Problems in the seed production, distribution and use of OPVs [open-pollinated corn varieties] varied in nature, frequency, and degree across locations. Fifteen problems were identified by seed producers, the most serious of which were high production cost, lack of storage facilities, and control of weeds and insect pests. The seed distributors perceived fourteen problems, the most serious being low demand for seeds, risk of unsold seeds and lack of storage facilities. Similarly the farmer-users identified seven problems in seed usage among them were irregular seed availability, lack of seeds in remote areas and bad farm-to-market roads. The channels in the production and distribution of OPV seeds were the various offices and units of the Department of Agriculture, state universities and colleges, private seed growers and dealers and farmers. Among the five OPVs, IPB Var 1 was most widely utilized, closely followed by IPB Var 2, then USM Var 2. IES Cn 1 and ViSCA 8341 which were just recently released were not yet commercially grown in the study sites. The estimated seed use for OPVs on the farmers level was only 1.73% compared with that of the hybrid which is 8.5% of the total area planted to corn.
