Characteristics and Evaluation of Self-cross Progenies of Fragaria viridis Duch.
Morphological traits of five self-cross progeny accessions of Fragaria viridis Duch.were observed.Variation among five self-cross accessions and F.viridis was assessed.Of all 67 biological traits,42 with significant differences were obtained including soluble solids.15 traits were conducted by principal component analysis and variation coefficient analysis,and the result showed that plant height,plant size,pedicle length,pedicle thickness,inflorescence thickness,and pollen vitality provided the key indicators for diversity of self-cross progeny accessions and F.viridis.A significant difference of self-cross fruit setting rate was found among five self-cross accessions,and Ls-S1-4 was the lowest.The research would lay the foundation for self-compatiblity/incompatibility of F.viridis.
