Selection of Pityrocarpa moniliformis (Benth.) Luckow & R. W. Jobson mother trees for seeds production

Even though the growing demand for seeds of native forest species, both commercial and reforestation purposes, this sector still has some challenges large-scale production. Harvesting these frequently takes place in natural populations, areas not registered such use, considering sampling criteria that guarantee their genetic conservation. Due to economic socio-environmental importance Pityrocarpa moniliformis (Benth.) Luckow & R. W. Jobson, a species semiarid region Brazil, study aimed select mother plants P. seed production meets quality requirements demanded by conservation programs. To end, from 44 trees were subjected evaluation physical physiological aspects as well diversity progenies using ISSR molecular markers. There was considerable variation on seeds, where 77% produced with germination above 50%. The progeny test showed 64.4% source total loci comes progenies, indicating an increased difference between generations. By phytosanitary aspect, yield (800 seeds/individual) viability (> 50%), (Nei distance < 0.78 test), it possible 27 superior characteristics are important parameters selecting producing intended commercialization, access assists aiming at recovery degraded areas, breeding. Seed-producing can be selected based individuals seeds.
