Patterns of variation and correlation among traits in a strawberry germplasm collection (Fragaria × ananassa Duch.).

摘要: In this paper evaluating variation of twenty-eight traits in a strawberry collection consisted 117 accessions (clones), and assessment phenotypic, genotypic environmental correlations among these have been carried out. The genotypes studied were part the germplasm established Research Institute Pomology Floriculture Skiemiewice, Poland. evaluated include attributes growth, development, yield, fruit quality resistance to most important diseases. These observed on one plot for each genotype during three fruit-bearing seasons from 2001 2003 using rate scale 1 9 or rarely 7 (larger scores trait determine larger level its expression according definition). input data arranged an incomplete two-way x year classification (some only two years). Variance components estimated separately by REML method random model VARCOMP procedure SAS software package. Coefficients heritability three-year phenotypic means basis variance components. Genetic covariance needed estimation different correlation coefficients MANOVA option GLM
