In order to obtain the information on the variations and genetic patterns of four quantitative characters of a rice cross in different environmental conditions, a cross of IG-65-1 × Pai-kan-kan-tao was used in this study.
為獲得水稻四數量性狀在不同栽培密度及氮肥量之環境下之變異及遺傳情形，乃利用IG-65-1 × 稗稈稻雜交組合為研究材料。在株高、穗數、穗長、和每株穗重之資料中發現，此四性狀在親本及F2族羣中，對環境之反應均不太相同。
