| dc.description | To evaluate the stability of the trait resistance to insects, under different dates of planting, three resistant and three susceptible genotypes were tested in an experiment set up at the experimental station of the Centro Nacional de Pesquisa de Soja (Soybean National Research Center), Embrapa, in Londrina, PR, Brazil. The study consisted of soybeans planted at six different dates, starting on 18 October and spaced ca. 15 days from each other. At harvesting, height of plants, height of first pod, indexes of lodging and leaf area retention were evaluated. Seeds of three meters of row were harvested and of another three meters were harvested one week later. Results indicated that delay of harvesting did not significantly increase stink bug damage to seeds. The best seed quality were observed on soybeans planted between November 15 and December 15. The highest and lowest yields were obtained on soybeans planted on November 30 and October 18, respectively. Early maturity genotypes showed lower yields when planted up to November 15, the medium group had the lowest yield when planted at October 18, while late genotypes yield less when planted at October 18 and at both December dates. An interaction between genotypes and dates was observed both for yield and quality of seeds, indicating the need of identifying sources of resistance to stink bugs with more stable behavior. | |
