Abstract

Métodos para producir plantas, semillas y células vegetales haploides dobles de maíz (Zea mays). Reivindicacion 1: Un método para obtener una planta de maíz haploide duplicada que comprende: a) polinizar estilos de una mazorca de maíz con una línea inductora para producir al menos un embrion haploide; b) poner dicho embrion haploide en contacto con un agente de duplicacion de cromosomas para producir al menos una célula embrionaria haploide duplicada; c) generar una planta de maíz haploide duplicada a partir de dicha célula embrionaria haploide duplicada, y; d) en donde el paso (b) tiene lugar 4-21 días después del paso (a).
