Abstract

The prized Red banana, selected for superior qualities, demands strong genetic uniformity for successful clonal propagation and preservation. Ensuring this uniformity early in the growth of in vitro Red banana plants is essential, as gene mutations and chromosome rearrangements during tissue culture can jeopardize both cloning and germplasm conservation. In this situation, molecular markers play a pivotal role in confirming genetic stability. Thus the study aims to discover a marker that identifies tissue-cultured Red bananas from their virescent variants during initial sub-culturing. A marker linked to anthocyanin has been identified which effectively differentiated Red bananas from virescent variants and it was further validated in various banana cultivars, ornamental Musa species and their interspecific hybrids. The PCR-based marker showed remarkable specificity, discerning Red bananas from virescent variants during tissue culture. It also distinguished green and red offspring, cutting time and resource costs, and shortening the banana breeding cycle.
