And the tree itself produces produces about 15 seeds per fruit, which is important if you're in the business of selling or planting planting seeds for rootstocks. SEEDS 5 TO 10 CENTS Because of these qualities, Troyer Troyer citrange seeds last season cost 5 to 10 cents apiece. Each fruit was worth approximately 50 cents. And for a field box of fruit you paid $300. The demand even though several dozen growers and nurserymen now supply Troyer is phenomenal. .

It is one of two original parents of the Troyer citrange, a variety developed especially for the cooler areas of North America. Dr. W. P. Bitters, associate horticulturist, at the station (above) picks one of the fruit to be shown visitors at the station's open house Feb. 14. jwhy Troyers have, only recently spread through California, Dr. Bit ters explains that until the ad. vent of quick decline (about 1940) growers did not need a rootstock with Troyer's resistant qualities, since the sour orange served that need. It took 10 years of testing, testing, after quick decline betrayed the weakness of sour orange, to prove that this Troyer variety, a cross between the Washington na vel and the trifoliate orange, had valuable characteristics as a rootstock. . The late Dr. Walter T. Swin gle, a U.S. Department of Agri culture horticulturist, made the cross in 1909 from which came Riverside's first Troyer cit ranges. The tree was named in honor of A. M. Troyer, horticul turist on whose place in Fairhope, Alabama, the hybrid was first fruited. BEGAN IS 1EW0 Dr. Leon D. Batchelor, a sta tion horticulturist as well as its director (1929-1951), (1929-1951), (1929-1951), began work ing with the sour, unlikely-look unlikely-look unlikely-look ing little fruit of this cross in 1940, seeking a substitute root- root- stock for sour orange, one that could withstand the ravages of quick decline and resist gumos- gumos- is. Quick decline had eliminated further . possibilities of using sour iorange seedlings for orange root- root- stocks. In 1944 Dr. Batchelor put out the first field plantings, and six years later growers and nur serymen were propagating similar trees on a large scale. The two Troyer trees on the station have produced about 200 bearing progeny and probably half a million seedlings, Dr. Bitters estimates. From these seedlings have come rootstocks for an estimated 500,000 trees now growing throughout Califor nia and in other citrus areas of the United States. The larg est concentration of Troyer root- root- stocks is in Tulare County, where the variety's cold resistance is particularly usefuL
