Question

In which crops, is the method of mass selection applied?
A. Cross pollinated
B. Self-pollinated
C. Both self and cross-pollinated
D. Potato and sugarcane

Answer 1

Hint: Mass selection is a method which is used to improve the quality of crops and is a common, old method where a new variety of plant growth is seen. The mass selection method is applied in both self and cross pollinated plants.

Step by step answer:The method of selection depends on the selection of the plants which is according to the phenotype performance. The seed which is selected from the plants are bulked and is stored for the next generation which is used to improve the overall production of the population by the positive or the negative mass selection, the mass selection is an effective method for the improvement of the landraces and is applied only to a limited degree in the self-fertilizing plant, it is only effective for the high heritable traits, there is a large influence on the environment that is on the development, phenotype and the performance from the one shortage of mass selection. Which is also an advantage that the varieties can be selected for the local performance. The mass selection is practiced in the cross-pollinated crops and the self-pollinated crops which are selected for the phenotype appearance, which is done for the observable characteristic of the plant such as the height of the plant, grain size, etc.
Hence, the correct option is ‘C’.

Note:Mass selection is the simplest, common, and older method to improve the quality of the crop, where the large number of plants which are similar in phenotype are selected and the seed which is harvested are then mixed for a new variety, the plants are selected on their phenotype appearance and is practiced in the cross-pollinated crops and the self-pollinated crops.
