Abstract. Sudika IW, Soemeinaboedhy IN, Sutresna IW. 2023. Genetic diversity and gain quantitative characters of maize from index-based selection at two dry lands in Lombok, Indonesia. Biodiversitas 24: 11-19. land is poorly reported. This research aims to study the genetic several traits Amor-Amor Pererenan, A randomized block design with three replications was applied experiment. The materials used nine populations, namely eight populations one initial population. data were analyzed for variance 5% significance level. results showed that yields categorized as moderate, weight cobs harvested per plant narrow both locations. fresh stover Pererenan wider than Amor-Amor, but still same category, which medium. These had a significant moderate category locations, except plant, high Pererenan. seed positive phenotypic correlation yield. Yield can be increased through by using
