Abstract
1. 將臺灣育成之水稻品種，共96種，以酒井氏方法計算其與臺中65號．及秈型稻之親緣係數，同時計算現有主要栽培品種，11種，相互間之親緣係數。
2. 96品種內有79品種與臺中65號有血緣關係，其中72品種之親緣係數分佈於 25~55%之間。與秈型稻有血緣關係者有65個品種，其中有55個品種之親緣係數分佈於5~25%之間。
3. 11個主要栽培品種相互間之親緣係數，均與各品種與臺中65號之親緣係數成正比。臺北306號與各品種極少有血緣關係。
1. Coefficients of relationship between each of 96 varieties and Taichung No. 65, as well as the indica varieties were computed by Sakai’s method. Besides, the coe-fficients of reciprocal relationship of ten leading cultivated varieties were also calculated.
2. Seventy nine varieties were found to have the relationship with Taichung No.
65 in 96 varieties studied, and most of their coefficients distributed from 25 to 55 percent. Meanwhile, 65 varieties have the relationship with indica type varieties and their coefficients were found frequently between 5 to 25 percent.
3. Coefficients of reciprocal relationship of ten leading cultivated varieties were observed to positively correlate with those coefficients between the each of ten and Taichung No. 65. Taipei No. 306 is the only one variety which has less relationship with another varieties including Taichung No. 65.
