加工用楊桃雜交後裔選拔

Abstract

本試驗利用現有優良甜味種與酸味種進行正反雜交，採用人工授粉，自然受粉及混植受粉等三種方法實施，計進行19個雜交組合，所得實生後裔單株定植1,290株，培育成活984株。經二年之產量及品質分析調查，初步選得較優良實生後裔且適合楊桃果汁加工之單株有10～27和10～36等二個新品系。 Good horticultural characters of sweet and sour carambola varieties were used as experimental materials for breeding and selection of new juice processing varieties. Crossing were conducted by means of artificial pollination, natural pollination and mixed planting pollination. Totaled 19 cross combinations were obtained and 1290 progenies seedlings were planted. There were 984 plants survival after planting. Single plants with goog horticultural characteristics derived from sexual seedlings of 2 breeding lines, namely 10~27, 10~36 and have been selected based on 2 years of yield record and quality analysis.
