Citrus sinensis (L.) Osbeck RUTACEAE
Received as budwood from USDCS, Indio, CA, via CCPP, 1962.

Description from The Citrus Industry Vol. 1 (1967)
"Fruit medium-large, round to slightly oblate; moderately seedy (depending on pollination). Well-colored under favorable conditions. Rind medium-thick, and surface smooth and finely pitted. Flesh well-colored; juicy, lacking in acid; flavor sweet. Holds well on tree with little loss in quality. Earliest in legal maturity because of low acidity, but for better juice content and quality should be left on tree somewhat later.
Tree moderately vigorous, precocious, and prolific. Marked tendency to bear fruit in clusters. Smaller than most other varieties, presumably because of early and heavy bearing.
Although propagated to a limited extent earlier, trees were not available for commercial planting until 1940. Because of its early and heavy bearing and good fruit size, Marrs is currently a popular early maturing variety in Texas. Its principal fault for processing is the low acidity of the juice."
