Genetic diversity of arboreal cotton populations of the Brazilian semiarid: a remnant primary gene pool for cotton cultivars

Mocó cotton belong to the same species as the cultivated species, Gossypium hirsutum, and cultivated forms were mainly landraces but also developed as cultivars, bearing good fiber quality and drought tolerant when cropped as a perennial species. The northeast Brazil crop system based on this cotton type is finished, with a few small area planted in the three.. Read More»

Adaptability and stability of genotypes of sweet sorghum by GGEBiplot and Toler methods

    U.J. de Figueiredo, J.A.R. Nunes, R.A. da C. Parrella, E.D. Souza, A.R. da Silva, B.M. Emygdio, J.R.A. Machado and F.D. Tardin

Sweet sorghum has considerable potential for ethanol and energy production. The crop is adaptable and can be grown under a wide range of cultivation conditions in marginal areas; however, studies of phenotypic stability are lacking under tropical conditions. Various methods can be used to assess the stability of the crop. Some of these methods generate the same basic information, whereas others.. Read More»

Biotools: an R function to predict spatial gene diversity via an individual-based approach

    A.R. da Silva, G. Malafaia and I.P.P. Menezes

The gene diversity or expected heterozygosity (HE) is based on the allele frequency and is often used as a measure of genetic variability of populations. Knowing the pattern of spatial distribution of HE can be useful for determining strategies of conservation and sampling of collections of individuals. In addition, it can allow one to detect genetic boundaries in a.. Read More»
