Issue Date

Abstract

The participatory varietal selection (PVS) is conducted across the country with the 16 RFOs in both DS and WS to test newly-released varieties, fine-tune new technologies, and determine the variety suited for a specific region. Simultaneously, PVS-RM (research managed) trial sites conduct field days with varietal selection (preference analysis) and sensory evaluation of PVS entries. Yield stability, pest and disease resistance, and grain quality were the main criteria used for varietal competitiveness. Through the PVS, NextGen recommended varieties according to the results of the National Cooperative Tests for rice (NCT), farmers' preference (from regional coordinators' reports), value chain analysis project, and the rice seed system workshop output. The most adapted irrigated inbred varieties across regions are: PSB Rc10, Rc18, Rc82, NSIC Rc158, Rc218, Rc224, Rc226, Rc298, Rc302, Rc308, Rc352, Rc354, Rc356, Rc358, Rc360, Rc394, Rc400 and Rc402 with an average yield range of 5.0-6.2 tha-1 for transplanted and 5.1-5.5 t/ha for transplanted and 8.0-14.0 t/ha when direct seeded. Registered seeds of the 3-5 most preferred and adapted varieties in the PVS are provided to accredited seeds produced are supervised by the Bureau of Plant Industry's National Seed Quality Control Services (NSQCS), and are available for the farmers.
