The biological characteristics of Pleurotus cultivars in the southwestern region of Viet Nam were conducted by morphology, molecular phylogeny, spawn running and biological efficiency. Total 10 Pleurotus cultivars were belonged to 5 morphotypes as following: 5 cultivars GTG1, GBT1, GBT2, GVL1, GVL3 belonged to phoenix type, 2 cultivars WSG1, WVL1 belonged to oyster type, a cultivar YVL1 belonged to golden oyster type, a cultivar PVL1 belonged to pink oyster type, and a cultivar DgSG1 belonged to blue oyster type. By morphological and phylogenetic analysis, all 5 phoenix cultivars were identified to P. pulmonarius, both 2 oyster cultivars and a blue oyster cultivar were P. ostreatus, a golden oyster cultivar was P. citrinopileatus, and a pink oyster cultivar was P. djamor. By the model of 1.2 kg rubber tree sawdust in nylon bag, the spawn running of golden oyster cultivar (12.47±1.20 mm/day) and pink oyster cultivar (11.29±1.00 mm/day) was higher than all phoenix cultivars, and the spawn running of blue oyster cultivar was lowest (6.57±0.76 mm/day).ETC...
