荔枝育種之目標為育成不同產期，高品質大果無子，豐產之品種，育種方法包括自然授粉實生選種及人工控制授粉雜交育種，實生苗種植行株距建議以3×0.5公尺為佳。現已蒐集30餘品種，以Peroxidase及Glutamate oxaloacetate transaminase 同功異構梅分析可區分成七大類。實生品系中已選5品系，於本省六地進行試作，本文並就育種方法及其效率增進之可行加以分析討論。龍眼育種以不同產期，大果無子、矮性品種為目標，育種方法同荔枝，目前已蒐集40餘品種，依其成熟期（7-11月）可區分成5大類，並已進行自然授粉實生品系選拔。
Litchi (Litchi chinensis Sonn.)breeding for various mature season, quality(large and seedless fruit), and yield were conducted through open and controled-pollination. The spacing of 3×0.5m were suggested to handle large population of seedlings. Thirty collected varieties could be classified into 7 groups sccording to isoayme analysis of peroixdase and glutamate wxaloacetate transaminase. Five clones selected was adv- anced to regional yield trail at 5 locations in Taiwan. The methods and efficiency of breeding was discussed. Longan (Dimocarpus longan Lour.) breeding for various mature season, large and seedless fruit and dwarfness were started via germplasm collection Forty varieties were maintuined and classified into 5 groups according to mature season (July to November). Selection of seedlings from open-and controled-pollinati on have been conducted and will be continued in breeding program.
