Yield is a complex entity. The pre-requisite for achieving high yields in rice depends on identification of superior new genotypes for various traits associated with yield. These characters may help in advancing the yield like the plant height, tillers per plant, length of panicle, grains per panicle, grain weight and their relationship with yield and direct and indirect contribution to grain yield. The present study was conducted to identify the yield and its related characters of all the rice cultivars which are collected from the hill farmers of Manipur. Field experiment of 90 local rice cultivars were conducted in the experimental farm of ICAR, Lamphel, Imphal, Manipur. Sample random sampling technique with a sample size of 6 competitive plant were study in the present study. Data of plant height, total tillers per plant, length of panicle, total spikelet's per panicle, grain per panicle, grain weight, grain yield per plant were analysed. The present finding shows that a large number of local cultivars are used by the hill farmers of Manipur without appropriate selection. Some of these cultivars were having those agronomic traits which are considered to be associated with yield characters of rice. If improved high yielding varieties for upland rice cropping is not available to the farmers' they can select to those local cultivars having desirable yield characters.
