| dc.description | Mungbean (Vigna radiata L. Wilczek) known as green gram is one of the most important
food grain legume crop all over the world. It belongs to the sub-family Papilionaceae
under the family Leguminosae. Vavilov's was listed "Central Asiatic Centre" as a primary
centre of origin for mungbean. This crop is regarded as quality pulse in Bangladesh for its
excellent protein quality (20-28.4%), high digestibility and freedom from flatulent effects
associated with other pulses e.g., chickpea and lentil. (Hoque et al., 2007) The demand for
this crop has been steadily increasing at present situation. However, this crop is
characterized by low yield potential. Several biotic and abiotic factors as well as low
genetic variability are supposed to be responsible for lowering the production of this
important crop. In some growing seasons losses exceed more than 50% due to incidence of
many pest and diseases (Poehlman, 1991 and Bose, 1991). It is cultivated most extensively
in India, Myanmar, Bangladesh, Sri-Lanka, Pakistan, Thailand, Philippines, China, Japan,
Korea, Iran, Indonesia, parts of East and Central Africa, West Indies, USA and Australia.
The genus Vigna currently includes around 80 species distributed throughout the tropics
(Pasquet, 2001). | en_US |
| dc.description.abstract | The experiment was conducted at the experimental field and in the tissue culture
laboratory of the Department of Genetics and Plant Breeding, Hajee Mohammad
Danesh Science and Technology University, Dinajpur during July to November
2009. Four genotypes of mungbean (Vigna radiata L. Wilczek) BARI Mung-2,
BARI Mung-4, BARI Mung-5 and BARI Mung-6 were used in these
experiments. Flower biology was studied for days to first flowering, total number
of pollens under 100x microscope, number of fertile pollen, number of sterile
pollen, pollen fertility (%), pollen sterility (%) and yield/plant (g). The characters
significantly varied in genotypes. BARI Mung 6 was the highest performing
genotype for all the positive characters which enhance seed yield. Yield and yield
attributes were assessed through correlation study. Yield was significantly
correlated with number of fertile pollens and pollen fertility (%). Regeneration of
mungbean was conducted with four genotypes of mungbean and different
concentrations and combinations of hormones (2,4-D, NAA, BAP and IAA) were
used to assess regeneration ability by using two explants (leaf and cotyledon).
Regeneration potential was high from leaf explants for all genotypes. Highest
percentage of callus was observed in hormonal combinations of MS+0.5mg/I 2,4-
D, MS+0.5mg/1 2,4-d+0.5mg/1 BAP and MS+1.0mg/l 2,4-D+0.5mg/1 BAP with
BARI Mung 6. A combined effect of Ts (MS+10.0mg/l Kn) with BARI Mung 6
showed highest performance in shoot regeneration. For root induction a combined
effect of Ty (MS+ 0.1 mg/l IAA) with BARI Mung 6 showed highest
performance. Among the four genotypes BARI Mung 6 was found to be effective
for regeneration of mungbean. | en_US |
