Popis:	Infestation by Chilo plejadellus Zincken of 100 rice lines varied from 0 to 98%, with the commercial variety ‘Saturn,’ used as a check, having- 75% of the stems damed. Statistical analysis of the data showed 55 lines were damaged significantly less than Saturn. Lines maturing both earlier and later than Saturn were damaged less than Saturn. Certain lines had significantly fewer stems damaged than Saturn, and also allowed the development of significantly fewer larvae. Moreover, 18 lines which were damaged as heavily as Saturn had significantly fewer larvae than Saturn.
