Question

Describe the components of artificial hybridisation

Answer 1

hi,

here is your answer,

In addition, dissecting genetic components of heritable traits also relies on the development of large mapping populations. Artificial hybridization is the critical initial step in these processes. ... The impacts of operator, pollination time, flower integrity, genotype and environment on hybridization were evaluated.

Answer 2

The process by which only desired pollen grains are used for pollination and fertilization.

The techniques include :

1) Emasculation

Removal of anthers from bisexual flowers of female parent plant.

It is done before anthers mature.

It prevents self pollination thus allowing for cross pollination which improves the quality of what is produced.

2) Bagging

Covering of the emasculated flower to prevent contamination by unwanted pollen grains.

The desired pollen grains are then dusted on the stigma and then flowers are bagged again.

In this way the plant quality is improved.
