| 摘要： 利用育種方法，選育品質佳或適合外銷需求之蓮霧、芒果、棗、番石榴、木瓜等品種推廣種植或改進栽培方法，提高品質及產量，有利提高農友收益。為選育優良品種，本試驗乃以人工及天然雜交工作。所獲得之雜交種子則培育成實生苗，進行2年觀察試驗。選得之果實大、可溶性固形物高、櫥架壽命長等之優良品系，則選供品系比較試驗之用。入選之優良品系則進一步於各主產區進行區域試驗。根據區域試驗之結果，選得之優良品系將供命名及推廣用。Selection of better quality or suitable traits for exportation purposes in wax apple, mango, Indian jujube, guava and papaya through breeding for planting, or cultural practice improvement in increasing the quality and yield will be beneficial for increasing the farmers income. For breeding and selection of superior varieties, the artificial and natural crosses will be applied in this experiment. Hybrid seeds obtained from different cross combinations will be propagated as seedlings for the two-year observations. Lines with large fruit size, high total soluble solid content, and long fruit shell life etc. will be selected as materials for line test. Superior lines selected from line test will be further tested by regional yield trial at major production sites. From the results of regional yield trials, the selected lines with good performance will be registered as new cultivar and then for extension. |
