Could it be because these crops are the most important food crops in your country? Because it is the same trend in countries where wheat and rice are the main staple crops. Green revolution focused on the most important food crops.

That's a very good question. The crops like rice , wheat and maize witnessed a quantum jump in increased productivity due to new varieties coupled with their extreme responsiveness to chemical fertilizers. Unfortunately , other traditional crops or crops rasied with trditional practices failed to witness same magnitude of yield response. That's the prime reason , we often ask these days, whether our traditional varieties are capable of witnessing such yield responses, when we get them into organic agriculture, this doubt becomes much stronger. Do we

need different varieties to be fitted In organic and inorganic fertilization ..??

@Rajashekhar There has been substantial impact of green revolution worldwide especially on food and nutritional security, cropping pattern, and environment. Although the sum total of impacts has been positive, but negative impacts have also fetched the attention of researchers the world over. For details, one can go through the feature article published in the Trends of Plant Science (Vol: 21: 31-42):

https://doi.org/10.1016/j.tplants.2015.10.012

The traditional crops are withdrawn from the cultural practices after the success in green revolution as they are of less productivity as compared to the HYV. But the traditional varieties are being used in the breeding program to add important trait to the HYVs.

Rice, wheat and maize are the main staple crops in your country. Green revolution especially focused on the most important food crops to fulfill consumer demand in a area.

The green revolution in India focused more on the high yielding crops and which are pest resistant so as to cater the need of growing population.. The high yielding varieties of the crops like wheat, rice , maize , sorghum have been much more experimented & developed healthy as earlier.However, the use of more Chemical fertilizers and crop protection agents have been made as compared to the traditional crops prone to attack by pests and diseases.The agri-production of the traditional crops has been suppressed.

on traditional crops of India

Green revolution destroy our majority of traditional crops...

In our region (Panchmahal and Dahod distric of Gujarat)15 year ago we have a sweet and small size seeds of maize, it called (local maize) but after comes hybrid seed of maize, it can dominant over 99% in total agricultural region, now we don't have any seeds of our local maize.

Conclusion is that if we introduce some hybrid verity in our region so first conserve our own species, otherwise it extinct.

Hello Dr. Kamlesh Gadhvi ,

Your views are true. In my country, many of our traditional crop varieties have disappeared because they have been replaced by modern varieties.

This is because of the following reasons.

1. These crops are selected due to their prolific nature.

2. Due to their capacity to adapt to a wide range of environments.

3. Their yield response is very high to chemical fertilizer as compared to other crops.

4. These crops are selected due to their ease of breeding nature which is important to generate hybrids.

No doubt that the green revolution brought the self-sufficiency in major food crops throughout the entire world. But in the same way, the introduction and cultivation of high yielding varieties or modern cultivars commercially on large scale result in the elimination of our traditional varieties which were the store of valuable genes governing adaptability, resistance, and some important quality characteristics. By losing traditional varieties due to the green revolution we have lost a valuable treasure of so many important traits. Nowadays efforts are being made in the protection of various traditional varieties of specific crops because even today we can use traditional varieties as a source parent in the incorporation of the valuable gene which they possess into the present-day cultivated crops which lack such valuable traits. Therefore, being an important source of valuable genes, under the aegis of CGIAR and its associated Research Institutions, special priority is given in the conservation and preservation of all the traditional varieties of specific crops.

Traditional cereals crops are there and good work has been done in India on minor cereals, Karnatka scientist has done good work. One can find a lot of literature on old issues of the Indian Journal of Genetics and Plant Breeding. Of late ethnogenomics work is going by Tamil Nadu scientists in collaboration with US scientists.

Main objective of green revolution was feeding lorge population so monocroping, higher productivity. People are so adopted for green revolution reccomendation that all treditional systems were ignored but recently they are getting much importance

Millers should be given due importance by agriculture dept and breeders. They are now commonly used by many food and health conscious people. Now a days there a more demand multifarious food and people are liking it.! The Govt should encourage research and researchers in this area for sustainable and healthy food habit

Prior to the Green revolution in India, several indigenous varieties of crops were grown, but the advent of Green revolution has led to cultivation of some high yielding varieties of crops only. This has not only resulted in uniformity in biological diversity, but also has led to the loss of biological diversity. The local indigenous varieties lost their importance due to the persistent use of high yielding varieties. The loss of land races and indigenous varieties is a matter of serious concern as these crop varieties possess several useful characters (resistance to diseases, pests, drought etc.), that can be used in the crop improvement programmes.

Many thanks for sharing your knowledge

Dear Rajashekhar Mandla

In post green revolution era, productivity of all the major crops have increased in India. In order of productivity gain in the year 2017-18 over the year 1966-67 (preceding year of green revolution) of major crops are as follows:

Wheat (280%)> Bajra (238%)> Maize (214%)> Rice (198%)> Oilseeds (197%)>Pulses (123%)> Jowar (95%)

Many factors such as nature of crops, the proportion of major macro-molecules contained in the seed, etc including policy decisions could account for such a difference in the productivity gain.

Thank you,

Arbind

Because paddy and wheat have been the main staple food of India as well as South Asia for a long. From 1960 to 1970, there was a shortage of food due to drought in the region. The Green Revolution since around 1965 made India self-sufficient in food. Especially in wheat. It avoided starvation. Punjab and Haryana succeeded in this initiation mostly. I remember that people from our village started going to Punjab for work around the 90s.

After green revolution, the high yielding varieties were promoted and was focused on high management practices. Therefore, the traditional crops were discraged.

I agreed with Bir Bahadur and Anoop Kumar Srivastava

There is a need for genomics and ethnogenomics studies of minor cereals for their improvement

Of late , application of some biotechnological tools like RNAis and CRISPER have come under some scathing remarks for with end product similar to genetically modified crops ,which have their own stigma in many social circles in many of the most advanced countries. Any remark on this issue....

The crops are the same but its only genetic improvements in varietal evaluations and biotehnological advancements. The same is the case with practices and technologies. Old practices in new, modern and catchy names. For e.g. Agriculture has been practised based on climate only for time immemorial. But now a new name climate smart agriculture'. Changing with times is required.

As diversification is our existence everywhere without which life wont be possible but due to green revolution we sacrifice our own local resistant verities from independency on other to dependency on chemical fertilizer hybrids seeds and many more things we have our own self sustaining chain but due to mono culture although it has great contribution in saving millions life but when we see from naturalistic point of view some major crops has dominated over so many minor traditional crops

We have 50 species of Dioscorea whose tubers are edible there is little or no work. This is equally very important crop. Worldwide there about 800 species. INDIAN ARE LAGGING BEHIND.

Green revolution in India has helped in the cultivation and popularization of other non-conventional cereal crops like millets across the Indian landscape.
