Evaluation on characteristics of black pericarp rice germplasm among traditional varieties in Guizhou

Based on the agronomic characters of rice germplasm among traditional varieties from Guizhou, the characerization of 81 accessions in black pericarp rice was conducted. The results showed that these varieties were widely and mainly distrbuted in the minority areas including Qiannan and Qiandongnan, accunting for about 82.8 %. They were rich in genetic diversity, and the variance of quantitative characters was complicated, some of elite germplasm with usefull characters will be helpful to improvement for spacial rice breeding.
