Genetic, phenotypic, and environmental correlations in black medic, Medicago lupulina L., grown in three different environments

摘要: We have investigated the relationship between phenotypic and genetic correlations among a large number of quantitative traits (36) in three different environments order to determine their degree disparity whether could be substituted for counterparts whatever environment. also studied influence environment on correlations. Twenty accessions (full-sib families) ofMedicago luPulina were grown environments. In two these levels environmental stress generated by harvesting plants at flowering growing competition with barley, respectively. A third environment, no treatment, was used as control stress. Average values pod shoot weight indicate that induces highest level The 36 compared. Significant obtained easily, while there variation 1 or 2 characters being correlated. positive correlation matrices indicated good proportionality but not similarity. given when only those significant variance taken into account, still differences correlations, even significance lowered. Consequently, it is dangerous substitute showed variability increased increasing stress, consequently contrast, influnced structures both matrices, however, depended same way matrices.
