International Association of Hydrogeologists and China

Before 1985, there were a few Chinese participators for International Association of Hydrogeologists which founded in 1956. The Chinese team composed of senior hydrogeologists attended the 17 th and 18 th IAH congress in 1985. More and more Chinese delegates were present at the conferences since then. The IAH National Chapter of China was first established in 1987 and organized related activities continuously since that time. The IAH members in P.R. China increased in these years. IAH congresses have been hold in China twice. The 21 th congress was held in Guilin City in October, 1988. The 34 th congress was held in Beijing in October, 2006. The IAH China Chapter serves for all IAH members and other scientists promoting groundwater sciences in China. There were a lot of national conferences on Hydrogeology and Groundwater sciences held almost every year since 1987. Those national conferences associate with Commission on Hydrogeology, Geology Society of China in operation. Many Chinese IAH members were the editors and responsible for the Chinese translation for the abstract of Hydrogeology Journal. The Journal of Groundwater Science and Engineering is an international journal for the natural sciences. The sponsors are IAH China chapter, Institute of Hydrogeology and Environmental Geology, CAGS.

Genome-Wide Association Studies Reveal New Genetic Targets for Five Panicle Traits of International Rice Varieties

Narrow genetic background is a key limiting factor in breeding stable high-yielding rice. The introduction and utilization of international rice core germplasm is an important way to increase the genetic diversity of domestic rice varieties. We conducted a genome-wide association study on 5 panicle traits of 315 rice accessions introduced from the international rice micro-core germplasm bank. Based on the tests from Yangzhou of China and Arkansas of American, environment exhibited a significant impacts on panicle length and primary branch number, while grain length, grain width and grain length/width ratio were insensitive to environment changes. We discovered a total of 7, 5, 10, 8 and 6 chromosomal regions or single nucleotide polymorphism marker loci that were significantly associated with primary branch number, panicle length, grain length, grain width and grain length/width ratio, respectively. Among them, eleven regions were associated with grain shape and one region associated with primary branch number, showing the good consistence in two different environments. Significant linear correlation was discovered between the average trait value and the number of favorable alleles carried by the varieties in all associated loci. Among the associated loci, varieties in aromatic and tropical japonica sub-groups possessed most favorable alleles, while those in temperate japonica sub-group contained the least. The domestic varieties mainly harbored unfavorable alleles in six of the associated loci being detected. On the contrary, 15 varieties from 11 different countries harbored more favorable alleles （as many as 30 or more） than the others. Remarkably, all these 15 varieties belonged to the tropical japonica sub-group. In conclusion, our study demonstrates that varieties in the tropical japonica sub-group had high potentials for breeding stable high-yielding rice. Based on this discovery, we proposed a new approach for improving the panicle traits of domestic rice by using tropical japonica varieties.

The Chinese Association For International Understanding(CAFIU) and the cooperation with The Australian Rotary

Friendship Exchange The origin of our long cooperation dates back to 1987 when CAFIU invited the Liberal Party of Australia to visit China. The then past Tasmanian State President of the Liberal Party Mr. Ian Chalk was one of the first to join the delegation to visit China.
