Genotyping‐by‐sequencing approach indicates geographic distance as the main factor affecting genetic structure and gene flow in Brazilian populations of Grapholita molesta (Lepidoptera, Tortricidae)

Evolutionary Applications, Volume 8, Issue 5, Page 476-485, June 2015., 2015
Abstract The oriental fruit moth Grapholita molesta is one of the major pests of stone and pome fruit species in Brazil. Here, we applied 1226 SNPs obtained by genotyping‐by‐sequencing to test whether host species associations or other factors such as geographic distance structured populations of this pest. Populations from the main areas of occurrence

Selection Index in the Study of Adaptability and Stability in Maize

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
This paper proposes an alternative method for evaluating the stability and adaptability of maize hybrids using a genotype‐ideotype distance index (GIDI) for selection. Data from seven variables were used, obtained through evaluation of 25 maize hybrids at six sites in southern Brazil.

Cross Species Amplification of Pennisetum glaucum Microsatellite Markers in Pennisetum purpureum and Genetic Diversity of Napier Grass Accessions

Crop Science, Volume 52, Issue 4, Page 1776-1785, July 2012., 2012
ABSTRACT Napier grass (Pennisetum purpureum Schum.) is an important forage crop in tropical areas although little is known about its genome information, and few molecular markers have been developed for this species. This work aimed to check the viability of cross‐species amplification of microsatellite markers between pearl millet (Pennisetum glaucum)

Exotic, traditional and hybrid landscapes: The subtle history of the Iberian Peninsula maize between ‘tradition’ and ‘modernity’

PLANTS, PEOPLE, PLANET, Volume 6, Issue 5, Page 1047-1059, September 2024.
Maize is the world's second most important agricultural crop. The cereal was unknown to Europeans before the end of the 15th century, but since its arrival in Europe, it has changed agriculture, food and landscapes. Terraces where maize was cultivated in the Northwest of the Iberian Peninsula contributed to the formation of local cultures and ...

Resistance of Tomato Subsamples to Bemisia tabaci Biotype B (Genn.) (Hemiptera: Aleyrodidae)

Agronomy Journal, Volume 103, Issue 6, Page 1849-1861, November 2011., 2011
Whitefly (Bemisia tabaci) causes damage to tomato (Solanum lycopersicum L.) and is controlled by insecticides harmful to man and the environment. Development of resistant cultivars is ideal for whitefly management, with alternate genetic sources being indispensable. Germplasm banks are potentially good sources of resistant cultivars.
