One tree budded on sour orange in 1942 was 8 feet tall with a 7-foot spread at 10 years of age. It is fairly open with flowering habits like the kumquat. Fruits are round to pyrifoem, ranging from 1 1/2 to 3 inches in diameter, and orange yellow when ripe. The interior of the fruit is lemon-like, has a pleasant acidity, and becomes sweeter in March and April. It is highly cold-resistant, and the remarkably uniform seedlings develop rapidly. Swingle considered this variety as a probable hybrid of Meyer lemon and kumquat." (Mortensen, 1954) "'Lemonquat' (TR 26) is a chance hybrid found at Beeville and tested at Crystal City, Texas...The 'lemonquat' has value for backyard culture in areas where standard lemons are injured by cold, since it has acid fruit, is cold-hardy, and blooms several times a year. It can be propagated as cuttings." (Olson and Sleeth, 1965) "The fruit of this Lemonquat are very similar to those of Sunquat which suggests to us that this is another mandaquat (perhaps it has Clementine or Dancy tangerine as a parent). Circa 1981, Chapman suggested such a possibility and Mortensen agreed that the Rio Grande Valley Lemmonquat could also be a mandaquat." (Loeblich and Walden, 1993) At the time of donation, Dr Loeblich reiterated his belief that this accession is probably a "mandaquat". Olson and Sleeth (1965) recommend as a rootstock 'Cleopatra' mandarin or calamondin. (RRK, 08/2007) | 1734086 | PI 654885 |
| 1 | PI 539831 | 'Rangur X Troyer' | Citrus sp. | California, United States | RIV | | | 1990 | DEVELOPED | 1954 | | | | | Rootstock | This accession was developed at the US Date and Citrus Station and apparently sent to Florida (presumably the USHRL) at some point. It was re-imported into California by CCPP as a promising rootstock in the late 1980's, apparently at the request of Mike Roose. "M Roose reports that this is a desired rootstock and may be needed for industry trial release here [California]. Tentative plan is to process for the variety collection...foundation set + CB at Lindcove. M Roose also [says] that this accession is Phytophthora resistant to a degree." (EM Nauer, 04/1988) "In the nursery it produces vigorous, unbranched seedlings which are easy to bud. Seedling tests indicate that it is more susceptible to Phytophthora parasitica than Carrizo, but survival of field trees has been excellent. It is resistant to tristeza but susceptible to exocortis...Soil adaptation is not yet well characterized, but it has grown well on a wide rnage of soils in Florida...[Trees] gornw on [this accession] have a moderate growth rate resulting in trees 50 - 75 % of the height of those on Carrizo. We believe its overall effect on tree size will be simialr to that on C-35 citrnage. Yield relative to tree size is good to excellent in most trials [as is fruit quality]. Trees on this cultivar also showed moderate cold tolerance under Florida conditions. Ocerall it appears to be a rootstock worth of trial in higher density plantings. On the other hand it has not known advantages over C-35 citrange and somewhat poorer disease resistance."
