	MU03-022 yields are high and stable in absence (above) or presence (below) of maize streak virus disease

During a recently convened National Performance Trial meeting in Nairobi, Kenya (November, 2006), ten (10) improved maize varieties bred by Kenya Agricultural Research Institute were recommended for pre-release or full release.

The varieties released include:-

Four Open Pollinated Varieties (OPVs) were recommended for release in the Dryland areas of Kenya (1200 masl)
Two High Yielding Maize Streak Virus resistant Hybrids were recommended for pre-release in the Mid -Altitude areas (1600-1800 masl) of Kenya
One Open Pollinated Variety (OPV) with stem borer resistance was released for the Mid- Altitude areas of Kenya (1600-1800 masl)
One Hybrid was pre-released for the High Altitude areas of Kenya (1800-2200 masl)
One Open Pollinated Variety (OPV) for frost prone areas of Kenya (>2400 masl)

The varieties produce higher yields than those currently grown by farmers, are tolerant to drought and also resistant to maize streak virus disease, stem borer damage, and turcicum leaf blight and gray leaf spot. The varieties are available for commercialization in dryland, mid-altitude and highland ecologies of Kenya. Read the full story at http://www.africancrops.net/news/dec06/ininda.htm.
