臺農和秈糯2 號係由BG35-2 與IR29 兩品種雜交選育而成，本品種對稻熱病、白葉枯病、褐飛蝨具有抵抗性，其稻穀產量比臺中秈3 號一期作增產3.4 %，二期作增產31.9%。比紅腳糯一期作增產19.1%，二期作增產37.5%，平均每公頃稻穀產量，一期作為6.5 公噸，二期作為6.1 公噸。本品種之全生育日數一期作118 日，二期作94 日（兩期都比臺中秈3 號早熟10 日，比紅腳糯早熟7 日）株高一期作100 公分，二期作111 公分，株高雖較臺中秈3 號略高，卻不易倒伏，耐重肥栽培。每欉穗數約為14-15 穗，每穗重約2.7-3 公克，結實率約為90%，千粒重26.7-27.6 公克。
Rice variety Tainung Sen waxy 2, a selection from the cross of BG35-2 × IR29, was shown to resist blast, bacterial leaf blight and brown planthopper. The grain yield of this variety in the regional yield tests was 6.5t/ha in the first crop and 6.1t/ha in the second crop on a provincial average, which outyielded Taichung Sen 3 by 3.4% and 31.9%, for the first and second crops respectively. It also outyielded the variety of Hung-Chueh Waxy (an old and common waxy variety) by 19.1% in the first crop and 37.5% in the second crop. The total growing duration of this variety was 118 days in the first crop and 94 days in the second crop on a provincial average, or 10 days earlier than that of Taichung Sen 3, or 7 days earlier than that of Hung-Chueh Waxy for both the first and second crops. Although its plant height is higher than that of Taichung Sen 3, it was relatively tolerant to lodging and more favorably responsive to nitrogen fertilizer. In general, this variety is characterized by about 90% fertility rate, 14-15 panicles per hill, 2.7-3.0 grams per panicle weight and 26.7-27.6 grams per 1000-grain weight.
