Crossing
Crossing is the process of developing new variety by collecting pollen from one rose and distributing it into different rose.
Crossing include several steps to develop new variety.
1. Selection of healthy plant.
2. Emasculation: It is the process removing anther from the flowers of the seed parent with the help of a forceps before anther dehiscence. For emasculation we should choose unopen flower (bud). During emasculation female part of flower should not get damage. The time of emasculation is 7AM to 11AM.
