Abstract
Based on lint yield，bolls／plant，sin-gle boll weight，lint percent of the varieties thatjoined the Yellow River Valley Regional VarietyTest，according t0 the technique of harmonicanalysis，the author has built a long term predic-tion model to predict the developing trend of thenew varieties．As a result of agreement and ac-curacy examine，the agreement index is>0．90，the historical coincidence of the model reached1 00％，and its accuracy reached first-grade
(good) ,respectively. Forecast the varieties thatjoined in the 20-round-regional-test, the lintyield, bolls/plant, single boll weight and lintpercent reached 1209kg · hm-2,15.16boll/plant,5. 15g and 38. 55%, respectively. This studysupplied a new method for long term forecastingof the developing trend of cotton varieties.关键词
