Cytological Studies on Polyploids Derived from Tetraploid Fragaria Vesca and Cultivated Strawberries.
REVIOUS workers have obtained hybrid seedlings from diploid Fragaria P vesca x cultivated strawberry, but they were always sterile so that new types never became established. -4 colchicine-induced autotetraploid of F. vesca L. (DERMEN and DARROW 1938) when used in a series of crosses with the octoploid cultivated strawberry ( x F. ununassa Duch.) has given hybrids varying in fertility from comp...

متن کاملGenome Physical Mapping of Polyploids: A BIBAC Physical Map of Cultivated Tetraploid Cotton, Gossypium hirsutum L
Polyploids account for approximately 70% of flowering plants, including many field, horticulture and forage crops. Cottons are a world-leading fiber and important oilseed crop, and a model species for study of plant polyploidization, cellulose biosynthesis and cell wall biogenesis. This study has addressed the concerns of physical mapping of polyploids with BACs and/or BIBACs by constructing a ...
متن کاملSurvey of simple sequence repeats in woodland strawberry (Fragaria vesca).
The use of simple sequence repeats (SSRs), or microsatellites, as genetic markers has become popular due to their abundance and variation in length among individuals. In this study, we investigated linkage groups (LGs) in the woodland strawberry (Fragaria vesca) and demonstrated variation in the abundances, densities, and relative densities of mononucleotide, dinucleotide, and trinucleotide rep...
متن کاملEngineering the anthocyanin regulatory complex of strawberry (Fragaria vesca)
The woodland strawberry, Fragaria vesca is a model fruit for a number of rosaceous crops. We have engineered altered concentrations of anthocyanin in F. vesca, to determine the impact on plant growth and fruit quality. Anthocyanin concentrations were significantly increased by over-expression or decreased by knock-down of the R2R3 MYB activator, MYB10. In contrast, a potential bHLH partner for ...
