Aluminum toxicity limits crop
production in Indonesia. At soil pH below 5, predominance of
Al3+ causes inhibition of root cell division and root
penetration ability thus decreasing plant productivity. Soybean,
an important crop in Indonesia is severely affected by aluminum
toxicity.
Development of soybean with tolerance to aluminum toxicity is
being studied at the Indonesian Center for Agricultural
Biotechnology and Genetic Resources Research and Development.
Using DNA markers (SSRs), tolerant lines selected from the F1s
of crosses between tolerant and sensitive plants were
identified.
Continued selection and breeding resulted in the development of
four F2 populations, where two selected populations demonstrated
high transgresiveness to three agronomically important traits.
This molecular breeding strategy is thus very useful for soybean
breeders and can be applied to other agronomic characters as
well.
