Aromatic rice varieties are of traditional type. These indigenous rice cultivars are low yielding but their higher price and low cost of cultivation generate superior profit margins compared to other rice varieties. Several biotic and abiotic factors are believed to be responsible for the low yield potentials of these varieties of Bangladesh. In addition to the conventional breeding methods, biotechnological techniques can be applied in overcoming such constraints. But limited information is available regarding the improvement of these rice varieties through biotechnology. In...

This book reports the potential of using the entomopathogenic fungus, Metarhizium anisopliae, as a bio-control agent of ticks. The efficacy of M. anisopliae conidia formulated in either oil or water, in inducing mortalities to various developmental stages of ticks is reported. Various stages of Amblyomma hebraeum, Amblyomma variegatum, Rhipicephalus appendiculatus and Rhipicephalus evertsi evertsi were found to be highly susceptible to M. anisopliae in water and oil formulation. Fungal conidia were protected with chemical sunscreens, Everysun(r) and E45(r), respectively, and exposed to UV...

Gerbera has gained popularity and great demand in the floral industry as cut flower due to its beauty, color, long vase life. Its propagation can be increased by applying the modern biotechnological methods such as tissue culture for rapid and large scale propagation. For a modern and industrialized horticulture there is always a demand and necessity for new varieties. Induced mutations have proven to be the most rapid, direct and cheapest approach to develop new and attractive flower or ornamental plant varieties. In total 552 mutant varieties of 40 ornamental plant species were released...

Jute is considered as one of the most important natural fibre of the tropical and subtropical regions of the world. Although there has been a decline in the volume of trade, jute is still considered as one of the most important foreign currency earner of many jute growing countries including Bangladesh. The production, quality and yield of this crop are affected by various biotic and abiotic stresses. The higher production and quality jute fibers can be obtained through the development of improved varieties using conventional as well as biotechnological techniques. But conventional breeding...
