Developing maize hybrids is a venture that requires …..
elite sources of germplasm (genetic variability)
skilled personnel (training)
an evaluation network (collaboration) and
resources
![Page 4: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/4.jpg)
To be ahead in the game, tap into …
the power of informatics (computing)
molecular marker technology
But these technologies further raise the threshold of skill and resources

CIMMYT’s Comparative Advantage/Success Formula ……….
The CIMMYT Genebank
Close to 25,000 maize and teosinte accessions
![Page 6: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/6.jpg)
CIMMYT’s Comparative Advantage/Success Formula ……….Deployment
Trainees Formal – 700 B Sc, M Sc and Ph D students
from 74 countries Informal – 10,000 researchers
Network National Agricultural Research Systems
(NARS), Advanced Research institutes (ARIs), Universities, Non-Governmental Organizations (NGOs), and private seed companies
![Page 7: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/7.jpg)
CIMMYT’s Comparative Advantage/Success Formula ……….
THE IMPACT Inbred lines, OPVs, hybrids, donor stocks
used world wide by both public and private partners
Maize varieties developed by CIMMYT and its partners cover half the area sown to improved varieties in non-temperate areas of the developing world

Proposed Sub-Projects
Sub-Project 1: Germplasm development and distribution
Sub-Project 2: Training
Sub-Project 3: Evaluation of Hybrids
![Page 10: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/10.jpg)
Sub Project 1: Development and distribution of inbred lines
Activity 1.1: Development & distribution of early generation pedigree bulks
Identify 3 high priority target environments and traits by a majority vote
CIMMYT identifies elite donor & recipient lines from its germplasm base
CIMMYT forms F1 derived F2 pops or multi-parent breeding synthetics for line extraction
F2, F3 or F4 bulks will be made available to collaborators
Collaborators extract own proprietary lines
![Page 11: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/11.jpg)
Sub Project 1: Development and distribution of inbred lines
Activity 1.2: Development and distribution of advanced generation lines untested for combining ability but tested per se for specified target traits
F5, F6 or F7 inbred bulks from Activity 1.1 will be evaluated per se for target stresses. Advanced generations will be made available
Collaborators directly use these lines in combination with their own lines to generate proprietary hybrids
CIMMYT obtains feed-back from collaborators on line performance (per se and hybrid) for recycling into new pedigree breeding projects
![Page 12: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/12.jpg)
Sub Project 1: Development and distribution of inbred lines Tapping into a broad germplasm base
Lines for target traits in target environments
Breeding populations will be non-heterotic
Selfing in heterotic sources has less probability of success
=> more effort and resources to identify good lines
![Page 13: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/13.jpg)
Sub-Project 2: Training Lessons Learnt
CIMMYT gives germplasm
What to do with it?
How to do it?
Who (lack of trained personnel)?
Resources (too expensive to do breeding)?
![Page 14: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/14.jpg)

Sub-Project 2: TrainingActivity 2.1 Management of Maize Breeding ProgramsThe Approach Interested company grows a pre-determined
number of rows (e.g. 500 rows) of segregating (F2/F3) bulks/families
“company comfortable” % of proprietary germplasm (e.g. 50% proprietary, 50% CIMMYT).
Nursery is grown at a CIMMYT location (e.g. Hyderabad) for one season
Each participant’s nurseries are clearly marked and identified
CIMMYT coordinates/organizes all field operations
![Page 17: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/17.jpg)
Sub-Project 2: TrainingActivity 2.1 Management of Maize Breeding ProgramsThe Approach
Trainee supervises all crop operations (planting, pollination, selection, harvest, shelling, and data analysis) and makes selections while under constant technical supervision from CIMMYT
Selected advances remain the property of the concerned seed company and gets shipped back in its entirety to the company
Selection for the target environment - with duplicate evaluation nursery (single row, no pollination) at own target site.
![Page 18: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/18.jpg)
Sub-Project 2: TrainingActivity 2.1 Management of Maize Breeding ProgramsAdvantages Customized training given to the breeder keeping in
mind the needs of the company
The breeding objective is relevant to the trainee/company
Accountability: At the end of a season a tangible output (seed of advanced generation) is generated for the company
neither extra time nor money is spent on separate training or for a breeding advance
A breeding advance is generated under CIMMYT supervision while the trainee is being trained.
![Page 19: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/19.jpg)
Sub-Project 2: TrainingActivity 2.1 Management of Maize Breeding ProgramsAdvantages
The breeding material remains proprietary
Especially suited to trainees from companies that are
small to medium in nature
wish to grow in the maize seed business through having their own portfolio of hybrid products
![Page 20: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/20.jpg)
Sub-Project 2: TrainingActivity 2.2 Data Management
Genetic gain is a function of (NO, not a text book definition)
Selection intensity
Resource efficiency
=> make informed decisions: to do that, data turnaround is critical to breeding operations, especially that of maize
The elements of quick data turn around:
Fast data capture
Quick data analysis
Availability of visualization tools to finalize selection
![Page 21: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/21.jpg)
Sub-Project 2: Training-Data ManagementCIMMYT is able to offer ….
Fieldbook-IMIS System Developed at CIMMYT Developed by maize breeders for maize
breeders Tailored to maize Excel based interface
Very flexible Power of Excel at user’s disposal
Back end database - International Maize Information System (IMIS)
Powerful in pedigree management
![Page 22: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/22.jpg)
Sub-Project 2: TrainingActivity 2.2 Data Management
CIMMYT Data Manager spends 2 weeks with each seed company implementing Fieldbook-IMIS
Needs to be a fully funded position
![Page 23: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/23.jpg)
Sub-Project 3: Hybrid TestingWhy the need? Unlike wheat, maize has genotype x
environment interaction
=> a hybrid good at a location need not be good at another location
Breeding for identified target environments is crucial to derive maximum return to investment
Climate change is real: erratic rainfall, global increase in temperature
Test more environments and more years as there is variation within a mega-environment and between years
![Page 24: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/24.jpg)
Sub-Project 3: Hybrid TestingWhy the need?
Seed company needs performance data to enter the market in another country
Such testing demands careful planning, logistics and resources
Testing at All-India level is being done by DMR
Proposal: Asia-Regional Hybrid Testing
![Page 25: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/25.jpg)
Sub-Project 3: Hybrid TestingApproach
Types of trials
early to intermediate maturing hybrids
intermediate to late maturing hybrids
Each seed company submits hybrids
Size of each trial would be determined based on the demands
Each trial would be grown in 3 replications, 2 rows per plot
![Page 26: Hybrid Maize Research Consortium B. S. Vivek Awareness Meeting 19 March 2010.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649de55503460f94add197/html5/thumbnails/26.jpg)
Sub-Project 3: Hybrid Testing Multi-location regional testing:
The number of sites and the locations would be determined based on the priorities expressed
Trial Coordination: done by CIMMYT @*
@ Assumptions : the coordinator at CIMMYT will be fully funded by member companies;
* Risks for Sub-Project 3: for regional testing: import of seed for forming the trials and dispatch of trials (export) outside India requires tremendous logistical planning and effort due to existing import, export procedures.
