UFR-3 is a new and distinct allotetraploid citrus rootstock for tree size control and improved disease resistance. UFR-3 has shown a positive reaction to the Huanglongbing disease (HLB, or citrus greening disease) in multiple experimental field trials. Scion trees grafted on this rootstock show a reduced frequency of infection and reduced disease symptoms once infected as compared to commercial diploid rootstocks.

A new mandarin tree named AC4916 notable for its flavorful seedless fruit.

A new and distinct cultivar of Citrus plant named N40W-5-1, characterized by small to medium, nearly seedless fruit with a unique and robust sweet flavor; compact growth habit; flavorful juice; and fragrant fruit with a smooth rind. The new Citrus cultivar also is more tolerant to HLB than most mandarin varieties, especially when trees are supplemented with controlled release fertilizer (CRF) containing an enhanced micronutrient package.

A new and distinct cultivar of lemon plant named CE-D5-1-9-42, characterized by nearly seedless fruit, early fruiting, and high fruit production. Additionally, the new lemon cultivar also is compatible with trifoliate orange rootstocks, unlike most lemon varieties. This new cultivar has high quality fresh fruit, as well as juice, peel oil, and other lemon by-products viable for processing. Further, given the new lemon cultivar's good HLB tolerance typical of lemons, and its near seedlessness, this new cultivar may have significant dooryard tree potential.

A new and distinct seedless, easy to peel mandarin hybrid, named RES 19-56, with a unique clustered fruit bearing habit that can appeal to citrus hobbyists as an ornamental, but that also has shown potential value for premium early season fresh market production by CUPS or other Citrus growers. Has shown the ability to set large numbers of parthenocarpic fruit in the CUPS production system. These clusters sometimes number 15 or more fruit, having many more than fruit per cluster than other seedless mandarin hybrids.

A new and distinct seedless, sweet orange-mandarin hybrid, with distinctive shape and color, that can be harvested through a season extending for at least three months. The new citrus cultivar, named UF 1859, also appears to be more tolerant to HLB than most mandarin varieties, showing standard leaf, foliage, and fruit morphology and dense foliage despite being CLas positive.

A new variety of citrus Mikanken4 that has dark orange fruit color, without seeds, high juiciness, orange-like flavor, ease of peeling the fruit by hand, good appearance, and good tasting qualities.

The disclosure relates to novel disarmed Agrobacterium tumefaciens strains, uses of these disarmed Agrobacterium strains, and kits comprising such disarmed Agrobacterium strains. The disarmed Agrobacterium strains are effective for the transformation of plant, fungal, or algae cells. The Agrobacterium strains are very effective for the transformation of citrus plant cells.

A new variety of Citrus sp. plant named Mikanken10 that has dense spines on the tree, leaf blade with emargination at tip, fruit with flattened general shape of distal part, and no navel opening.

A new variety of Citrus sp. tree HAYASE that has medium tree habit in-between upright and spreading, spindle-shaped leaf blade with acuminate apex and acute base, vestigial wing, fruit with high diameter/height ratio (average 1.31) and medium to heavy weight (average 152.3 g), no neck, a flat distal part, bright orange (JHS 1305) skin color, thin peel thickness, easy to medium peeling, deep orange (JHS 1307) color when fresh, juicy when fresh, high sweetness, very few seeds, early maturity, and low acidity.
