New OPV
varieties released by Maize Team of INIA
by
Dr. Miloje Denic, Maize Breeder,
INIA
The varieties released are OPV of normal
maize, namely, Djandza, Chinaca, Tsangano, and Changalane. The first
three varieties, originated from regional SADLF project coordinated
by Marianne Banziger of CIMMYT, Harare.
Original drought/low N tolerant CIMMYT material was passed through
four cycles of FS recurrent
selection under randomized drought/low N conditions. Under these
conditions, selection was made for earliness and hard grain texture. Variety
Changalane was reselected from INIA germplasm with early,
semi-flint, resistance to maize streak virus and downy mildew
background, originated from IITA, Ibadan. New released varieties
demonstrated superiority over existing open pollinating varieties.
Preliminary seed multiplication of foundation seed was initiated.
This work is part of INIA
Rockefeller Foundation supported project on National Maize
Improvement Program. Part of the program related to this subject,
and was reported in RF organized meeting on Biotechnology, Breeding
and Seed Systems for African Crops, November 4-7, 2002, Entebbe, Uganda |
