1. TL1-Zimbabwe
• Objective (i) identify drought tolerant lines from DAB
and CBIB lines
• -three sets of trials
• i) 6 x 6 lattice (DAB lines) for yield and other agronomic
characters across two locations. Replicated trial and
subjected to terminal drought.
• ii) 183 DAB lines for drought tolerance at 1 location.
Single row trials, with 2 replicates
• Iii) 80 CBIB lines for drought tolerance at two locations.
Replicated trial, four rows, 3 replicates
• Testing locations (Harare Research Station, Gwebi VTC).

2. Tablet
We are in the 1st year of using the tablet
Advantages already seen;
-eliminates the process of transcribing data from
hard copies into machine
-its difficult to read some peoples’ handwriting
and the tablet eliminates this
-you can communicate (phone and internet)
whilst in the field

3. IB fieldbook
• Fieldbook has been in use for the last 10 years at our institute.
• Primary users were the maize breeding team (after adapting fieldbook from
CIMMYT)
• Local training (within Crop Breeding Institute) involving 8 research officers to
demonstrate features in IB fieldbook and its potential use was done on 20 March
2012.
• All the officers showed interest of using the IB fieldbook in the 2012/13 cropping
season
• The field book is a useful tool
• - no errors as in manual or excel randomization
• - print field labels and fieldbook hard copies
• -compatible with the Tablet
• - good tool for data storage
• - faster than old ways of making fieldbooks
• However, the is no software for data analysis (compared to the old field book from
CIMMYT).
