Correlation and path analysis on the yield characters of a Japonica Xi- giant embryo -1 was studied under three different cultivation regimes of submerged irrigation, dry. cultivation and ridge cultivation. The results indicated that grain yield of the ridge cultivation was 24.33% higher than that of the submerged irrigation. The ridge cultivation was favorable to make an ideal grain yield components, and significantly promoted effective panicles, spikelets per panicle, seed setting rate and 1000-grain weight. Dry cultivation significantly decreased grain yield and its components. Effective panicles, spikelets per panicle, seed setting rate and yield have significantly （0.01） obvious positive correlation, 1000-grain weight and yield has significantly （0.05）obvious positive correlation; on the contrary, effective panicles and spikelets per panicle, effective panicles and 1000-grain weight, spikelets per panicle and 1000-grain weight have weak negative correlation. Therefore, ridge cultivation were beneficial to increase the grain yield and its components, when drafting the measure of high-yield cultivation for the Japonica Xi-giant embryo-1 in Production, and we should enhance the moisture management of paddy, not only increase the 1000-grain weight, but also main attack and mix up effective panicles and spikelets per panicle.
