Variety Development

Citrus Scion breeding produces new potential varieties by hybridization or induction of mutations and then evaluates them at several locations in California.

Preliminary evaluations of new citrus varieties for commercial potential and adaptability to California growing conditions benefits the California citrus industry by providing primary data to assist growers in choosing appropriate varieties for the domestic and export markets.

Our progress on the two portions of this study is outlined from the following two: Navel Strain Trial and Delta, Midknight and Olinda Valencia Orange Trial.

By acreage, lemons are the second-most important citrus crop grown in California after navel oranges. Lemons are grown in the coastal regions, in the San Joaquin Valley, and in the desert. Each of these regions has a distinct climate that affects tree growth, fruit maturation time and fruit quality.
