Fifteen rice hybrids contributed by six seed companies including four multinational and two national were evaluated for yield and yield attributing traits at NARC Islamabad, RRI Kala Shah Kaku and NIAB Faisalabad in comparison with cultivar KS-282. Two-hybrid viz., MK Hybrid 111 and 27P72 produced more productive tillers than KS 282. All most all the hybrids produced more number of grains per panicle and higher 1000-grain weight. Yield advantage of the hybrids over the commercially grown rice variety ranges between 4.59-21.33% except RH-257 and GNY-40. These two hybrids were low yielder by 4.20 % and 14.95%, respectively, than the check variety. PHB-71 was found better than KS-282 in cooking. Level of resistance to major insect pests and diseases was also discussed.
