Abstract
The study aimed to compare 29 brown mustard genotypes for their agronomic and oil yield traits under fall sowing conditions of Yenimahalle and Ikizce locations (Ankara) during 2017-2018. The result showed significant differences among the genotypes and the locations. Means of the two locations showed oleic acid, linoleic acid and erusic acid in range of 7.42 to 24.54%, 5.81 to 23.97% and 20.87 to 50.25% in the same order. The highest crude oil yields of 124.3 g plot-1 and 123.9 g plot-1 were obtained for AK and A3 genotypes, at Yenimahalle and Ikizce locations, respectively. Among the genotypes, AK (427.6 g plot-1) and A3 (373.0 g plot-1) genotypes exhibited outperformance with maximum seed yield and was recommended for further evaluation and use in biofuel production industry.
Highlights
Brown mustard (Brassica juncea L.) is an annual plant cultivated worldwide for the industrial oilseed, spice, vegetable and fodder crop species
Thousand seed weight may contribute information to seed yield, that vary among genotypes
Brown mustard (B. juncea L.) genotypes evaluated in this study exhibited an important level of diversity for seed yield, crude oil content, crude oil yield, crude protein content and fatty acid compositions
Summary
Brown mustard (Brassica juncea L.) is an annual plant cultivated worldwide for the industrial oilseed, spice, vegetable and fodder crop species. The study aimed to compare twentynine brown mustard genotypes for their important agronomic characters under fall sowing conditions of hot humid continental climate of Yenimahalle and warm temperate climate of Ikizce locations agro climatic conditions during 2017-2018 growing season in Ankara, Turkey. All genotypes were planted as a fall sowing in the experimental fields located at Yenimahalle location 39°57′ 20.776′′N, 32°48′ 49.154′′, and 925 m altitude, with hot humid continental climate – Köpen Geiger Dsa type and Ikizce 39°26′ 18.87′′N, 32°22.691′′, and 1050 m altitude, with warm temperate climate – Köpen Geiger CSb type climatic characteristics under semiarid climatic ecological rainfed conditions.
