Cilantro in Mexico is consumed fresh and the cultivated varieties are of foreign origin, and there are no reports of germplasm with high oil content that can be used in the industry. The objective was to evaluate phenotypically, morphologically and biochemically seven advanced coriander lines with desirable agronomic characteristics for production of fresh biomass and oil. Under a design in complete blocks at random the lines L9-CB, L13-CB, L17-CB, L21-CB, L25-CB, 29-CB and INIFAP-17 were sown. The agronomic management was carried out according to Gonzalez et al. (2017). The phenotypic, morphological and biochemical characters in plant and seed were determined. The best material for fresh production was the INIFAP-17 line for its greater number of basal leaves (31), fresh biomass (221 g) and long vegetative period, while for seed production the best lines were L9-CB (1.12 g pta-1) and L13-CB (1.16 g pta-1) are an option. The oil content of the advanced lines analyzed (6.21 to 11.23%) was higher than that reported in the literature (3-5%). Petroselinic acid was the majority with a concentration between 68.95 and 73.51 g 100 g-1 of oil, followed by linoleic acid (14.2 - 18.55 g 100 g-1 of oil). From a nutraceutical point of view, coriander oil presented an oleic/linoleic (O/L) ratio of less than 1. It is of interest to identify germplasm with a higher content of linoleic acid because the O/L ratio greater than 1 helps to prevent certain diseases.

Keywords : coriander; fatty acids; fresh biomass; genetic improvement; oil.
