Abstract/ Executive Summary:

Fifteen lines of B. rapa having yellow seed coat colour along with check as BARl Sarisha-14 were evaluated without replication at Joydebpur. BC-2014-09 was the earliest in maturity (83 days) followed by BC-2014-08 (84 days). The highest seed yield recorded in BC-2014-15 (2218 kg/ha). Considering earliness, seed yield and other yield contributing characters, five lines BC-2014-01, BC- 2014-02, BC-2014-03, BC-2014-05 and BC-2014-09 were selected for the next trial.

Keywords: Brassica rapa, Yielding lines

Location: Joydebpur, Gazipur

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Variety and Species

Commodity: Mustard

Objectives:

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

Methodology:

Fifteen lines of B. rapa having yellow seed coat colour were selected last year from F₆ generation of different cross combinations. These lines along with check as BARI Sarisha-14 were evaluated without replication under Observation Trial of B. rapa (Set-I) at Joydebpur during 2013-14. The lines were sown on 14 November 2013 in 3 rows of 3m long with spacing of 30cm and 5cm between rows and plants, respectively. The seedlings were thinned after few days of germination 5 cm 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.

Achievement/Findings:

Variations were observed among the lines for all the characters studied. Maturity duration ranged from 83-94 days. BC-2014-09 was the earliest in maturity (83 days) followed by BC-2014-08 (84 days). Plant height ranged from 77-113 cm, The check variety BARI Sarisha-14 showed lowest plant height (77 cm). No. of siliqua/plant ranged from 66-144. No. of seeds/siliqua ranged from 12-28. The highest no. of seeds/siliqua recorded in BARI Sarisha-14. Thousand seed weight ranged from 2.7-4.2g. Seed yield ranged from 1200-2218 kg/ha.
