In all breeding programmes , the plants are hand pollinated to ensure cross pollination between selected varieties, e.g. wheat, rice.

Pollination between two plants can be self-pollination. Explain.

Distingusih between self and cross pollination. Classify them

Plant Breeding: Give examples of high yielding varieties of wheat and rice.

Plant Breeding : Give two examples each :(ii) Semi-dwarf varieties of wheat

State whether the following statements are true or false. Correct the false statements. When polination involves two flowers borne on the same plant, it is called as cross-pollination.

Enlist the steps of controlled cross pollination. Would emasculation be needed in a Cucurbita plant? Give reasons for your answer.

In a monohybrid cross of plants with red and white flowered plants, Mendel got only red flowered plants.On self pollinating these FI plants got both red and white flowered plants in 3:1 ratio.Explain the basis of using RR and rrsymbols to represent the genotype of plants of parental generation.

In order to obtain the FI generation Mendel pollinated a pure-breeding tall plant with a pure breeding dwarf plant. But for getting the F2 generation, he simply self- pollinated the tall FI plants.Why?

Plant Breeding : Give two examples each :(i) High yielding varieties of rice

What is the single term that answers all the following question? OR What decides whether you are blue eyed or brown eyed? OR Why does wheat grain germinate to produce what plant and not rice plant? OR Which acid molecules are present in nuclei of living cells?
