Runner cultivars are widely demanded by peanut farmers because of their high oil and grain productions. As those are late cycles, the management is limited in environments with water restriction.For improvement of runner genotypes to these environments is necessary to identify genotypes adapted and the knowledge of genetic divergence is quite relevant to assist the breeding procedures. In this work, ten morphological and agronomic traits were measured on 13 runner peanut genotypes grown in sandy loam textured soils during the rainy season in three environments on Brazilian Northeast region. These measurements included harvest index (%), main stem height (cm), 100 seed weight, 100 pod weight, pod length (mm), number of pod/plant, blooming (days after...

Efeito das mudanças climáticas sobre a favorabilidade climática à ocorrência da mancha preta do amendoim no Brasil e na Argentina. Repositório Alice
HAMADA, E.; GHINI, R.; RAGO, A. M.; BISONARD, E. M..
Abstract: Due to the intense relationship between environment and disease, changes in the geographical and temporal distribution of disease occurrence may occur as an impact of climate change. The responses of different pathosystems to climate change vary widely. This variation makes it necessary to study each response of the species or plant variety and its diseases in relation to climate change on a case-by-case basis.The objective of this study was evaluate the effect of climate change on the late leaf spot of peanut to Brazil and Argentina. Spatial and temporal distribution maps were obtained by GIS tool, applying criteria of mathematical logic of climate favorability to pathogen incidence, developed by experts, and using the projections of future...
