高粱育種研究

Abstract

為育成釀酒用高粱品種，進行糯性高粱純系選種作業，選拔表現9 個性狀表現優良品系，春作高粱品系間株高分布為100~171 cm，穗長分布為26~33 cm，百粒重分布為1.4~2.4 g；秋作糯性高粱株高分布為100.1~124 cm，屬中矮性品系；穗長分布為24.7~33.7 cm，屬中短穗長品系；百粒重分布為2.1~2.4 g；牧草用高粱有17 個品系表現良好，具有在臺灣栽培潛力，將持續進行栽培觀察試驗。 In order to breed sorghum varieties for wine making, 9 good lines of pure waxy sorghum were selected. The spring-cropped sorghum lines were 100-171 cm in plant height, 26-33 cm in spike length, and 1.4-2.4 g in 100 seeds weight. The autumn-cropped sorghum were 100.1-124 cm in plant height, 24.7-33.7 cm in the spike length, and 2.1-2.4 g in 100 seeds weight. There were 17 lines of forage sorghum performed well, which have the potential for cultivation in Taiwan. Those lines will continue to conduct cultivation observation experiments.
