| 0 | PI 651861 | 'KX2-Hawaii' | Leucaena hybr. | Hawaii, United States | | | Historic | 2007 | DEVELOPED | | | | | | Cultivar | Arboreal tropical legume to a height of 15m that was bred largely as a forage crop, to be browsed or harvested periodically (8-16 wks). Distinguished from the parent species by leaf and leaflet morphology, flower head size and color, and pod and seed size. For each of the 5 cycles of selection, ~ 1500 trees were planted and coppiced repeatedly over a period of 2-3 years, selecting the outstanding 100+ trees as seed parents. Is resistant to the psyllid, to which its L. leucocephala parent is susceptible, and grows vigorously under cold temperatures that dwarf the L. leucocephala parent. Forage yields are treble those of the L. pallida, a highland Mexican species (also 2n=104) chosen for its resistance to the psyllid, tolerance of cold weather, and its self-sterility. The population is derived from seed orchards in which only self-sterile trees are retained, but due to segregation of S alleles there will be some self-fertile trees in the population. Orchardists are encouraged to rogue out self-fertile trees, to reduce seediness and potential invasiveness while improving fodder and wood yield. | 1744969 | PI 651861 |
| 1 | PI 647963 | 'KX2-HAWAII' | Leucaena hybr. | Hawaii, United States | S9 | | | 2007 | DEVELOPED | 2007 | | | | | Cultivar | Open pollinated population representing 5 cycles of recurrent selection from hybrids made in 1976. KX2 hybrids were extremely vigorous vegetatively, with the large leaves and smaller leaflets of the pallida parent. For each of the 5 cycles of selection, ~ 1500 trees were planted and coppiced repeatedly to allow selection based on the following major criteria: psyllid tolerance, forage regrowth vigor and self-incompatibility. Seediness is an undesirable trait associated with the highly self-fertile common variety of L. leucocephala, and led to our emphasis on self-sterility. Approximately 120 trees were selected each cycle to serve as seed parents, and panmixia can be assumed. Seeds of cycle 3 of selection were distributed internationally after 1991 to confirm the durability of psyllid tolerance. Seed production of the selected progenies from cycle 5 was completed in 2003 and current seed is derived from two seed orchards at the Waimanalo Research Station on Oahu, Hawaii. | 1726037 | PI 647963 |
