An extensive survey on the quality of rice in Taiwan was conducted in 1967. Forty-nine samples of twenty three varieties in first crop and thirty-three samples of twenty-two varieties in second crop were collected from every district and chemical analyses were made on the brown rice. The results were shown in Table 1-2.
A same phonomenon, as got in 1966, was observed in this year. The extremely high amylose ratio and higher protein content were detected with the native rice again.
The quality of rice, so far as amylose ratio and protein content concerned, is prince-pally affected by its variety; even so, there were some effects observed with locality, for instance, the rice produced in northern district had higher amylose ratio and protein content.
Although the amylose ratio correlated with protein content, comparing the data obtained in these two years, it was expected that the amylose-amylopectin ratio should be mainly influenced by the quantity of soluble solid.
By screening with variety and locality, just thirty samples of twenty varieties were selected both from first and second crops, and a Table for comparison is presented as Table 5. With these thirty samples, significant correlationships were secured between protein and the other constituents, namely, starch (-), ash (+) and amylase-ratio (+) correlate with protein, respectively.
