Developing yellow passion fruit cultivars capable of combining precocity, productivity and resistance to Cowpea aphid-borne mosaic virus (CABMV) is essential to passiculture. The aim of the current study is to evaluate vegetative and reproductive precocity, as well as resistance to CABMV, in a population of third generation backcross (BC3) involving an interspecific hybrid (P. edulis x P. cincinnata) followed by three backcrosses with com P. edulis. Eight hundred and thirty-three (833) progenies, 22 BC3 families and 10 yellow passion fruit (controls) accessions were evaluated. Phenological stages were assessed based on the number of days after planting (DAP) when progenies presented primary, secondary and tertiary branches, flowers and fruits in these branches. CABMV severity was analyzed under field conditions based on a rating scale that ranged from 1 (resistant) to 4 (highly susceptible); values were converted into McKinney's disease index (DI%). Overall, BC3 families were superior to control treatments (P. edulis accession), since they presented greater precocity, productivity and resistance to CABMV. Based on CABMV?s classification, 34 progenies were considered resistant (DI from 0.0 to 14.81%) and 299 were moderately resistant (DI from 16.67 to 30.0%). Findings in the current study have shown that BC3.A, BC3.B and BC3.G families have potential to be used in breeding programs, since they showed more precocious vegetative and reproductive vigor, accumulated production higher than 70 fruits per plant and resistance to CABMV.

the present study, we evaluated the influence of agroforestry systems and traditional agriculture on the physical attributes and biologicals of soil, using as reference a native forest area in Paraty, RJ. Levels of total soil organic carbon, as well as oxidizable fractions and aggregate stability, were analyzed, in addition to the activity and carbon and nitrogen content in the soil microbial biomass, in the 0?5 cm layer, in two distinct seasons (dry and rainy seasons). |
