Abstract/ Executive Summary:

Ten promising lines and three released varieties of Corchorus olitoirus were evaluated to determine their superiority over late jute seed production. The study was conducted at central agriculture research station, Manikgonj during the period 2005-2006. Varieties/lines differed greatly from each other in respect of plant population per square meter, number of pods per plant, number of seed per pod and seed weight per square meter and sowed wide range of variability. Number of pod per plant was highest in variety O-9897 followed by SDLT1, A4311 and O-72 but number of seed per pod was highest in Br-L while seed weight was highest in Br-O and was higher in O-9897. Higher and similar seed weight were also observed in variety O-72 and Br-L but number of pod per plant, number of seed per pod and seed yield per square meter of this variety were not higher then other two varieties O-9897 and Br-O. Plant height and base diameter did not showed direct relation with seed yield.

Location: At Central Agriculture Research Station, Manikgonj

Start Date: 15-03-2005

End Date: 15-06-2006

Program Area: Variety and Species

Commodity: Jute

Objectives:

To evaluate of some promising breeding lines of tossa jute (Corchorus olitorius L.) specially for seed production

Methodology:

Three varieties of C. olitorius namely, O-9897, O-72 and OM-1 and ten advanced lins Br-O (Brown seed with ovate glossy leaves), Br-L (Brown seed with ovate lanceolate glossy leaves) BU-O (Blue seed with ovate glossy leaves) BU-L (Blue seed with ovate lanceolate glossy leaves) pedi. 7/95 (Red), pedi. 11/95-2, A-4311, SDLT1 (short day and low temperature tolerant), SDLT2 and SDLT3 of C. olitoriusspecies where grown at central agriculture research station, Manikgonj during the period of 2005-2006 for late seed production. The experiment was conducted in a Complete Randomized Block Design. Each variety was sown in 2 decimal areas. The inter and intra row spacing were 30 cm and 5cm respectively. Standard dome of fertilizer was applied and followed normal agronomic practices. Plants from one square meter area were collected from each variety and line at 130 DAS. Sample plant were taken to the laboratory and data were recorded for plant population, plant height, base diameter, number of pod per plant, number of seed per pod, green weight of plant and seed weight. Standard deviation and co-efficient of variation were calculated.

Achievement/Findings:

Varieties/lines differed greatly from each other in respect of plant population per square meter, number of pods per plant, number of seed per pod and seed weight per square meter and sowed wide range of variability. Number of pod per plant was highest in variety O-9897 followed by SDLT1, A4311 and O-72 but number of seed per pod was highest in Br-L while seed weight was highest in Br-O and was higher in O-9897. Higher and similar seed weight were also observed in variety O-72 and Br-L but number of pod per plant, number of seed per pod and seed yield per square meter of this variety were not higher then other two varieties O-9897 and Br-O. Plant height and base diameter did not showed direct relation with seed yield.
