Abstract/ Executive Summary:

Eighteen lines/genotypes of Brassica rapa having yellow seed coat colour along with two checks as BARl Sarisha-l d and Local Tori-7 were evaluated at Joydebpur, Jessore and Ishurdi. The highest seed yield was recorded in BC-100614(4)-2 at Joydebpur location. Maturity duration over locations ranged from 80-88 days. Check variety Local Tori-7 was the earliest in maturity. Lines BC- 100614(4)-13 and BC-100614(4)-11 took 85 days to mature and BARl Sarisha-14 took 84 days to mature over locations. Seed yield ranged from 1257-2436 kg/ah over locations. The line BC- 100614(4)-2 produced the highest seed yield over locations and it also produced the highest seed yield at Joydebpur location and higher yield at Jessore and Ishurdi locations. Check variety Local Tori-7 produced the lowest seed yield over locations.

Keywords: Brassica rapa, Yield, Agronomic traits

Location: Joydebpur, Jessore and Ishurdi

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Crop-Soil-Water Management

Commodity: Mustard

Objectives:

To select short duration high yielding lines with better agronomic traits.

Methodology:

The experiment was conducted at Joydebpur, Jessore and Ishurdi during rabi 2013-14 with 18 genotypes of Brassica rapa having yellow seed coat colour along with two checks as BARI Sarisha- 14 and Local Tori-7. The experiment was laid out in randomized complete block design with two replications. The plot size was 3m x 0.9m. Seeding was done on 13 November at Joydebpur, 08 November at Jessore and 5 November at Ishurdi 2013 in continuous sowing and row was 30 cm apart from each. The seedlings were thinned after few days of germination 5 em apart. Fertilizers were applied @ 120:80:60:40:4: 1 kg/ha of N:P:K:S:Zn and Boron from Urea, TSP, MP, Gypsum, Znic Sulphate and Boric acid respectively. Half of the urea and all other fertilizers were applied during final land preparation. The rest of the urea was applied at flower initiation stage. All intercultural operations were done timely to raise a good crop. Data were taken on days to flowering, days to maturity, plant height (cm), primary branches per plant, siliquae per plant, seeds/siliqua, 1000 seed weight (g) and yield per plot. The plot yield was converted into kg/hectare. The data were analyzed statistically.

Achievement/Findings:

All the characters studied showed significant variation except no. of siliquae/plant. Maturity duration ranged from 79-88 days. Local Tori-7 was the earliest in maturity. Plant height ranged from 78-96 cm. The lowest plant height was recorded in Local Tori-7. Siliquae/plant ranged from 68-116 which was non significant. Seeds/siliqua ranged from 17-36. The highest no. of seeds/siliqua was recorded in BC-100614(4)-2 which was statistically similar with other fifteen lines and lowest in check variety Local Tori-7. Thousand seed weight ranged from 3.0-4.0 g. Seed yield ranged from 1337-2426 kg/ha. The highest seed yield was recorded in BC-100614(4)-2 which was statistical I similar with other eleven lines. The lowest seed yield was recorded in Local Tori-7.
