Contributions of plant breeding in Brazil: progress and perspectives

“…The first two were wheat and sugar cane, already in 1534. It should be emphasized that nearly all the plants currently grown in Brazil are from introductions made in the past (Nass et al 2012).…”

Assessment of the genetic variation in alfalfa genotypes using SRAP markers for breeding purposes

“…Unfortunately, this massive and uncontrolled introduction of modern cultivars has increased the erosion of genetic diversity, a gradual loss of performance by traditional populations, as well as their slow extinction (Benabderrahim et al, 2015). In the context of not losing the performance of the local germplasm, the main goals in many crops were the evaluation of their genetic diversity followed by the selection and introduction into local breeding programs (Nass et al, 2012). In the last few decades, a diverse range of local germplasm has been collected in Tunisia ; several projects for the development of new synthetic, high-yielding drought-and salt-tolerant alfalfa cultivars have been launched Benabderrahim et al, 2015).…”

Genetic diversity in populations of Maytenus dasyclada (Celastraceae) in forest reserves and unprotected Araucaria forest remnants

“…Extinction of these species even at a local scale results in loss of important genetic information and, consequently, reduced capacity for ecosystem recuperation. Knowledge of the genetic structure and diversity of plants is fundamental for their conservation and permits their use by local communities (Nass et al 2012;Asma et al 2016). In these sense, investigations of genetics in native plants with ecological and economical potential can inform both extractive activities and effi cient forest management (Piotti et al 2013).…”
