It was registered and released in 2014. The average yield was 2 858.5 kg/hm^2 in Henan province regional test of high quality, 12.43% higher than the check variety Fengyou 9 in 2010-2011 and 2011-2012. Its yield was 3 478.8 kg/ha in Henan Province productive test of high quality,9.52% higher than the check variety Fengyou 9 in 2012-2013. According to the test results in 2011-2012 and 2012-2013, the seeds quality of Shuangyou 092 was very good with near zero erucic acid （0.0%, 0.1%） in fat acid, 17.19 μmol/g and 19.78 μmol/g glucosinolates in its meal, the oil content of 46.60% and 45.76%. The cultivar was resistant （tolerant） to Sclerotinia, virus diseases, cold, and lodging. Its high yield and high quality can be obtained by planting in large scale, sowing at right time, rational close planting, balancing fertilizer and harvesting at right time.展开更多

High-oil maize has been selectively bred for many years due to its high oil content and nutritional quality. However, compared with normal maize, the progress of high-oil maize breeding is hindered nowadays. Main problems are scarce of high-oil maize germplasm, conventional breeding methods, and slow genetic research progress on oil content and fatty acid composition. In this study, germplasm innovation and gene mining of high-oil maize were reviewed to provide theoretical reference for genetic breeding and utilization. Several high-oil basic populations have been developed after more than 100 years of selection, which have served as the unique resources for high-oil maize breeding. They have also been used to dissect genetic architecture of oil biosynthesis in maize kernel. Using linkage and association analyses, many QTLs and loci associated with oil content and fatty acid composition have been identified and mapped. In addition, some candidate genes for QTLs have been validated to regulate maize grain oil content and fatty acid composition. Prospect for high-oil maize was also discussed to provide knowledge about genetic mechanism of oil biosynthesis and improvement of kernel quality in maize.展开更多

In the same time we are doing 10 generation of soybean breeding near Sanya on Hainan Island during the October to May. We made cross 398 combinations and a lot of propagation of soybean elite. We select a best local popularized variey for cross with soybean variety with 1-2 best character for breeding, for example high yielding, high oil or high protein content, high resistance to nematode and others We made alternate breeding in North and on South. In the same time we test breeding materials in two conditions: soil with high fertility and low fertility. Finally, we released two soybean cultivars: Zhonghuang 12 and Zhonghuang 13,and two cultivars will released this year. We test more than 10 soybean lines in 15 provinces. We got a good line with high oil content and high protein content. And we developed several soybean lines resistant to soybean cyst nematode.展开更多
