Abstract
Bangladesh Jute
Research Institute (BJRI) has recently released an early maturing high yielding
jute variety having better quality fibre of Corchorus
olitorius L. in the year 2013 namely “BJRI Tossa Pat 6”. It was previously
isolated through anatomical study as a breeding line (O-3820) from the origin
of Kenya. The line, was evaluated for time of sowing, days to flowering, yield
and other morphological attributes. Advanced yield trials were also conducted for
two years (2008 and 2009) along with on-firm yield trials for three consecutive
years (2010 to 2012) at Manikganj, Faridpur, Chandina, Kishoreganj and
Monirampur stations. After trials, it was observed to be suitable for late
sowing and fit for existing cropping pattern in late seeding areas of Bangladesh.
The variety had characteristics of flowering within 130-135 days when sown on
30 March. It was observed to be high yielding which is at par with the existing
best varieties O-9897 and BJRI Tossa Pat-4 along with higher fibre compactness.
It matured earlier than the existing varieties, and could be sown 15 days
earlier than existing photosensitive variety O-4. It bearded non-shattering pod
characteristics and observed to be tolerant to some insect, diseases and pests
such as mite, apion, stem rot and especially nematode. Potential yield of the
variety was found to be about 5.0t ha-1 by maintaining the
plant population 3.5-4.0 lac. ha-1. However, the average yield was
observed about 3.0 tha-1, which was 7.16 % higher than the existing O-9897.
Key words: BJRI Tossa Jute-6,
early maturing, quick growing variety.
