INIFAP since autumn .</p><p>winter season 1998/1999 in some different experimental</p><p>stations developed a seed production program, and</p><p>established 300 hectares. The results of this program were</p><p>530 tons of basic seed (500 t of seed of open pollinated</p><p>varieties and 30 t of parental seed of hybrids). Researches of</p><p>Seed Production obtained the complete information about</p><p>technology of seed production for each hybrid and parental</p><p>lines: best environment for seed production, detaseling,</p><p>flowering synchronization, fertilizer treatment. INIFAP</p><p>released twenty six varieties; and established a program of</p><p>seed production of the registered seed of the materials: H-</p><p>519C, H-553C, H-365C, H-363C, H-364C, H-367C, H-</p><p>441C, H-469C, H-551C, H-368C, HV-521C, V-537C, V-</p><p>538C.</p>}, number={2}, journal={Agronomía Mesoamericana}, author={Espinosa-Calderón, Alejandro and Gómez, Noel and Sierra, Mauro and Betanzos, Esteban and Caballero, Filiberto and Coutiño, Boulmaro and Palafox, Artemio and Rodríguez, Flavio and García, Abraham and Cano, Octavio}, year={2003}, month={Sep.}, pages={223–228} }
