“…The production of doubled haploid lines (DH) through anther culture is one of the fastest and most efficient approaches for producing high purity cultivars with enhanced traits, which has been well utilized in many plant species [29]. However, there are limited studies in camelina following this approach [30,31].…”

Camelina (Camelina sativa (L.) Crantz) is an emerging industrial crop from the Brassicaceae family, with its seed oil and cake being used for food, feed, and fuel applications. In this study, the relationships between economically important agronomic traits including seed yield (SY), days to maturity (DM), 1000-seed weight (TSW), seed protein content (PC), seed oil content (OC), and fatty acid composition in 136 doubled haploid (DH) camelina lines were investigated under rain-fed conditions in two consecutive years. There was prominent diversity among the studied DH lines for the agronomic traits such as seed yield, erucic acid, omega3, protein content, etc. Based on the Pearson correlation analysis of the data, SY was positively correlated with DM and OC, and negatively correlated with TSW, PC, and linolenic acid (C18:3) content. The positive relationships of the main characteristics, relevant to industrial applications, suggest the feasibility of developing new higher-yielding camelina cultivars with high seed oil content. The high seed yield of some camelina lines (DH044 and DH075) during the two growing seasons showed the potential of the lines. On the other hand, the contrasting genotypes for key traits in this study promised a favorable source to develop the superior breeding lines with higher seed yield and food/nonfood traits. Therefore, it can be concluded that the diversity of camelina DH lines traits is crucial for developing new cultivars. Furthermore, the present study reports some significant correlations among the DH lines, which may be useful for the current and future camelina breeding program.
