Producción y tecnología de semillas mejoradas de maíz por el INIFAP en el escenario sin la PRONASE.

Abstract: Producción y tecnología de semillas mejoradas de maíz por el INIFAP en el escenario sin la PRONASE. El Instituto Nacional de Investigaciones Forestales Agrícolas y Pecuarias (INIFAP) de México, incluyendo las instituciones antecesoras, han liberado 221 híbridos y variedades mejoradas en 62 años de mejoramiento genético de maíz. Estos materiales fueron de adaptación específica a diferentes condiciones ambientales. En mayor proporción se trabajo con híbridos de cruza doble y variedades mejoradas de polinización … Show more

“…That is valid in commercial sowings for the purpose of obtaining grains or in hybrid seed production. In these cases, technical recommendations often only indicate the days to flowering of the parents and, if applicable, differential plantings between females and males based on the number of days [20,[37][38][39][40]. Phenological characterization of parents based on GDD allows defining with greater precision the optimal sowing date to achieve floral synchrony [16,41].…”

“…En México, los centros de mejoramiento público manifestaron la necesidad de desarrollar nuevos esquemas de abasto de semilla básica con las empresas, para que sus productos de mejoramiento se comercialicen con los agricultores (Espinosa et al, 2003;González et al, 2008). Las empresas semilleras, por su parte, plantearon la necesidad de acceder a un abastecimiento de germoplasma adecuado y oportuno que asegure una producción de semilla comercial viable (Luna et al, 2012;Castañeda et al, 2014).…”

“…Mexico is the center of origin and genetic diversity of maize (Matsuoka et al 2002). Here, maize remains an important staple crop with economic and cultural value (Espinosa et al 2003), covering 28% of the total agricultural area (SAGARPA 2017) and yielding on average 3.7 t/ha (FAOSTAT 2016). To meet the national demand, a third of maize consumed in Mexico, totaling over 14 million tons in 2015, comes from import (FIRA 2016).…”

“…Of the 7.5 million hectares of maize grown annually in Mexico (FAOSTAT 2016), approximately two-thirds are planted with open-pollinated landraces (Espinosa et al 2003), which are dynamic populations that are genetically diverse, locally adapted, and have distinct identities. Maize landraces have been selected and maintained via traditional farming systems that, on one hand, maintain the attributes deemed valuable by farmers, like ear and kernel characteristics (Louette and Smale 1998), but on the other hand allow for gene transfer from other landraces, improved maize varieties, or even teosinte (Castillo Gonzalez and Goodman 1995; Louette and Smale 1998; Baltazar et al 2005; Wang et al 2017).…”
