Abstract: In India, 65% of the population depends on rice as their staple food and the country is a huge contributor to the global rice production. However, biotic and abiotic stresses are causing huge yield losses. Many developed new improved cultivated rice for resistance against Blast and BB through molecular breeding approach involving DNA marker, but the improved cultivars yield was not up to the mark. In order to improve rice production and productivity there is an urgent need to improve popular rice varieties by having resistance genes against biotic stresses along with yield related traits. Agro-morphological evaluation was carried out in 29 advanced backcross lines. Replication wise data was recorded for eight yield and yield contributing characters viz., days of 50% flowering (DFF), plant height (cm), number of productive tillers per plant, panicle length (cm), number of filled grains per panicle, grain yield per plant (g), 1000 seed weight (g) and grain type and RBD analysis was carried out. In case of Tellahamsa derived lines, six progenies shown significant superiority over Tellahamsa and four lines were on par with Tellahamsa for yield. Among 10 MTU1010 derived lines, five lines showed significant superiority over MTU1010 for yield.
