摘要: Significant differences in vitro digestible organic matter (IVDOM) were found between plants of diploid Agropyron cristatum (L.) Gaertn. and tetraploid A. desertorum (Fisch.) Schult. Narrow-sense heritabilities for IVDOM ranged from 0.36 to 0.76. showed no relationship plant height, forage yield lodging percentage, but was significantly correlated with leaf percentage. Diploid strains more palatable than tetraploids superior IVDOM. A sharp decline dry (IVDDM) occurred heading the end anthesis little thereafter. Approximately 1 wk prior anthesis, IVDDM crested wheatgrass similar that bromegrass (Bromus inermis Leyss.), at subsequent stages inferior. It concluded limited progress breeding quality possible using testing.
