Eficiencia de selección indirecta en maíz para ambiente futuro por cambio climático

Abstract: En la Mesa Central Mexicana se siembran en marzo y abril, más de 800 mil ha de maíz con humedad residual  y más de 650 mil bajo secano en junio. Se puede esperar que por cambio climático desaparecerá la humedad residual y toda la superficie tendrá que ser sembrada bajo secano. Existen muchos trabajos de mejoramiento genético de maíz en humedad residual, y nos podemos preguntar si será útil el avance por selección actualmente alcanzado al verse forzados a retrasar la fecha de siembra. Se evaluaron 40 familias d… Show more

“…Plant height (ALTP, m); value obtained at the end of the female flowering; measured from the base of the stem in the ground up to where the spike ramification begins. Stem diameter (DT, cm), ear height (AM, cm), length of the ear leaf (LHDM), width of the ear leaf (AHDM), total of leaves (TH) (Ramírez-Mandujano et al, 2016). The leaf area index per plant (IAF) was estimated using the average product of length times width for each leaf in five plants, weighed by a factor 0.75 (area of the leaves of the plant, m 2 ); then divided by the plant cover area above the soil (Castellanos-Reyes et al, 2017).…”
