A NOTED Filipino agriculture scientist said the country’s
salvation from hunger comes in the form of the lowly seed.
In an article to be published later this month, Dr. Calixto
Protacio, a US-trained professor of agronomy at the University
of the Philippines Los Baños, argued, “Biotech
crops are the ultimate products of science-based agriculture.
The development of biotech crops harnessed almost every scientific
discipline from the crop sciences to genetics, biochemistry
and even computer science. It will be hard to conjure a more
visible product of the sciences in agriculture other than
the biotech crops.”
Protacio added that the biotech seed is a weapon that reaches
the farmer and does not need to be trained on improved technology
to benefit from the crops grown through genetic improvement.
It has been the bane of many countries, he added, that improved
technology seldom reaches the intended targets, and that
extension workers are not trained appropriately to impart
the new knowledge.
“Biotechnology’s potential is to bring science
to the countryside even without extension workers. How? Just
by giving the farmer [the] improved seed! If we can incorporate
into a seed all that science has to offer, then the fruits
of science [actually a seed] would have reached the farmer.
This scheme fits in the natural cycle of agriculture where
a farmer will secure the best seed he can get,” Protacio
stressed.
Besides the seeds, he added that the biotech product may
also be a tissue-cultured plantlet.
“But even if produced by tissue culture, especially
if by somatic embryogenesis, synthetic seeds can also be
produced by encapsulating the somatic embryo in a suitable
gel-like medium usually along with everything that the embryo
will need—just like a natural seed,” he explained.
“So far the promise of biotechnology has only been
realized commercially in corn, albeit partly at that. Bacillus
thuringiensis (Bt) corn’s built-in crop protection
capability has reduced the chemical-related expenses for
growing the crop and the farmers seem to find it cost effective.
The herbicide resistance also incorporated in corn is also
relevant to our aging farmers as less labor is required to
weed the extensive corn fields,” Protacio said.
While there has been enormous success in propagating Bt
corn in the country, commercial seeds developed by biotechnology
still have to make their mark in the rice farms and coconut
plantations, he lamented.
“The reason for this is that the private industry
invested heavily in corn-biotechnology research unlike in
the two other crops. Biotech research in rice and coconut
are primarily publicly funded. However, the fact that public
money is spent on these crops promises that the crop eventually
developed will be more relevant to the farmers and the general
population,” Protacio admitted.
The biotech expert bared that the government has been working
hard to develop Golden Rice, which have genes that carry
vitamin A, to enable more and more poor communities to benefit
from the nutrients.
Vitamin A is crucial in battling blindness.
Nonetheless, experts are still arguing over the practical
impact of Golden Rice since research has to be done to boost
the capability of the strain to harbor a bigger amount of
the nutrient.
