蒼梧是在廣西北部吧？南越國派出桂林監耶。
楚國原地在湖北耶，後來才擴張至湖南耶。

廣西的不清楚，廣東的乃至少經楚國傳入的耶，而在此前也有周人傳入的傳說耶，羊城乃因此而得名耶。

        Abstract: Two natural common wild rice populations without cultivatedrice introgression from Dongxiang, Jiangxi Province, and Guilin, GuangxiProvince, and a natural population of common wild rice near cultivated rice fromFusui, Guangxi, were studied using chloroplast DNA PCR technique. Results showmost Dongxiang population plants in the ORF100 gene of Pst-l2 fragment are indicaand most plants of Guilin and Fusui populations are japonica.

Abstract:

By using 19 pairs of primers that could identify two subspecies (indica and japonica) of cultivated rice (Oryza sativa L.), the indica-japonica differentiation of 56 individuals from the natural population of common wild rice (Oryza rufipogon Griff.) in Yuanjiang was analyzed by SSR (microsatellite DNAs, or simple sequence repeat). Of the 19 pairs of primers, 17 pairs (89.47%) could amplify only one kind of band type among all of the individuals, but primers RM251 and RM18 could amplify polymorphic band types. The bands amplified by 16 pairs of primers (84.21%) were identical to the indica-japonica diagnostic bands of relevant locus in cultivated rice, including 11 japonica-like loci and 4 indica-like loci. The bands amplified by the other three pairs of primers (RM18, RM202, RM205) were different from indica or japonica diagnostic bands of  cultivated rice. The results showed that according to 19 loci analyzed, 84.21% of SSR loci in genomic DNA of common wild rice in Yuanjiang displayed indica-japonica differentiation and 13.79% of the loci still kept primitive, and most of the detected loci were homogenetic in the natural population.
