dc.description | Bangladesh has a glorious historical reference of growing cotton of superfine
quality cotton and it is one of the important cash crops. Cotton, being the king of
fibers in preparing human apparel plays a key role in the Development of
civilization. Due to its importance in agriculture as well as industrial economy, it is
also known as “white gold". It is mainly used in textile industries. There are more
than 140 spinning mills, over 280 weaving and over 60 dying and finishing mills
in the country, which consume 2.5 million bales of cotton (BTMA, 2010). Cotton
is an important fibre crop of global importance, which is grown in tropical and
subtropical regions of more than 80 countriestheworld over. It provides livelihood
to about sixty million people and is an important agricultural commodity providing
remunerative income to millions of farmers both in developed and developing
countries. Cotton provides raw material for various agro based industries like
ginning factories, oil mills, textiles industries which also provide employment to
thousands of people (Soomro, 2000).Generally, hybrid varieties exhibit high yield
performance over HYV. Xu and Fok (2007) reported that average seed cotton
yield of hybrid varieties was 3360 kg/ha and non-hybrid varieties was 3225 kg/ha.
Begum et al. (2005) found that, higher average weight of seed cotton/boll
increased the highest seed cotton yield. Boll size, boll wt. and fiber properties were
positively correlated with flowering date and boll retention (Fan et al., 1989). | en_US |
dc.description.abstract | A field experiment was conducted in Randomized Complete Block Design (RCBD) with
three replications in the experimental field of Department of Genetics and Plant Breeding,
Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh
during July 2013 to March 2014 to study the yield and yield contributing characters of 20
cotton inbred lines Tj....T29 . Different yield and yield contributing characters such as
number of vegetative branch, number of primary fruiting branch, number of secondary
fruiting branch, node number of fruiting branch days to 50% flowering, days to 50% ball
splitting. ball number per plant, plant height, ball weight and yield were studied.The
number of vegetative branch was significantly varied from 3.633 to 4.5. Among the
lines the maximum number of vegetative branch (4.5) was recorded in Tg line and the
minimum number of vegetative branch (3.633) was recorded in T; line. The maximum
number of primary fruiting branch number (13.63) was recorded in T,3 and Ty line
and the minimum number (11,03) was in T, line. The maximum number of secondary
branch numbers (12.37) were in T)7 line and the minimum secondary branch number
(9.3) were recorded in Tj line. The highest number of node for fruiting branch (7.37)
found in T29 line and the lowest number of node of fruiting branch (5.12) found in T;
line. Days to ball splitting were significantly different ranging from 101.3 to 118.1
days. The number of days required for ball splitting is significantly varied ranging
from 45.87 to 57.10 days. The highest balls per plant (25.23) was found in T)2 line
followed by Tis and Tj» line ( 24.9 and 26.83) respectively and the lowest balls per
plant (18.00) was found in T, line followed by T, inbred lines (19.33) respectively.
The ball weight was significantly varied from 4.333 to 6.35 g. The seed cotton yield
was significantly varied from 1812 to 2977 kg/ha. The highest seed cotton yield
(2977) found in T19 line and the lowest seed cotton yield (1812) in T, line. | en_US |
