Adaptive Trial of Advance Durum Lines

Chief Scientific Officer & Head, OFRD and Relevant Scientists of OFRD, BARI

Abstract/ Executive Summary:

Among the tested genotypes, the maximum days to maturity (120 days) was recorded in E5 and the minimum (116 days) in E2, E4 and E8. Genotype E1 performed better and produced the highest grain yield (3.08 t ha^-1) due to maximum number of grain spike^-1 (39.65) and 1000 grain weight (38.9 g). Lowest yield (2.78 t ha^-1) was obtained from E7.

Keywords: Durum lines, Farmers’ fields, Yield

Location: Farmers’ field of Faridpur

Start Date: 00-00-2014

End Date: 00-00-2015

Program Area: Variety and Species

Commodity: Durum wheat

Objectives:

To evaluate the performance of new durum lines in AEZ-12 under farmer’s conditions before release as variety.

Methodology:

Performance of eight durum lines marked as E1, E2, E3, E4, E5, E6, E7 and E8 were evaluated at the farmers’ field of Faridpur during Rabi, 2014-15. The trial was laid out in RCBD with two compact replications. Unit plot size was 2.4 m x 5 m (12 rows x 5 m. long). Two adjacent unit plots were separated by 50 cm and 1 m space was given between the blocks. The land was fertilized with 105-28-50-20-0-1.5 kg of N-P-K-S-Zn-B ha^-1. The full amount of P, K, S, Zn and B were applied as basal during final land preparation. Two-third of N was applied as basal and remaining one-third N was top dressed at 21 days after sowing (DAS). Seeds were sown on 7 December 2014. Two irrigations were given at 21 and 60 DAS and one hand weeding was done at 37 DAS. The crop was harvested on 5-9 April 2015. Data were recorded on days to heading and days to maturity, spikelet sterility (%), grain spike^-1, spike m^-2 and seed yield. Ten plants were collected prior to harvest from each plot after attaining maturity to collect data on yield attributes. Yield data was recorded from an area of 5 m². The collected data were analyzed statiastically.
