Abstract
The seeds of wild Crambe species have potential to be used as a source of industrial oil and animal feed. In this study, 48 genotypes of three Crambe species collected from the flora of Turkey were grown under field conditions in Ankara/Turkey in 2014–2016. The seed protein ratio, plant height, number of branches per plant, number of seeds per plant, seed yield per plant, thousand seed weight and hulless/hulled seed ratio (H/H) were determined. The highest protein ratio was determined as 26.02% in the t18 accession of Crambe tataria species. Variations in the characteristics were analyzed using principal component analysis. In the factor analysis of Crambe maritima, Crambe orientalis, Crambe tataria and the mean of these three species, the first two principal components accounted for 100%, 58.06%, 59.93% and 100% of the total variations, respectively. There were positive correlations between the plant height and number of seeds per plant, seed yield per plant for C. orientalis, and number of branches per plant for C. tataria. Although seed yield per plant was high in C. tataria and C. orientalis, they are not suitable for conventional agriculture due to shell thickness, inhomogeneous plant emergence and shooting. Conventional cultivation of wild Crambe species can be made possible by eliminating these negative features with breeding and agronomic studies.
Highlights
The genus Crambe, which is a member of the family Brassica, comprising 338 genera and 3709 species, has approximately 35 taxa worldwide [1]
Among the Crambe species, the average plant height (PH) was highest in C. orientalis (132.33 cm) and lowest in C. maritima (79.05 cm)
The average branches per plant (BPP) was highest in C. orientalis (14.57 branches) and lowest in C. maritima (9.17 branches)
Summary
The genus Crambe, which is a member of the family Brassica, comprising 338 genera and 3709 species, has approximately 35 taxa worldwide [1]. The flora of Turkey includes six species and four infraspecific taxa [2], comprising Crambe alutacea Hand.-Mazz., C. tataria. Tataria, C. grandiflora DC., C. hispanica L., C. maritima L., C. orientalis L. subsp. Like many members of the family Brassica, the genus Crambe is a new potential plant that could be a source of industrial oil [1]. The majority of Crambe species can be cultivated to provide high crop yields. They can be used as melliferous, starch-bearing green fodder, or as decorative plants [5]. The oil obtained from Crambe abysinica has high erucic acid content and has been used as an antiadhesion in the nylon and plastics industries
