摘要

To evaluate the growth performance and yield stability of seven selected local upland rice genotypes, field experiment was conducted in Buton Utara during rainy season 2015 and 2016. Seven selected upland rice genotypes were grown in six different locations and evaluated in a randomized complete block design with three replications. The variables observed were plant height, leaf area, number of tillers, number of productive tillers, panicle length, number of grains per panicle, number of filled grain per panicle, percentage of unfilled grain, 1000 grain weight, grain dry weight, and grain yield (t/ha). The results were analyzed using analysis of variance and combined analysis of variance for the interaction of environment x cultivars. Data on various growth characters and yield stability indicated different among genotypes and significant effect followed by the DMRT test at the significant level α = 0.05. The genotypes of Wakawondu, Wabalongka, and Mantebeka have high yield stability, while the genotypes of Waapolo, Warangka, Wabila Lambale, and Warara have low yield stability. Hence, Wakawondu, Wabalongka, and Mantebeka could be recommended for cultivation by the farmers in Buton Utara and these cultivars should be popularized in larger scale to make use of its superiority.
