      La dureza endospermática de granos de maíz depende de la concentración proteica, pero la composición del almidón podría afectarla también. Se ha reportado que endospermas con alta proporción de amilosa relativa al almidón ...
    • Environment, management, and genetic contributions to maize kernel hardness and grain yield 

      Cerrudo, Aní­bal Alejandro; Martinez, Dionisio Roberto; Izquierdo, Natalia Gabriela; Cirilo, Alfredo Gabriel; Laserna, Paula; Reinoso, Lucio; Valentinuz, Oscar Rodolfo; Balbi, Celsa; Andrade, Fernando Hector (2017-09)
      Dry milling performance of maize (Zea mays L.) is directly related to kernel hardness. This study assessed the contribution of maize hybrid and crop growing condition on kernel hardness and grain yield. Three hybrids that ...
