Abstract: In order to explore new varieties of Coix suitable for cultivation in Yunnan Province, thus improving the level of productivity of Coix planted in Yunnan. By comparising the tested lines of 10 Coix lines that were planted in areas of Wenshan, Yunnan, agronomic traits (growth period, plant height, stem diameter, number of tillers per plant, total fruit number, kernel weight, etc.) was analyzed and compare its yileds. The results showed that: (1) effective tiller number, total fruit number per plant, and seed weight was positively correlated with yield, especially the yield was significantly correlated kernel weight; (2) lines of YLO and Y7-1 had shorter growing period, plants shorter, thin stems, compact plant type, lodging resistance, etc. features, both of them were ideal plant type; (3) Y9-7, Y3-4, and Y12-2 black were the late-maturing varieties, they had good features in kernel weight, grain appearance, and yield; (4) YGL and Wen Yi II were late-maturing varieties, both of them showed the growing period between 150 to 155 days, plant height, tillering ability, stem diameter, and high biomass production, however, lower economic output; (5) the tested varieties (lines) of Y9-7, Y3-4, Y12-2 (black) had obvious advantages, and was in line with selection of high quality, high-yielding new varieties (lines) from comprehensive characters, yield, adaptation and other indicators.
