Physiological characterization of four model Lotus diploid genotypes: L. japonicus (MG20 and Gifu), L. filicaulis, and L. burttii under salt stress by Melchiorre, Mariana, Quero, Gastón E., Parola, Rodrigo, Racca, Roberto Walter, Trippi, Victorio, Lascano, Hernan Ramiro

“…These results suggest that enhancement of antioxidant responses in Lj MG20 contributed to improve salt stress tolerance at early stages. On the other hand, after long-term high NaCl stress treatment, L. filicaulis exhibited lower biomass reduction, lower oxidative damage and Na+ accumulation in leaves than the control treatment; hence, this genotype was considered salt-tolerant. …”

Statistical models for the detection of genes controlling quantitative trait loci expression by Carbonell, Emilio A.

“…Many important traits in plant breeding exhibit continuous variation (yield, maturity, biotic and abiotic stress tolerance, etc.). The genetic principles underlying their inheritance are basically the same as those affecting Mendelian or qualitative traits, but since the segregation of the genes concerned could be followed individually, new methods and concepts had to be developed. …”
