Development, maintenance and seed multiplication of open-pollinated maize varieties. 2 ed.
1999
The procedures for the production of maize hybrid seed and maintenance of parental lines are well documented. However, not much has been written on the development, maintenance, and multiplication of improved open pollinated maize varieties (OPVs). This bulletin provides appropriate, user-friendly procedures and guidelines for variety development, evaluation and variety release systems, characterizing open-pollinated varieties, maintenance and seed production (breeder's seed, foundation seed, certified seed), isolation standards for seed production, standards for maintaining varietal uniformity, as well as for keeping reserve stocks, choosing sites for seed multiplication fields, and determining necessary quantities of seed.
