水稻品種臺農69號是由F3(臺農61M5 10-14/Oryza rufipogon)//臺農62號之雜交後代選出。第一期作比臺農67號低產4%-5%,第二期作高產8%-19.3%。在全省性區域試驗比臺農67號減產4%-7%。本品種有相當廣幅又穩定的稻熱病抵抗性,同時亦抗細菌性白葉枯病,並共具臺農67號相似之紋枯病忍耐性。臺農69號不但抗褐飛蝨1、2、3生理型、也抗白背飛蝨並受斑飛蝨之害亦較緩漫。本品種的米質、株高、抽穗期等特性與臺農67號相似,但稻稈稍軟不如臺農67號耐倒伏,故其肥料反應也稍差。
Rice variety Tainung 69 is a selection from the progenies of a cross between F3 (Tainung 61 M5 10-1^4/Oryza rufipogon) and Tainung 62. It yielded lower than Tainung 67 by 4%-5% in the first crop but outyielded it by 8%-19.3% in the second crop. In regional tests, Tainung 69 gave an yield of 4%-7% lower than Tainung 67 in average. It is resistant to a wide range of blast pathogen including that at IRRI, Philippines and is also resistant to bacterial leaf blight disease. It exhibited a tolerance to sheath blight disease similar to Tainung 67. Tainung 69 was found resistant in the tests to brown planthopper biotypes 1, 2 and 3, and also to the white-hacked planthopper. It showed a slower progress in the damage caused by small brown planthopper. The plant height, days to mature and rice quality of Tainung 69 are similar to those of Tainung 67, but its straw is not as stiff as that of Tainung 67, hence the fertilizer response is slightly poor.
