Development of new perennial oil crops for marginal environments productivity of Lesquerella mendocina under different nitrogen availability

Naturalized populations of Italian ryegrass (Lolium multiflorum Lam.) grow in different environments in Buenos Aires Province (Argentina). Juvenile plants of a cultivar and 20 populations collected in central-east areas of this Province were analysed in two environments with different soil types (Argiudol and Natracuol). At each site, 40 plants per plot were transplanted isolated, in a complete randomized blocks with three replicates. Morphological and agronomic traits were registered and ANOVA between environments were performed, with the replicates nested in the environments, and the genetic determination grade (GDG) was estimated. With the data registered during the trial as well as other previously obtained for the same populations, the affinity among populations was calculated by multivariate analysis. The genotype × environmental interaction resulted negative only for plant diameter and dry matter production as a result of the poor variation of the populations in the Natracuol soil type. Differences among populations and between environments in the majority of the characters were detected and the GDG was low to medium. The best performance was detected in Argiudol soil as a result of the limiting conditions of the Natracuol soil on the populations. Cluster analysis of the data in each environment showed differences in the affinity of the populations. The provenance of the most different populations was in the periphery of the area collected, while the ones distributed in the central area presented an affinity superior to 50%. Principal components analysis and the minimum spanning tree contributed to establish the affinity of the populations.
