水稻雜種弱勢基因Hwc-1, Hwc-2之表現及其利用之研究－I. Hwc-1, Hwc-2基因對農藝性狀之影響及台灣水稻品種之基因型探討

Abstract

水稻為自交作物，但栽培種仍有0~6%的天然雜交率，為預防花粉污染，黑糯稻等有色品種，被列為不鼓勵、不輔導的品種。雜種優勢廣泛地被研究與利用，而雜種弱勢之研究雖偶可見，但鮮有其利用之報告。 As a self-pollinated crop, 0-6 % natural pollination rate were still observed in the cultivated rice, Oryza sativa. To prevent the pollen contamination, the colored rice such as red and black waxy rice varieties were neither encouraged nor introduced to the farmers.
