“…Diante disso, o controle de pragas no cultivo de milho é fator preponderante para garantir sua qualidade e valor de mercado, o que tem alavancado novas tecnologias, como a transgenia, criando variedades tolerantes a herbicidas ou resistentes a insetos (COLLI, 2011). Visando ao aumento da sustentabilidade no meio rural, muitos produtores já usufruem dos benefícios do milho transgênico, buscando maximizar a produtividade das lavouras, reduzir custos de produção e diminuir a aplicação de agrotóxicos (QAIM & MATUSCHKE, 2005).…”

RESUMO O objetivo deste trabalho foi verificar a divergência genética entre genótipos de milho transgênico, em relação à produtividade de grãos e à qualidade nutricional. O experimento foi conduzido na safra 2009/2010, em Santa Maria, Estado do Rio Grande do Sul, no delineamento blocos casualizados, com três repetições. Foram avaliados 18 genótipos e mensuradasas seguintes variáveis após a colheita: produtividade de grãos, proteína bruta, lisina, metionina, cisteina, treonina, triptofano, valina, isoleucina, leucina, fenilalanina, histidina, arginina, extrato etéreo, amido

“…Accumulating evidence indicates that the current GM crops can clearly prove beneficial to small as well as large farmers. Varieties of cotton with the toxin gene from Bacillus thuringiensis (Bt) are proving their worth to poor farmers in South Africa (21) as well as parts of Asia (22,23), and Bt rice is performing well in late-stage trials in China (24). The benefits of these crops can be quite different depending upon circumstances.…”

Enhancing agricultural productivity in those areas of the world bypassed by the Green Revolution will require new approaches that provide incentives and funding mechanisms that promote the translation of new innovations in plant science into concrete benefits for poor farmers. Through better dialogue, plant breeders and laboratory scientists from both the public and private-sectors need to find solutions for the key constraints to crop production, many of which center around abiotic and biotic stresses. The revolution in plant genomics has opened up new perspectives and opportunities for plant breeders who can now apply molecular markers to assess and enhance diversity in their germplasm collections, to introgress valuable traits from new sources, and to identify genes that control key traits. Functional genomics is also providing another powerful route to the identification of such genes. The ability to introgress beneficial genes under the control of specific promoters through transgenic approaches is yet one more stepping stone in the path to targeted approaches to crop improvement, and the new sciences have identified a vast array of genes that have exciting potential for crop improvement. For a few crops with viable markets, such as maize and cotton, some of the traits developed by the private sector are already showing benefits for farmers of the developing world, but the public sector will need to develop new skills and overcome a number of hurdles to carry out similar efforts for other crops and traits useful to very poor farmers.crop genomics

“…Many studies have pointed out that the non-food GM crops are either none or least controversial e.g. cotton is being grown in Pakistan on large area (Ali and Abdulai, 2010;Crost et al, 2007;Qaim and Zilberman, 2003). Therefore, the current research is among the few studies focusing on the consumers' acceptance of the GM foods in Pakistan.…”

ABSTRACT. In Pakistan majority of the consumers do not have information about genetically modified (GM) foods. In developing countries particularly in Pakistan few studies have focused on consumers' acceptability about GM foods. Using comprehensive primary dataset collected from 320 consumers in 2013 from Pakistan, this study analyzes the determinants of consumers' acceptability of GM foods. The data was analyzed by employing the bivariate probit model and censored least absolute deviation (CLAD) models. The empirical results indicated that urban consumers are more aware of GM foods compared to rural consumers. The acceptance of GM foods was more among females' consumers as compared to male consumers. In addition, the older consumers were more willing to accept GM food compared to young consumers. The acceptability of GM foods was also higher among wealthier households. Low price is the key factor leading to the acceptability of GM foods. The acceptability of the GM foods also reduces the risks among Pakistani consumers.
