The vehement controversies
surrounding the commercialization of Bt brinjal have not deterred
scientists at the Mahyco Research Centre. They have actually
accelerated their efforts by focusing on a host of highly specialized
biotech research programmes

A visit to Maharashtra Hybrid Seeds Company’s
(commonly referred to as Mahyco) state-of-the-art R&D facility at
Dawalwadi near Jalna, Aurangabad, will make any individual realize that
the cornerstone of Mahyco’s success till date has been its strong,
diverse and progressive R&D programmes. Owing to its ongoing
emphasis on research, Mahyco has several innovations to its credit.
Worldwide, Mahyco was the first company to successfully commercialize
F1 hybrid cotton based on genetic and cytoplasmic male sterility
systems. Mahyco was also the first company in India to produce and
market hybrid sorghum, pearl millet and sunflower. Most importantly, it
brought in a revolution in the Indian-agri community by commercializing
India’s first Bt cotton (Bollgard I) and then a superior Bollgard II in
2006.
The facility, which is called Mahyco Research Centre, was established
in 1998 with the purpose of conducting cutting-edge biotechnology
research in a number of areas relevant to crop improvement and
productivity. Major research areas of Mahyco include crop
transformation, molecular virology, molecular microbiology, gene
discovery, molecular markers, entomology and diagnostics. To monitor
particular protein content in genetically modified (GM) crops, it
established DesiGen Diagnostics, which provides diagnostics solutions
for GM crop testing for research scientists, seed producers and
farmers. This division today manufactures two kinds of kits — Elisa
Kits for Cry1AC and Cry1Ab gene and Bt gene detection strips.

“The technologies and traits that we work
on cuts across all crops”
— Dr Usha Barwale Zehr, director-research at Mahyco
Spread across 110 acres, the Mahyco Research Centre has 160,000 square
feet of wet lab space and boasts of nine biotechnology labs. “We had
our first biotechnology lab based out of Bangalore in 1986, but later
realised that biotech research needs to be centralized. Hence, these
labs were shifted to Jalna because in biotech, the technologies and
traits that we work on cuts across all crops,” says Dr Usha Barwale
Zehr, director-research at Mahyco. The R&D team in this center
focuses on field crops like wheat, rice and cotton, vegetable crops
like okra, brinjal, cauliflower, tomato, cabbage, radish and potential
crops like soyabean, sugarcane and potato. The company is also working
upon a number of traits to improve crop productivity. “Presently we are
working on insect tolerance (sucking and chewing pest), herbicide
tolerance, salinity tolerance, drought resistant seeds, nitrogen use
efficiency and resistance against disease and virus,” says Dr Bharat
Char, head of biotechnology research at the Mahyco Research Centre.
Research activities have become highly specialized due to which the
company is in a continuous process of upgrading its labs with the
latest high-end technology not just to increase yield but also to
discover traits which can help a crop battle against insects and
diseases. “The cycle is such that insects and pests develop a
resistance to even Bt crops after a period of time. Hence, it is very
important that we upgrade our technologies in discovering new traits
and metholodologies for crop productivity,” informs Dr Zehr. The
company is in the process of making considerable investments into
molecular makers for their molecular and biotechnology experiments.
“High-end molecular makers help our scientists to diagnose genetic
traits in a plant(s) in a short span of time and this in a way greatly
reduces the time of bringing the product to the market,” adds Dr Zehr.
For DNA extraction, molecular breeding labs utilize robotic automation
systems, which can take in a large number of plant samples at one time
and at high thoroughput speed. While the molecular breeding labs
diagnose gene traits in a plant, the molecular biology lab is even more
specialized as it discovers particular traits in a plant against
insects like chewing and sucking pest and even traits like salt and
drought resistance. The plant transformation labs (wherein the gene is
transformed to the plant) looks into both vegetable and field crops.
The lab is developing a vast array of biotechnology approaches to
develop insect and disease resistant crops. These biotechnology methods
will be examined in rice, okra, tomato, brinjal, cauliflower and
cabbage. Scientists at the Mahyco Research Centre are also looking at
using GM technology to modify expression pattern of a plant’s own gene
with the aim that the plant/crop uses and absorbs a large amount of
nitrogen from the soil.
These highly specialized research programmes are the brainchild of a
group of highly qualified pool of scientists and technicians working at
this center. The management attributes that being a research driven
company, they are extremely particular about bringing on board highly
qualified scientists. “Most of our scientist have foreign PhDs with 3-5
years of post doctoral experience abroad. All our PhDs are mainly from
the US,” adds Dr Zehr.
Going forward, the industry will see a host of exciting programmes
coming out from this centre. Apart from expanding on its hybrid
business, the centre is gearing up for bring out the RR (Roundup Ready)
cotton, Bt brinjal and discovering new traits in crops. Looking at the
vast spectrum of research programmes, which the company is currently
engaged in, there will be an additional 30,000 square feet of
laboratory space added in the coming months.
