Solutions

Plants developed through suspension cultures generally exhibit genetic variations. Plants generally exhibit cytogenetic and genetic variations, which help the plant breeders in crop improvement. When such variants arise through the cell and tissue culture process using any plant portion as an explant material, variations arising are termed as somaclonal variations. One of the approaches to create somaclonal variations include the growth cell suspension cultures for several cycles.
Question 3/10

In tissue culture, which of the following are true for a suspension culture?
A. Suspension culture consists of single cells and small groups of cells.
B. They must be constantly agitated at 100 to 250 rpm (revolutions per minute).
C. Suspension culture is maintained in a medium usually gelled with agar.
D. The cultures grow in two to three weeks.
E. Usually, the medium has the auxin 2,4-D.

Skipped
D
evaluation and selection of parents

Solutions

In plant breeding programmes, the entire collection (of plants/seeds) having all the diverse alleles for all genes in a given crop is called germplasm collection. A very good collection is helpful in picking up the desired trait for incorporation in new improved varieties.
Germplasm collections can be stored in several ways – as seeds in cold storage, as whole plants in a nursery or orchard or as cryopreserved dormant buds.
