The present study was conducted to standardize a suitable protocol
of in vitro plant regeneration potentiality of seven strawberry
varieties viz. AOG, JP-2, JP-3, Camarosa, Sweet Charly, Giant
Mountain and Festival. Young leaves, mature leaves and nodes of
seven strawberry varieties were used for callus induction and plant
regeneration. Among the seven strawberry varieties AOG was found to
be the most responsive genotype for primary culture establishment,
callus induction, shoot regeneration and rooting. A total of 40- 45
somaclones from each of the tested varieties were established and
maintained in the field and were considered as Ro plants. There
were no plants found resistance to fungal diseases but somaclones
showed better tolerence than the donor plants. Majority of plants
were found heat sensitive in donor plants but somaclones of AOG SC
3 showed better performance than other somaclones and donor parents
in terms of summer overcoming capacity. These somaclones can be
acceptable commercially if the good characters exhibited are
transmitted through generations or could be used in future breeding
programme for the improvement of strawberry varieties in
Bangladesh.
Taxonomic investigation of the family solanaceae growing through
out the Rajshahi University campus was carried out. A total of 8
(eight) species under 4 (four) genera of the family Solanaceae were
collected and identified. A complete taxonomic account of each
species is given with current nomenclature, local name, chromosome
number, flowering season and uses. All the species are distributed
all over the study area and the recorded species are(a) Solanum
nigrum, (b) Solanum spirale, (c) Solanum indicum, (d) Solanum
xanthocarpum, (e) Solanum torvum, (f) Datura metel, (g) Physalis
minima, (h) Nicotiana plumbaginifolia. Datura metel which is
sometimes cultivated and sometimes wild is grown in particular a
