摘      要：Madhuca latifolia *** known as Indian butter tree,is an open-pollinated *** in seed and oil yields depends on the progress in the desired characters in the base material and the genetic variability available in the collected *** evaluated 23 genotypes of *** to understand genetic variability,character association and divergence in seed traits and oil content for use in breeding *** was recorded in seed length（27.3–38.6 mm）,seed breadth（15.6–19.1 mm）,two dimensional（2D） surface area（328.3–495.4 mm2）,100 seed weight（216.8–285.3 g）,acid value（13.4–25.8 mg KOH/g）,iodine number（62.4–78.6） and oil content（37.8–51.0 %）.High estimates of genotypic coefficient of variation,broad senseheritability and genetic gain were observed for seed oil *** studies for seed traits revealed that genotype CPT-16 had the highest 100-seed weight（281.5 g） and oil content（51 %）.Highly significant genotypic and phenotypic correlations were ***100-seed weight was positively and significantly correlated with oil content at both phenotypic（r = 0.57） and genotypic（r = 0.60） *** analysis of the scores of the first three principle components（80.83 %） resulted in four clusters,consisting of 4,7,3 and 9 genotypes in the first,second,third and fourth clusters,*** 3was distinguished from others based on significantly higher means for most seed traits except seed breadth,acid value,iodine number and oil *** 1 appeared more divergent as it had significantly higher means for acid value and iodine number.A comparative assessment of means of the four clusters for 100-seed weight and oil content suggested that cluster 3 would be useful for higher 100-seed weight and oil *** these genotypes,CPT-3,CPT-6 and CPT-15 in cluster 3 can be used for direct selection and utilization in breeding programs.
