Abstract
Identification of tobacco varieties with better yield performance and stability is an important aspect in variety recommendations to increase farmers income. This research aims to determine the yield performance and stability of several new lines of tobacco in various environments. Nine new lines of tobacco plus two check varieties have been evaluated in 3 locations: Ngimbang Sub-District Lamongan Regency, Kabuh Sub District Jombang Regency, and Plandaan Sub District Jombang Regency, East Java Province. The research was carried out in the years 2019, 2020, and 2021. Of the 9 new lines of tobacco tested, there were four lines capable of producing consistently high dry chopped tobacco in all locations and years, namely BEI 304 S, BEI 305, BEI 305 S, and BEI 304, with average dry chopped yields of 1,764 tons, 1,687 tons, 1,674 tons, and 1,620 tons per ha, respectively. These four lines also have a better quality index and crop index than the check varieties. All lines tested had dry chopped yield, quality index and plant index that were stable between locations, but the BEI 314 and BEI 314 S lines were not stable across years.
