1. The work was oarriod on Chiayi Experiment Station cooperation with Central Agriculture Research Bureau at 1949-1951.
2. The paper deals with a study on the apaptation of the twenty-six improved rice varieties by the regional test.
3. The materials of the test were choson by Central Agriculture Experiment Bureau. They were divided into two series according to their growth-day, nineteen varieties as an early-rice namely series. and seven as median-rice, namely series C. Two native varieties were selected as cheek.
4. The average yields of the two varieties Yüin-Lien-Chan (筠連粘)and Chung-Nung-No. 4. (中農4號) in the lst crop of series B. and those of the ten varieties Chung-Nung-No. 4. (中農4號), Yüin-Lien-Chan (筠連粘), Si-Lih-Kuh (細粒谷), Tsao-Ho-No. 4. (草禾4號), Mao-Tzu-Tou (帽子頭), Chung-Nung-No. 34 (中農34號), Yüh-Lih-Chou (玉粒早), Fu-Mien-Huang (富綿黃), Chung-Chien-No. 2. (中黔2號) and Shui-Peh-Tiao (水白條) in the 2nd crop of the same series are higher than the average yield of the check according to the analysis of three-years-six-crops-records. The yields of two varieties Chiangsi No. 3613 (江西3613) and Yung-An-Leng-Shui-Peh (永安冷水白) in the 1st crop of series C. and those of four. varieties Yung-An-Leng-Shoi-Peh (永安冷水白), Chiangsi No. 3613 (江西3618), I-Liang-Ta-Peh-Kuh (宜良大白谷) and Chechang-Chung-Sien No. 1 (浙場中秈1號) in the 2nd crop of the same series also reached the level. All the difference of the average yields among above varieties are very significant.
5. The yield of variety Victory (勝利秈) of the series B. does not reach the level, bet it average yield per hectare of lst crop has been over 4,000kg. However, it is lower in the 2nd crop. This shows us that it may be used as a good variety in the lst crop. The yields of other varieties such as Chou-ho-No. 4. (早禾4號) and Mao-Tzu-Tou (帽子頭) are lower in 1st crop but higher in 2nd crop thus they are adapted in 2nd crop.
6. In series C, the yields of variety I-Liang-Ta-Peh-Kuh (宜良大白谷) has been lower in 1st crop but higher in 2nd crop. Therefore, it must be adapted in 2nd crop as a good variety.
7. According to the analysis of varience between the yields, the varieties which can be adapted to the lst and 2nd crops in both series are Yüin-Lien-Chan (筠連粘) Chung-Nung No. 4. (中農4號), Chiangsi-No. 3613 (江西3613) and Ung-An-Lâng-Shui-Peh (永安冷水白). Victory (勝利秈) is most adapted in 1st crop. Si-Lih-Kuh (細粒谷) Chou-Ho No. 4. (早禾4號), Mao-Tzu-Tou (帽子頭) and I-Liang-Ta-Peh-Kuh (宜良大白谷) adapted in 2nd crop under the weather condition of Chiayi.
8. The distance between rows and plants of the experiment employed in these experiments seems rather large. If we take the closer planting distance which are popularly used by the rice-farmers of Taiwan, the yield of the above mentioned varieties per unit would be increased.
9. The above nine improved varieties may be selected to extend as good varieles of native rice (在來種), after regional test.
