Yield traits between 15 purple-pericarp rice lines (Oryza sativa L.) were evaluated. The examination was conducted between 24 October and 13 March 2016 in Chonburi province, Thailand. Treatments were 13 rice lines including BP2012-005, BP2012-010, BP2012-009, BP2012-258, BP2012-279, BP2012-350, BP2012-375, BP2012-412, BP2012-430, BP2012-445,BP2012-489,BP2014-001, BP2014-002, and compared to 2 commercial rice varieties, i.e. Riceberry and Khao Luempua. Transplanting method was used with 1 seedling per hill and 30 x 30 cm spacing. Results revealed that unhusked grains at 15 % moisture showed highly significant difference between treatments. BP2012-009 and BP2014-002 singnificantly produced maximum yield/Rai of 470.40 kg and 464.03 kg, respectively, and followed by BP2014-001, Riceberry, BP2012-010, BP2012-005 and BP2012-279 which the yield/Rai of 452, 448, 440, 438 and 432 kg, respectively. Whereas BP2012-412, BP2012-430, BP2012-445, and BP2012-489 yielded lower than Riceberry but higher than Khao Luempua as compared to the rice variety with the lowest yield/Rai of 134.40 kg. The current experiment indicated greater yield of 2 rice lines, BP2012-009 and BP2014-002, than Riceberry. BP2012-009 had only 110 days of harvesting date compared with 139 days of BP2014-002. Results also indicated that 4 rice lines including BP2014-001, BP2012-005, BP2012-010, and BP2012-279 showed non singnificantly differerce in yield compared to Riceberry, It suggested that these rice lines are promising for further selection and improvement as novel lines in the future.
