- Abstract
[Objective] To select the elite germplasms with the method combining both grade and factor evaluating so as to provide references for the collection and breeding of elite chestnut germlasms. [Method] Sixty-three germplasms, including local varieties and elite individuals, were collected in NorthernYanshan Mountains and taking the chestnut cultivar ‘Yanshanzaofeng ’ sample as the control. The ranking of quality assessments for different germplasms was determined by grade evaluating method and the factor evaluating method with the following physiological indexes: fresh weight, water content, starch, soluble sugars and soluble proteins, compared with those in ‘Yanshanzaofeng’. [Result] Among these germplasms, the average weight of single fresh seed was 8.7 g, while the maximum was 13.6 g and the minimum was 6.5 g. The average water content was 42.9%, while the maximum was 50.7% and the minimum was 37.6%. The average soluble sugar content was 9.8%, while the maximum was 17.1%and the minimum was 4.8%. The average starch content was 34.3%, while the maximum was 58.6% and the minimum was 17.4%. The average soluble protein content was 0.56%, while the maximum was 1.1% and the minimum was 0.16%. [Conclusion] There are significant differences in fresh seed weight, water content, starch, soluble sugars and soluble proteins among the seeds from different chestnut germplasms. These quality indexs could be used as indicators for the evaluation of the elite germplasms. The elite germplasms estimated through the combination of the graded scores and the factor analysis in this study will provide references for the collection and selection of the elite chestnut germplasms.
