Precocious Poncirus

Precocious Poncirus is early-flowering trifoliate-orange material also known as Fast Flowering Trifoliate. A Chinese research mutant was reported found in Yichang, Hubei, in 1976; the sources do not establish that the plants described by growers are that same mutant.^{⁠[1]⁠[2]⁠[4]}

Flowering and fruiting ages vary among reports. raregrowsnj describes flowering from about one year, fruit retention after two to three years, and repeated blooms. In the forum, one grower’s seedlings from Laaz had not flowered after about a year, while Sylvain reported flowering in 60% of his seedlings at about one and a half years without giving a sample count. These reports do not establish a guaranteed bearing age.^⁠[1]⁠[2]

Young and repeated blooms may provide pollen when other citrus flower, as suggested by raregrowsnj. Early flowers are not necessarily fully developed: Sylvain described small seedlings with immature flowers and absent or very small pistils. These observations do not establish crossing success or fertility for all precocious plants.^⁠[1]⁠[2]
