FAQs on Plant Breeding for Improved Food Video Lecture - NEET
| 1. What is plant breeding for improved food? |  |
Ans. Plant breeding for improved food refers to the process of selecting and crossing plants with desirable traits to develop new varieties that have enhanced characteristics related to yield, nutritional content, disease resistance, and other important attributes. This breeding approach aims to improve the overall quality and productivity of crops for better food production.
| 2. How does plant breeding contribute to improved food production? | |
Ans. Plant breeding plays a crucial role in improving food production by developing crop varieties with enhanced traits. By selecting and crossing plants with desirable characteristics, such as high yield, disease resistance, improved nutritional content, and better adaptation to environmental conditions, plant breeders can develop new varieties that contribute to increased food production and quality.
| 3. What are the key benefits of plant breeding for improved food? | |
Ans. Plant breeding for improved food offers several key benefits. It can help increase crop yield and productivity, ensuring a sufficient food supply for the growing population. Additionally, plant breeding can enhance the nutritional content of crops, making them more nutritious and addressing specific dietary needs. It also helps in developing crop varieties with increased resistance to pests, diseases, and environmental stresses, thereby reducing crop losses and minimizing the need for chemical inputs.
| 4. How long does it take to develop a new crop variety through plant breeding? | |
Ans. The time required to develop a new crop variety through plant breeding can vary depending on various factors. It typically takes several years of continuous selection and crossing to develop a new variety. The process involves multiple generations of plants, field evaluations, and rigorous testing for desired traits. On average, it may take around 8 to 12 years or even longer to release a new crop variety to farmers.
| 5. What are the challenges faced in plant breeding for improved food? | |
Ans. Plant breeding for improved food faces several challenges. Some of the key challenges include limited genetic diversity, as breeding programs often rely on a narrow range of genetic resources. This can hinder the development of new varieties with improved traits. Additionally, breeding for multiple traits simultaneously can be complex and time-consuming. Climate change and evolving pest and disease pressures pose additional challenges, requiring breeders to develop varieties that are resilient and adaptable to changing conditions.

plant breeding for improved food quality
even though there has been a tremendous
increase in the world food grain produce
still a large section of population is
lacking proper nutrition and quality
food out of seven billion more than 840
million people in the world do not have
sufficient food to meet their daily
nutritional requirements apart from that
it is estimated that about three billion
people suffer from a condition called
hidden hunger hidden hunger is when
people are able to fill their stomach
and they don't feel hungry anymore but
the food they ate had lot of calories
but lacked in essential micronutrients
required for the development of the body
hidden hunger happens when people
consume more amount of staple foods like
rice wheat jobber etc and completely
neglect foods like fruits legume
vegetables meat fish etc that are rich
in minerals vitamins fiber etc to
overcome this deficiency breeders and
bio technologies have tried to increase
the oils proteins vitamins and mineral
content in the commonly consumed food
without reducing the productivity this
approach is called biofortification
biofortification is the process by which
the nutritional quality of food crops is
improved through agronomic practices
conventional plant breeding or modern
biotechnology biofortification has led
to the development of golden rice and
super banana that is rich in beta
keratin and alpha keratin to overcome
vitamin A deficiency here are some of
the examples of hybrids crops with
improved nutritional quality lysine and
tryptophan rich 3 varieties of maize are
shuck T Rutan and protein ax the high
protein rich old wheat variety
Atlas 66 has been transferred to
currently cultivated varieties iron
fortified rice variety containing over
five times iron and vitamin A has been
developed recently wedge tubal crops
rich in vitamins and minerals have been
released by Indian Agricultural Research
Institute New Delhi these are with him
