Abstract/ Executive Summary:

Twenty six lines of B. rapa having brown seed coat colour along with one check as BARl Sarisha-9 were evaluated without replication under Observation Trial of B. rapa (Set-II) at Joydebpur. Maturity duration ranged from 88-95 days. BARl Sarisha-9 was the earliest in maturity (88 days). Seed yield ranged from 1261-2411 kg/ha. The highest seed yield recorded in BC-11219315(3)-4 (2411 kg/ha).

Keywords: Brassica rapa, Agronomic traits, 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:

Twenty six lines of B. rapa having brown seed coat colour were selected last year from F₆ generation of different cross combinations. These lines along with one check as BARl Sarisha-9 were evaluated without replication under Observation Trial of B. rapa (Set-II) at Joydebpur during 2013-14. The lines were sown on 14 November 2013 in 2 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 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.

Achievement/Findings:

Variations were observed among the lines for all the characters studied. Maturity duration ranged from 88-95 days. BARl Sarisha-9 was the earliest in maturity (88 days). Plant height ranged from 89-125 cm, No. of siliquae/plant ranged from 74-172. No. of seeds/siliqua ranged from 8-21. The highest no. of seeds/siliqua recorded in BC -11219315(6)-4. Thousand seed weight ranged from 2.78-4.06 g. Seed yield ranged from 1261-2411 kg/ha. The highest seed yield recorded in BC-11219315(3)-4 (2411 kg/ha).
