Among the edible oilseed crops, rapeseed-mustard occupies a prominent position in India accounting nearly 6 million hectares of land under cultivation which produces approximately 5.8 million tonnes of oil seeds annually. In India, it is an important cooking medium and a source of dietary fat for majority of the population inhabiting northern, western and north-eastern states.

Identification and cloning of a new blast resistance gene Pi54 from rice and its utilization in rice improvement

Rice (Oryza sativa) is one of the important crops cultivated and consumed throughout the world. About 90% of rice grown in the world is produced and consumed in Asian region. Though, many high yielding varieties of rice are available, the yield potential of these varieties is considerably affected by various biotic and abiotic stresses. Among the various biotic stresses, like bacterial leaf blight, sheath blight and stem borer limiting rice productivity, rice blast caused by Magnaporthe oryzae (Pyricularia oryzae) is a serious constraint in rice production at global level.

Mustard Hybrids

Brassica juncea (Indian mustard) is the most important oil seed crop of northern India. It is cultivated on ca. 6 million ha and contributes approximately 5.8 million tons to the oilseed pool of India. The productivity of mustard in India is low with an average yield about 1 ton/ha. Intervarietal crosses show 30-60% heterosis for yield. Hence, development and deployment of hybrids could lead to increased production and productivity. The crop is ideally suited for hybrid production as it is amenable to cross pollination by honeybees.

Bt Brinjal

Brinjal is an important vegetable crop of India. It is a good source of vitamin and minerals, especially iron. The area under brinjal cultivation is estimated at 0.55 million hectares with a total production of 8.2 million tonnes. A total of 1.4 million small, marginal and resource-poor farmers grow brinjal. Brinjal is very susceptible to an insect pest namely Brinjal Shoot and Fruit Borer (BSFB). BSFB causes significant losses of upto 60 to 70%. Because of the cryptic nature of the pest the insecticide applications become ineffective.

Bt Tomato

Tomato is the world’s largest vegetable crop after potato and sweet potato. It ranks first in the list of canned vegetables. Tomato is also an important vegetable crop in India, grown in an area of approximately 0.55 million ha producing about 10 million tonnes per annum. This is one of the most important “protective foods” because of its special nutritive value. It has wide range of food uses other than as cooked vegetable like salad, soup, pickles, ketchup, puree, sauces etc. Tomato has very few competitors in the value addition chain of processing.
