Question

During artificial hybridisation experiments, if the female parent produces unisexual flowers
1.There is no need for emasculation
2.The female flower buds are not bagged before the flowers open
3.Emasculation is mandatory
4.Flowers are not rebagged after pollination by desired pollen​

Answer 1

Answer:

first option is correct

Answer 2

1. There is no need for emasculation

Explanation:

Artificial hybridization is a method to improve the plant breed by crossing two plants of desired characters.

• When female parent producing unisexual flowers:

 The emasculated flower is immediately enclosed in a bag to prevent pollination by unwanted pollen. This process is known as bagging. Then, mature and viable grains are collected from male part, the bag is opened and pollen grains are dusted on the stigma. If the female parent produces unisexual flowers then emasculation is not needed. The unisexual flower is bagged before the flowers open.
