Philippine Rice Research Institute (PhilRice), is one of the institutions that helps to develop high-yielding rice varieties and every year it releases new variety that would help farmers to produce enough rice for consumption. PhilRice Negros conducted a varietal demonstration trial to determine which among the newly-released varieties will be adapted by farmers in Negros. PhilRice Negros belongs to the soil series Guimbalaon which needs organic matter incorporation to be suitable for rice production. Pests and diseases such as yellow stemborer, rice black bug, rice bug, tungro, rice blast and bacterial leaf blight are some of the limiting factors that could negatively affect the yield performance of the varieties. The yield performance and pest reactions of newly released varieties were evaluated and best performing varieties were selected for recommendations. In addition, Farmers' preference was also measured based on the crop stand in the field during Station's Lakbay Palay. Among the 12 varieties evaluated, NSIC Rc354 obtained the highest yield for 2019DS followed by NSIC Rc360 and NSIC Rc442 with a mean yield of 6.42,5.88 and 5.78 t/ha, respectively. In addition, NSIC Rc360, 354 and 400 were the preferred rice varieties by the farmers based on the phenotypic characteristics of the variety. Thus, topped varieties will be recommended to Business and Development Unit in the station for seed production so that it will be available to the farmers.
