CZR3, CZR4, & CZR8, were released by
the Agricultural Technology Clearing Committee (ATCC), Malawi on
November 7, 2002. These hybrids were formed using combinations of
inbred lines that were identified to be good for various stresses by
REGNUR collaborators.
-
Ugandan releases: OPVs Longe 4 (LP 16)
and Longe 5 (Obantapa) in 2000; 3-way cross hybrids Longe 6H, Longe
7H and Longe 8H in November 2002.
-
Formation and/or testing of
hybrids using NARS lines and CIMMYT single crosses/OPVs/lines by
various NARS: Malawi, Zimbabwe, Zambia, Mozambique.
-
Work plans were formulated for a
collaborative effort where the NARS would develop disease resistant
and abiotic stress tolerant inbred lines using a combination of NARS
germplasm and CIMMYT germplasm (pedigree breeding). This approach
is especially important for broadening the germplasm base of the
NARS and to sustain their breeding program for a long time as it
would ensure a continual supply of new inbred lines. This effort is
already underway in the NARS of Zimbabwe and Mozambique and is about
to begin in the NARS of Kenya, Malawi and Zambia.

Visiting scientists in 2003: Two
Kenyan REGNUR collaborators visited the Zimbabwean National Program
and CIMMYT. They were introduced to both the programs and were also
trained to use the computer program "Fieldbook" which generates
pedigrees of newly formed combinations and enables efficient
management of nurseries, trials and seed inventory.
-
A two-day workshop (March 2003) was
held in INIA-Maputo to train 8 collaborators (scientists and
technicians) to use "Fieldbook".
-
Completed computerized inventorying of
INIA (Mozambique) germplasm and current season nurseries. A similar
effort is on-going with the NARS of Zimbabwe, Malawi, Muguga-Kenya,
Kakamega-Kenya.
-
A user's manual for the computer
program "Pedigree" was developed. This program is an extension of
and complements the nursery and trial management features of
"Fieldbook".

REGNUR has strengthened the existing
collaborative links with Coordinated Ecosystem Breeding (CEB) and
Southern Africa Drought and Low Fertility (SADLF) projects. New
germplasm is being developed/identified by the NARS using a system
of germplasm sharing, exchange and testing using the REGNUR-CEB
network. REGNUR links to SADLF comes by the way of mother-baby
trials where germplasm developed by REGNUR collaborators is being
tested on farmers' fields.
