The Tomato crisis and how innovative seed technologies can comprehensively tackle it.
By: Raghavan Sampathkumar, Executive Director FSII.
India’s tomato market continues to remain volatile due to extreme weather conditions such as drought and deluge. This has led to unprecedented price volatility, with tomato prices surging over 300% in certain regions and costing around Rs. 200/kg.
India, ranking second in the world, produces over 20 million tonnes (in 2022) of tomato grown on 8.4 lakh hectares. Since several decades, the Indian government is undertaking several initiatives such as promoting use of high-yielding varieties and hybrids, modern agricultural practices like protected cultivation and micro irrigation, investing in irrigation infrastructure, encouraging post-harvest management and value addition. By focusing on research and development, tomato crop productivity can be improved significantly. Without sustained investments in R&D on cutting-edge technology-aided plant breeding, similar crises can occur in any crops anytime.
New breeding technologies (NBTs), with their remarkable capabilities, offer a ray of hope. For example, CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats), a promising gene-editing tool, holds immense potential to enhance agronomical traits like pest & disease resistance, extend shelf life, and boost productivity, stabilize prices and enhance fruit quality and emerged as a game-changer in tomato breeding, as highlighted in a study by Wang, T., Zhang, H. & Zhu, H. (2019).
I. Enhancing resistance against biotic stresses and tolerance against abiotic factors – CRISPR’s prowess lies in bolstering pest and disease resistance in tomatoes. By precisely targeting specific genes, researchers have successfully engineered tomatoes with heightened immunity against pathogens. This breakthrough trait ensures a consistent tomato supply, even amidst challenging weather conditions, which plays a vital role in stabilizing prices in the market. With disease-resistant tomatoes, farmers can mitigate crop losses, protect their livelihoods, and provide a stable tomato supply to the markets.
It is paramount to develop climate-resilient tomato varieties and hybrids. Though heat tolerance may not be a current priority for the tomato breeders, rising temperatures due to climate change will soon warrant this trait to be prioritized.
II. Prolonging shelf life – Utility of CRISPR technology goes beyond disease resistance, extending to the realm of shelf-life extension. Through precise gene editing, CRISPR has produced tomatoes with prolonged shelf life, effectively reducing post-harvest losses. Reduced spoilage and waste during storage and transportation contribute significantly to stabilizing prices in the tomato market. This translates to a steady supply of fresh tomatoes, and alleviating pressure on prices.
III. Boosting yield potential – CRISPR’s potential as a boon for farmers is further evident in its ability to enhance tomato yield. By optimizing genes associated with yield, fruit quantity and crop growth, researchers have developed tomato strains with improved productivity. Increased availability helps meet consumer demand, preventing sudden price spikes triggered by supply shortages and creates a win-win situation for farmers and consumers, fostering a more stable market.
Despite the immense potential of advanced technologies, their widespread implementation in India faces several challenges mainly, public perception. Through creating greater awareness about the scientific rationale, safety, and advantages of innovative technologies like gene editing, stakeholders can gain confidence on their positive and multidimensional socioeconomic impacts.
NITI Aayog estimates that the aggregate demand for fruits and vegetables demand will exceed 420 million tonnes in the next 10 years. But India continues to lose nearly 40% of its horticultural production worth billions every year.
Incentivizing investment in R&D is vital to drive development of superior varieties with improved agronomical and nutritional attributes. Along with conducive and evidence-based policy and regulatory frameworks, these innovative approaches can pave the way for a more stable, less volatile, climate-resilient tomato sector.

I was wondering if you ever considered changing the layout of your blog? Its very well written; I love what youve got to say. But maybe you could a little more in the way of content so people could connect with it better. Youve got an awful lot of text for only having 1 or 2 images. Maybe you could space it out better?

Its excellent as your other content : D, appreciate it for posting. “The real hero is always a hero by mistake he dreams of being an honest coward like everybody else.” by Umberto Eco.
We’re a group of volunteers and starting a new scheme in our community. Your web site provided us with useful info to work on. You have performed an impressive process and our whole community will likely be thankful to you.
The subsequent time I read a blog, I hope that it doesnt disappoint me as much as this one. I imply, I do know it was my choice to read, however I actually thought youd have something fascinating to say. All I hear is a bunch of whining about something that you can repair if you happen to werent too busy on the lookout for attention.
What’s Going down i am new to this, I stumbled upon this I’ve found It positively helpful and it has aided me out loads. I’m hoping to contribute & aid other users like its helped me. Good job.
Hmm is anyone else having problems with the images on this blog loading? I’m trying to find out if its a problem on my end or if it’s the blog. Any suggestions would be greatly appreciated.
As a Newbie, I am constantly searching online for articles that can be of assistance to me. Thank you
