Effect of the Nitrate Reductase Genes (Nia) on the Quality of Different Lettuce Genotypes for Low Nitrate Content
Genotypic variation in nitrate concentrations of different lettuce genotypes belonging to four types (Butterhead, Cos/Romaine, Crisphead, and Stem lettuce) and its relationship to nitrate reductase genes (Nia) for low nitrate concentrations of leaves was investigated. The results showed that the Romaine genotype ' Lobj …
