Abstract: Studies were made on the agronomic characteristics, variety type and wide compatibility of 14 rice varieties introduced from America. Pedigree analysis were also conducted. The results indicated most of varieties have unfavourable comprehensive characteristics. Low number of effective panicle per plant is a main problem. Different variety have advantage in different characteristics. 14 WCVs which include varieties with compatibility gene and varieties from indica-japonica hybridization were identified. Pedigree analysis demonstrated that the genetic base of 20 WCVs can be traced to these varieties: Pachain, UNJP, Marong paroc, Hill sel., UNPH, Hnduras and so on. It is essential to make further studies on morphological feature and physiological property of American varieties and genetic base of wide compatibility.

Key words: American rice variety, Agronomic characteristics: Pedigree analysis: Wide compatibility
