In the present investigation, 30 different potato genotypes were evaluated for 3 consecutive years. The estimates of different components of variation and coefficient of variability, such as phenotypic, different interaction and error were more or less high for yield, number of leaves/plant, number of tubers/plant and number of eyes/ tuber, which indicates the wide scope of improvement of these traits through selection. The highest of h2b was recorded for tuber yield and lowest in number of tubers/plant.Path coefficient analysis showed that potato genotypes could be grouped into 6 different...

Present study was under taken with a view to improve the yield potential of indigenous (local) potato varieties (IPVs). Six IPVs viz., Lal Shill, Patnai, Shill Bilati, Lal Pakri, Sada Gutti and Challisha were selected as experimental materials. These IPVs are popular among the potato growers of the Northern part of Bangladesh because of their high value due to high culinary quality and storability. In the present study three in vitro techniques viz., i) heat treatment followed by meristem culture for the development of virus free planting materials; ii) induction of microtuber for rapid...

Strawberry is very delicious fruit. It is not native to Bangladesh. Present study shows that the high incidence of somaclonal variations among the plants regenerated through callus phase that could be used in breeding programmes for improvement of strawberry. These somaclones were distinct from each other in terms of fruit and other horticultural characters, and have potential for commercial cultivation in Bangladesh. The RAPD profiles were generated through the amplification of the genomic DNA, extracted from the leaf samples of three selected variants and control plants, with fifteen random...

Cultivable land scarcity is a major limitation for horizontal increase of food production for the future food security of the world. Potato is the most energy efficient crop in terms of yield and nutritional values that can contribute vertical increase in food production for insuring food security in the world. Keeping this notion in mind the present research work was undertaken with a view to improve potato in both quantitative and qualitative attributes. In the present study the following research issues were addressed: i) improvement of tissue culture technology for the production of high...
