The study entitled Agro-Morphological Characterization and Evaluation of Heirloom Rice in Lubuagan, Kalinga from January to August 2019 at Lubo, Lubugan, Kalinga. It was undertaken to determine the characteristics of the two Heirloom Cultivars in Tanudan condition. Randomized Complete Block Design was used in a 450 square meter. The study used the International Rice Research Institute (IRRI) Descriptors for wild and cultivated Rice as Guide in the collection of heirloom rice agro-morphological characteristics of the traditional landraces.
Variations of Distinct characteristics on the morphological traits of Intan and Guinannay varied on the following: anthocyanin coloration and intensity of green color of the leaf blades, collar color; ligule color, culm habit, culm underlying node color; lemma apiculus color; awn distribution, awn color; panicle branches attitude, panicle testability, lemma and palea color, and caryopsis color. Quantitative traits of the two varieties were recorded. Intan has greater plant height at maturity, number of culm per plant, culm length, greater number of tillers per plant, longer panicle length, longer leaf blade, and wider flag leaf. Though, Guinannay have longer grains, greater number of panicles, longer size of ligule, wider leaf blade, wider diameter of culm, longer awn, and wider width grains. Thus, plants that have greater number of tillers, longer panicle, longer and greater culm number, wider flag leaf produce greater yields and longer grains have greater grain weight.
