| dc.description.abstract | An experiment was conducted to study the morphological and yield characters with five
genotypes Choto Bombay onion (control), Big Bombay onion, Special Bombay onion, Uz-1 and
Uz-2 onion at the research farm of Sylhet Agricultural University, Sylhet from November 2013
to July 2014 with a view to select the suitable genotypes based on higher yielding abilities in
acidic soil condition. The experiment was laid out in a Randomized Complete Block Design
(RCBD) with three replications. The experimental field was divided into three blocks
representing three replications and each block had five individual plots with five genotypes that
are evaluated on the basis of morphology and yield characteristics. Choto Bombay Onion
(control), Two Indian cultivars namely Special Bombay Onion and Big Bombay Onion were
collected from seed market at Dhaka while another two cultivars Uz-1 and Uz-2 were collected
from Uzbekistan. Results revealed that high yielding genotype was Uz-2 which had highest in
bulb fresh weight. The genotype Uz-2 was maximum in Bulb fresh weight, leaf sheath diameter,
root fresh weight and bulb diameter and had contain highest moisture content. The genotype Uz1
onion
was
maximum
in
leaf
blade
diameter,
leaf
blade
length,
leaf
blade
fresh
weight
and
root
fresh
weight
whereas
bulb
length,
bulb
dry
weight,
leaf
sheath
length,
leaf
sheath
dry
weight
and
leaf
blade
dry
weight
was highest recorded in Special Bombay Onion. In maximum parameter
Choto Bombay onion was lowest except leaf sheath length, root fresh weight, leaf sheath fresh
weight, root dry weight, bulb dry weight and leaf sheath dry weight. Considering yield and yield
contributing characters Uz-2 can be selected as the best genotype for Sylhet region. | en_US |
