Abstract: This work analyzed the fat composition and the fatty acid composition of ten Carya illinoensis (pecan)cultivars by using gas chromatography and a correlation analysis. Results showed that fat content between 69.11%-78.19% for all pecan kernels,including palmitic(C16:0),stearic(C18:0),oleic(C18:1),linoleic(C18:2),linolenic(C18:3),arachidic(C20:0). And kernel content of the seed ranged from 36.79%-59.49%. Fatty acid content was greater than 90.00% with oleic and linoleic percentages having a significant negative correlation(r = -0.994 2,P<0.01). For pecan oils,the correlation analysis showed significant differences(P<0.05)in the fatty acid contents. The mono unsaturated fatty acid(MUFA) content of the fat was 73.01%-58.76%;the polyunsaturated fatty acid(PUFA) content was 32.20%-19.69%. Also,oil yield and shelling percentage had a significant positive correlation(r= 0.674 0,P<0.01);whereas,rate of seed and peel thickness was not significant.[Ch,3 fig. 3 tab. 12 ref.]
