Definition
Plant breeding, or crop genetic improvement, has great potential
for improving food security, nutrition, and poverty reduction
for poor farmers. Plant breeding played an important role
in the "Green Revolution," which has been credited
with improving global food security. Until fairly recently,
most plant breeding programs have focused on developing input-responsive
varieties that performed well under optimum growing conditions.
The bulk of investment in plant breeding was focused on a
relatively few crops, such as wheat, maize and rice. The millions
of poor people who live in marginal environments are disadvantaged
by this bias. It is now becoming more widely appreciated that
new approaches are required to help breeders develop higher
yielding, varieties for severely-resource constrained farmers
who live in environments where significant abiotic (poor soil
fertility, drought, high temperatures, etc.) and biotic (pests
and diseases) constraints are the norm.
Examples of specific objectives in plant breeding related
to and of relevance to the CCRP include:
- Improving the productivity of under-researched crops such
as tef, finger millet, and quinoa;
- Improving the adaptation of crops to nutrient-limited
soils, such as soybean on P-deficient soils in S. China
and S. Africa;
- Improving the resistance of crops to diseases and pests,
such as insect pests; affecting sweetpotato and chickpea;
diseases affecting rice and finger millet;
- Improving the nutritional value of sweetpotato and sorghum.
This page is aimed at providing resources on approaches that
can help researchers achieve objectives such as the above.
Specifically, the resources listed here relate to plant breeding
in general and to several sub-topics of potential interest
to multiple CCRP project teams and others working in related
areas.

Plant Breeding News (PBN)
- Website: FAO
- Description: "The overall objective of PBN is to
stimulate wide discussion and share news and information
on plant breeding and related topics, including new results,
methods, concepts, inquiries, announcements, etc. PBN is
not for publishing research papers of the type submitted
to a refereed journal. It is foreseen that there will be
one edition of the PBN each month but if there are many
contributions, another issue may be released to avoid excessively
long issues. News Flashes containing very time-sensitive
topics or inquiries may also be sent from time to time.
Special issues focusing on one major topic may also be considered
in the future."
Plant breeding abstracts
- Website: CABI
publishing
- Description: "Plant Breeding Abstracts is a fully
searchable abstracts database of internationally published
research. Plant Breeding Abstracts brings you the latest
information on plant breeding, genetics and biotechnology,
from wild relatives to new cultivars, from protoplast isolation
to transgenic plants, from gene expression to inheritance."
