Analysis of adaptability and stability in soybean elite lines - DOI: 10.4025/actasciagron.v26i3.1838 Agronomy
Vicente, Dorival; Pinto, Ronald José Barth; Scapim, Carlos Alberto.
The effects of genotype x environment interaction (GxE) on the stability and adaptability of 9 soybean (Glycine max (L.) Merrill) elite lines and one control (IAS 5) were studied in 11 locations in the States of Paraná, Rio Grande do Sul, São Paulo and Mato Grosso do Sul, during the 2000/01 and 2001/02 crop seasons. A complete randomized block design, with three replications, was used in all environments. Significant differences for the effect of genotypes, environments and interaction GxE were observed for grain yield. Statistical models followed the standard method, ecovalence, Eberhart and Russel, Cruz, Torres and Vencovsky and AMMI methodologies. Genotypes CD 97-922 and CD 98-3118 were responsive under unfavorable environments. Lines CD 97-1243, OC...

Mapping and validation of molecular markers of genes Dt1 and Dt2 to determine the type of stem growth in soybean Agronomy
Vicente, Dorival; Schuster, Ivan; Lazzari, Fabiane; Paranzini, Jonas Pedro Dolfini; Oliveira, Marco Antonio Rott de; Prete, Cássio Egídio Cavenaghi.
The type of stem growth in soybean is a distinguishing feature of cultivars. The genes Dt1 and Dt2 affect the termination of the stem, and the types of growth are classified as determinate, semi-determinate and indeterminate. Phenotypic characterization of the type of growth is complex and is occasionally erroneously described. The objective of this study was to map and validate molecular markers to classify the type of soybean growth to facilitate the description of cultivars and genotypic selection. Two populations were used for mapping and validation of molecular markers F2:3: T 117 (semi-determinate growth type) x Igra RA 518 RR (indeterminate growth type) and CD 235RR (determinate growth type) x Igra RA 518 RR. The study demonstrates that the...
