摘要: Rueda Krauss, O. M.S., Purdue University, May 2014. Parent tree selection and evaluation of frost resistance, wood quality seed relatedness Acacia koa. Major Professor: Charles H. Michler. This project represents an important effort to develop improvement program for a valuable native hardwood species in Hawai’i, The ultimate goal the is provide improved stock A. koa through classical breeding, focusing mainly on stem form. In addition, assessment young trees try markets pre-commercial thinning. also clarifies some trends related resistance fluctuations over different seasons Hawai i. main questions that were addressed are: Which are best families maintain order convert HARC A plantation into orchard? Do heritability estimates change depending taken account compute them? selected show significant differences resistance? Does fluctuate between seasons? What characteristics trees? And finally, how closely seeds within legume? experiments conducted Big Island i at stand Mana Road eastern slopes Mauna Kea. site managed by Department Hawaiian Home Lands (DHHL).
