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 کاملRegeneration and Agrobacterium-mediated transformation of three economically important strawberry cultivars Kurdistan, Camarosa and Paros
Genetic transformation studies were carried out to standardize a protocol for Agrobacterium -mediated genetic transformation of three economically important strawberry (Fragaria x ananassa Duch) cultivars Kurdistan’, Camarosa’, and ‘Paros’. Shoot regeneration frequency 72, 65 and 30% was obtained on MS (1) basal medium supplemented with 2% glucose and 4 mg/l TDZ for Camarosa, Kurdistan and Paro...
متن کاملGenetic and Environmental Regulation of Flowering and Runnering in Strawberry
Cultivated strawberry (Fragaria × ananassa Duch.) is one of the most important berry crops worldwide. Its wild relative, woodland strawberry (Fragaria vesca L.) is also scientifically important, since recent development of molecular tools including genetic transformation methods, genetic maps and genome sequence is making it as one of the leading perennial model plants. Environmental regulation...
متن کاملCharacterization of T-DNA integration sites within a population of insertional mutants of the diploid strawberry Fragaria vesca L
Cultivated strawberry (Fragaria × ananassa) is an octoploid (2n=8x=56) species that belongs to the Rosaceae family and the high ploidy level makes genetic and molecular studies difficult. However, its commercial success because of its unique flavor and nutritious qualities has increased interest in the development of genomic resources. Fragaria vesca L. is a diploid (2n=2x=14) species with a sm...
متن کاملCHARACTERIZATION OF POLYMORPHIC MICROSATELLITES IN STRAWBERRY AND THEIR TRANSFERABILITY TO OTHER GENERA IN THE ROSACEAE FAMILY By
We investigated the transferability of 20 Fragaria vesca microsatellite primer pairs to 13 Fragaria vesca accessions, six Fragaria species and ten commercially important species in Rosaceae. Genetic diversity studies were carried among 16 diploid Fragaria accessions using these polymorphic microsatellites. The average number of alleles amplified for a polymorphic locus was 4.7 with maximum bein...
