The origin of C35 was a seedling of Ruby orange x Webber-Fawcet trifoliate, made in 1951. UCR released it in 1986. Trees on C35 have relatively good freeze tolerance where the climate induces dormancy. As Kumin wrote, in climates with warmer winter temperatures, such as Florida and Texas, trees may be much less freeze tolerant. However, they are typically somewhat more susceptibleto freezes than those on Trifoliate. Fruit also has relatively good freeze tolerance. C35 has good compatibility with all oranges, grapefruit, and Lisbon lemons, but strong incompatible with Eureka lemon. Nearly all mandarins perform well for at least 10 to 15 years, but many eventually develop bud union crease and decline. Lastly, C35 is well adapted to loam, sandy loam and sandy soil, May perform poorly on very heavy soils with poor drainage Poor tolerance to soils having high chlorides and also calcareous soils, where it is somewhat worse than Carrizo
