영문 초록

This experiment was carried out to evaluate the agronomic stability of North Korean rice varieties using the statistical model developed by Grafius, Finlay, and Ever-hart. The lowest yearly variation based on coefficients of variation was found in Hannam 29 for number of panicles per in Sijoong 9 for number of grains per panicle, in Pyeongyang 3 for ripened grain ratio, in Sijoong 16 for 1,00(] grain weight, and in Yeomju I for grain yield. By Grafius’s model, Pyeongbook 3, Weonsan 66 in early matur-ing groups and Seohaechalbyeo in medium maturing groups show stable for 3 years. Weonsan 66 in early maturing groups and Seohaechalbyeo in medium maturing groups were found to be highly stable as analyzed by both Finlay and Wilkinson’s model and Everhart & Russell’s model. With reference to three models, Weonsan 66 was highly stable for 3 years with showing more yield than Odaebyeo in early maturing groups while Seohaechalbyeo was highly stable for 3 years with showing high yield than 1Vaseongbyeo in medium maturing groups above 5 t ha·1 of milled rice respectively.
