超級雜交稻在台灣的產量潛力分析

水稻為台灣最主要生產與消費的糧食作物，開發高產品種一直是水稻育種重要目標之一，其中雜種優勢運用是一可行的方向。本研究以大陸地區引進之「錢優0508」 (‘Qianyou 0508’； ‘QY 0508’)、「II 優7954」 (‘II You 7954’; ‘II Y 7954’)、「Y 兩優689」(‘Y Liangyou 689’; ‘YLY 689’)、「Y 兩優302」(‘Y Liangyou 302’; ‘YLY 302’)、「皖稻153」(‘Wandao 153’; ‘WD 153’)、「五優308」(‘Wuyou 308’; ‘WY 308’)、「株兩優168」(‘Zhuliangyou 168’; ‘ZLY 168’) 等7 個秈型超級雜交稻組合為材料，對照品種為台灣秈稻純系品種「台中秈17 號」 (‘Taichung Sen 17’; ‘TCS 17’)，在台灣地區進行一年兩期作生育特性及產量潛力評估試驗。 Rice is the most widely grown and consumed staple crop in Taiwan. Increasing rice yield potential is eventually a major target in rice breeding programs and the use of heterosis is also a feasible strategy. The objective of this study was to evaluate growth characters and yield potential of the recently developed hybrid rice in Mainland China. Field trials were conducted for two cropping seasons using seven Chinese varieties including ‘Qianyou 0508’ (‘QY 0508’), ‘II You 7954’ (‘II Y 7954’), ‘Y Liangyou 689’ (‘YLY 689’), ‘Y Liangyou 302’ (‘YLY 302’), ‘Wandao 153’ (‘WD 153’), ‘Wuyou 308’ (‘WY 308’), ‘Zhuliangyou 168’ (‘ZLY 168’) and check variety ‘Taichung Sen 17’ (‘TCS 17’).
