    Abstract:

    In order to further improve evaluation and its effective utilization of rice landrace in Guangdong Province, we used 2974 accessions catalogued in the national genebank that 9 rice quality traits as basic data to study. The geographic distribution of rice quality traits were analyzed, and rice quality trait diversity among each area were compared, and the correlation between some ecological factors and rice quality traits were studied. The rice landrace in Guangdong province showed higher brown rice rate and milled rice rate, richer diversity of protein content, larger variation in gel consistency, and not many materials reached the national standard in amylose content. High-quality rice germplasm mainly distribute in Southcentral rice area of Guangdong province. The result also showed that amylose content, gelatinization temperature and gel consistency were the main impact index of rice quality formation. Humidity and temperature difference among areas were the main impact factors of rice quality formation. So, it is very important for high quality rice breeding and genetic background expanding to use rice landrace in Guangdong Province effectively.
