Conteúdo: | The two main strategies employing somatic hybridization used at the Citrus Resesarch and Education Center (CREC) in Florida are a combination of existing rootstocks that exhibit complementary traits into allotetraploid somatic hybrids (SH), or wide hybridization of Citrus with related genera in efforts to expand the hybrids (SH), or wide hybridization of Citrus with related genera in efforts to expand the germplasm base for citrus improvement. The SH produced are currently being evaluated for disease, nematode, and pest resistance, and commercial rootstock potential. The SH produced from [sweet orange +lemonl parentage are consistently showing Phytophthhora resistance. SH resistant to quick-decline caused by citrus tristeza virus include [sour orange + Rangpur], [sour orange + Volkameriana (zygotic)], and [sour orange + Carrizo citrange]. SH with Fortunella, Citropsis, Atalantia, Microcitrus, and Citrus ichangensis parentage are significantly more resistant to Radopholus citrophilus than the susceptible sour orange control.
