Abstract

Among the various methods employed towards rice improvement, the one by "introduction" is by far the easiest and most rapid method. Varieties from Japan, Korea, Italy, America and China were given a fair trial in our country. From among the reports by rice workers, it could be gathered that none of these, except a few Chinese varieties was found to adapt themselves to the conditions existing in India. The study of the behaviour of Chinese varieties also opened the line of introducing desirable genes into indica varieties. In this paper, the details of a trial aimed at directly introducing Chinese varieties in Thanjavur delta are presented.
