Abstract

Red rice is an essential food and has nutritional content, but farmers production and interest in red rice cultivation are still relatively low. One effort to develop and increase brown rice production is planting superior varieties with selection efficiency. The purpose of this study was to determine the correlation between yield components and yields of the six promising lines of red rice in paddy fields and to know the yield components that were positively correlated very significantly to the results in paddy fields. The research design used was a randomized block design (RBD) consisting of 6 crosses, namely GS11-1, GS11-2, GS12-1, GS12-2, GS44-1, GS44-2, and one comparison variety, Trisakti. The results of the analysis showed that there were two components of yield that were highly positively correlated with yields of red rice, which were positively correlated significantly, including the number of productive tillers with grain yield per clump (0.83 **) and the weight of 1000 grains with grain yield (0.57 **).
