Exp: Transgenic rice Taipei-309 (Golden rice) carries three genes known as Psy (phytoene synthase), Crt-1(Phytoene desatunase) and Lcy (Lycopene cyclase), all these three genes of function cocoordinately to produce $\beta$-carotene. It is also rich in vitA - Round -up ready soyabean is genetically modified soyabean that is resistant to herbicide glyphosate. - Bt cotton is genetically modified that is resistant to cotton ball worm. - Flavr savr is transgenic tomato are bruise resistant. Hence, it is suitable for storage and have longer shelf life.

The antisense construct of ACC synthase gene (RNA) was used in production of
1 Bt maize
2 Bt cotton
3 Golden rice
4 Flavr savr (tomato)
Explanation:
Exp: The antisense construct of ACC synthase gene (RNA) was used in production of Flavr savr (tomato). - ACC synthase is an enzyme involved in the biosynthesis of ethylene, a plant hormone that regulates various physiological processes. It delays fruit ripening or increasing plant tolerance to stress conditions. Flavr savr tomato was one of the earliest examples of genetically modified food with potential benefits such as reducing food waste by extending the self life of tomato.

DEVINER and COLLEGO are two trade names in agriculture. They are used as:
1 bioinsecticides
2 natural insecticides
3 biofungicides
4 bioherbicides
Explanation:
Exp: Deviner is the bioherbicide used for controlling milk weed vine. Product made up of liquid concentrate of Phytopthora palmivora chlamydospores. Deviner was first bioherbicide registered in United States. - Collego is also bioherbicide made from the anthracnose causing fungal pathogen Coleotricum gleosporiodes used to control Aeschynomene verginica in rice and soyabean crops.

Production of superior $F_1$ hybrids is called
1 inbreeding
2 domestication
3 emasculation
4 heterosis
Explanation:
Exp: Phenotypic superiority of the hybrid over its parents in one or more traits is defined as Heterosis for example :- Mule is both hardier and sturdier than of its. parents. - The process of removing anthers from bisexual flower without affecting female reproductive part is termed as emasculation.
