Hello all,
A friend of mine recently sent seeds from his visit to the Florida Citrus Arboretum. Two that I have not found any info on are: sun chu sha and sundiatgo. Does anyone know about these two?
thanks,
Matt

Sun Chu Sha is normally used only as a root stock. Here is the information given by the University of Florida.

Sun Chu Sha mandarin (SCS). This rootstock was released because it was thought to have good tolerance to calcareous soils and blight. It has had a modest impact in our industry and is widely considered as just another Cleo. That opinion is probably justified using data from both commercial plantings and research trials. However, there have been some surprises and some distinctive traits have been observed.

In a trial of Fallglo, Sunburst, and several unreleased mandarin types on eight rootstocks at the Water Conserv II site near Winter Garden. The trees on SCS were comparable to those on Cleo, but often slightly less vigorous and better yielding. Sun Chu Sha is a suitable rootstock choice for calcareous and clay soils, for places unsuited to Swingle, and for Hamlin and Murcott. Cleo and other mandarin rootstocks are questionable choices for nucellar Valencia budlines; however, in Valencia sweet orange and Marsh grapefruit Indian River trials, trees on SCS were among the top performers. In a Gulf Coast Valencia planting with whole beds of trees planted in 1991 on Malabar and Holopaw soils, 30% of the trees on Cleo have gone out to blight with virtually no trees lost on SCS. Yield has been about 4 to 6 boxes/tree in recent years on SCS and 3 boxes for the trees on Swingle. The SCS yields were exceeded only by those of the trees on rough lemon. - Millet

thanks Millet

Matt,
I found this on the UCR Citrus Variety site about the Sun-Chu-Sha-Kat.

The Sun-Chu-Sha-Kat has a long history from 1178 AD. After reading about it I ordered some seeds. It should be an interesting red Kat.

Thanks Terry. Philippines did play a good part in the citrus industry. I didn't know that we used to have a good collection of citruses in Lipa, Batangas before World War II.

The College of Agriculture at Los Baños used to be the extension of the University of the Philippines at Diliman, Quezon City, Philippines. The College of Agriculture has long been converted into the University of the Philippines at Los Baños (UPLB).

It parallels the history of how the College of Agriculture in Davis is an extension of the University of California at Berkeley. The College of Agriculture is now the University of California, Davis.

And in more ways than one, the atmosphere of the community has many things in common. International melting pot of various nationalities, strong interests in Agriculture, surrounded by biotech companies and various research institutions close together. Many residents are college and graduate students, some are professors and scientists, the academic, scientific and industrial life comingling, socializing and cohabiting together, and except for the California wines, have similar night life too.

So I didn't really dramatically miss UPLB as it has some resemblances and parallels in Davis.
