ABSTRACT - Genetic improvement programs of perennial forage legumes in Brazil evaluate accessions in row plots without considering the genetic variability within accessions. Individual plant evaluations would not only allow for selection of the best accessions but also for the best individuals within accessions. This procedure is however more labor-intensive and expensive. The effectiveness of using the simulated individual BLUP selection method (BLUPIS) was assessed in a trial with Stylosanthes capitata and S. guianensis in a completely randomized block design with 35 accessions, six plants per plot and six and five replications, respectively. The method can be applied when only total plot yields are measured and provide selection at the individual plant level. Results showed a high correlation between selection by the traditional BLUP and the alternative BLUPIS methods. The latter is recommended for improving species in which individual plant evaluations are difficult. |

This study aimed to select and characterize Bacillus thuringiensis strains with toxic activity on Helicoverpa armigera, Spodoptera cosmioides and Spodoptera eridania. Fifty B. thuringiensis (Bt) strains were used in selective bioassays for high mortality on H. armigera, and the four most efficient strains were tested on S. cosmioides and S. eridania. Twelve Bt strains were characterized by PCR to detect some cry, cyt and vip genes. Bioassays were also performed to detect the production of beta-exotoxins. Strain 237 caused a mortality rate of 95.6% due to beta-exotoxins. Strains 1368, 1521, 1814 and 3299 showed toxic activity on S. eridania. However, no strain was effective on S. cosmioides. The presence of beta-exotoxin was detected only in strain 237. The molecular characterization of the strains using specific cry, cyt and vip primers showed a great genetic diversity among the 12 strains that showed some mortality on H. armigera and S. eridania. Our results showed that detecting beta-exotoxin in Bt strains is important as it is toxic to insects and vertebrates and persistent in the environment. Strains 1368, 1521, 1814 and 3299 did not show toxicity to H. armigera, while they were toxic to S. eridania and did not produce beta-exotoxin. These strains may be useful for new formulations of biopesticides as well as for cloning and expression of plants' genes. |
