Varietal Trial of Traditional Upland Rice (Oryza sativa L.) Varieties Collected in the Province of Negros Occidental
Thirteen traditional upland rice varieties (Kadidit Pilit, Red 64, Masipag 9, Masipag 15, Dinorado, Mindoro, Camuros, Masipag 22, Palawan, Suleg, Biday, Pilit , Pilit Talacdan) were evaluated in Randomized Complete Block Design (RCBD) in three replicates at the experimental area of Central Philippines State University (CPSU), Kabankalan City, Negros Occidental from November 2012 - April 2013. The parameters compared were their agronomic data on growth and yield, including grain characteristics. These data were processed using the one-way Analysis of Variance (ANOVA) with the Statistical Tool for Agricultural Research (STAR) (Version 2.0.1) while Duncan’s Multiple Range Test (DMRT) were used to compare significant treatment means at 1% level. The upland rice varieties showed significant variation in growth, yield showed distinct grain characteristics. Biday variety was the tallest, produced longer and wider leaves, and bore the longest panicle. Mindoro and Masipag 22 produced the most number of tillers. Pilit talacdan had the biggest culm, produced the heaviest panicle, with the highest number of filled grains per panicle. Pilit variety gave the heaviest weight of 1,000 grains. The grain features were also found to be distinct in each variety. The yield significantly varied among the upland rice varieties. Pilit and Pilit Talacdan gave the highest yield among the varieties grown at CPSU condition. The performing varieties would be used for upland rice improvement and breeding program and for further verification in the farmer’s field.
