The National Research Institute of
Forestry, Agriculture and Livestock (INIFAP) and CIMMYT
have been working in some researches to support and
promote the intensive commercial use of new Quality Protein
Maize (QPM) hybrids and varieties. INIFAP since autumn .
winter season 1998/1999 in some different experimental
stations developed a seed production program, and
established 300 hectares. The results of this program were
530 tons of basic seed (500 t of seed of open pollinated
varieties and 30 t of parental seed of hybrids). Researches of
Seed Production obtained the complete information about
technology of seed production for each hybrid and parental
lines: best environment for seed production, detaseling,
flowering synchronization, fertilizer treatment. INIFAP
released twenty six varieties; and established a program of
seed production of the registered seed of the materials: H-
519C, H-553C, H-365C, H-363C, H-364C, H-367C, H-
441C, H-469C, H-551C, H-368C, HV-521C, V-537C, V-
538C.
