  A collection of all the alleles of all the genes of a crop plant is called (a) germplasm collection                                              (b) protoplasm collection (c) herbarium                                    (d) somaclonal collection

Answer:

                  (a) Germplasm collection is the entire collection of plants/seeds having all the diverse alleles for all genes in a given crop. The given definition does not fit in other options because protoplasm collection deals mainly with collection of protoplast, i.e. plantcell without cell wall. A herbarium is a museum of preserved plants that are used for botanical research, mainly in identification and classification of plants. Somaclonal collection involves plants produced from a single cell which are genetically variable from their parents.
