The seeds had a high kernel percentage (53.67%± 7.51), oil content (52.21%± 4.01), and biodiesel yield (99.77%± 0.21). Among the fatty acids in the oil were high percentages of linoleic acid (41.66 ± 2.26)% and oleic acid (28.44%± 2.03). Most of the fuel properties complied well with the ASTM D6751-10, EN 14214-08, and GB/T 20828-2014 standards. The 13 sampling areas were grouped into four clusters based on different kernel percentage, oil content, biodiesel yield, and fatty acid composition. The results showed that the quality of kernel oils from seeds from Ar Horqin Banner was the best, although kernel oils from seeds in all 13 areas were suitable for biodiesel production. This study provides a basis for selecting optimal sites to harvest seeds from X. sorbifolia.展开更多

The research on the genetic diversity of rice landraces resources can provide some reference for the protection and utilization of high-quality germplasm resources and breeding of new varieties. In this study, we reviewed the concepts of genetic diversity, research methods, genetic diversity of quality traits of rice landraces in Taihu Lake region and summarized the relevant utilization value of the rice landraces from Taihu Lake region.展开更多

We reviewed the research progress in disease resistance, insect resistance, stress, quality improvement and genetic resources＇ utilization, respectively. The enormous application of transgenic tomato was also summarized in increasing resistance and improving quality. It was expected to provide references for the research and im- provement of transgenic tomato.展开更多
