Solution(By Examveda Team)

First time cytoplasmic genetic male sterility is used in Onion.
Background. Joseph Gottlieb Kölreuter was the first to document male sterility in plants. In the 18th century, he reported on anther abortion within species and specific hybrids. It is total or partial male sterility in plants as the result of specific nuclear and mitochondrial interactions.
Cytoplasmic male-sterility (CMS) has been used in F1 hybrid seed production in onion (Allium cepa L.). Two types of CMS (CMS-S and CMS-T) have been reported in onions. Almost complete mitochondrial genome sequences of normal, CMS-T and CMS-S cytoplasm types have been obtained in previous studies.
