of erect stems, stolon dry weight and green turf coverage were analyzed. Results: The newly registered cultivar ‘Wakaba’ had the highest number of erect stems and green coverage in both treading and non-treading (control) tests as compared to zoysiagrasses ‘Emerald’ and ‘Meyer’, while bermudagrass ‘Tifway’ least performed in all tests. Conclusion: It is concluded that tread loading system is efficient to analyze treading damage for multiple turfgrasses in a short period of time. In addition, the new cultivar Zoysia matrella ‘Wakaba’ has high resistance to treading and utilization of this cultivar is recommended.
