The investigation was carried out under aerobic condition using the line x testers mating design and studied for yield and its components traits. The objective of this study was carried out to identify the best heterotic rice hybrids suitable for aerobic condition in water short areas. Thirty three hybrids along with three lines, eleven testers and one check Indira aerobic 1 were raised in Randomized block design with three replications under aerobic condition. Two hybrids showed desirable performance for all the yield traits. However, most of the hybrids involving aerobic and male parent exhibited hybrid vigor for yield and its component traits. Parental lines of the hybrids also had high per se performance for grain yield. Out of thirty three, two hybrids viz., IR 58025A/ Indira Barani Dhan 1 and IR 58025A/Dukong exhibit heterotic vigour for yield and maximum number of yield components and showed better adaptability to aerobic conditions. Finally these hybrids can be commercially exploited under aerobic condition.
