Screening olour mango half-sib progenies for dwarfing, vigour, and climate resilience.

ABSTRACT: Mango (Mangifera indica L.) productivity is limited by large canopy size and the absence of reliable dwarfing rootstocks. The polyembryonic genotype 'Olour' is widely used as a dwarfing and salt-tolerant rootstock, but its zygotic progenies remain underexplored. We evaluated 14 Olour-derived half-sib progenies (5-year-old seedlings) for 40 morphological, physiological, and biochemical traits to identify candidates with dwarfing or vigorous growth tendencies and stress resilience. Multivariate analyses (PCA and hierarchical clustering) revealed substantial variation; the first two principal components explained 26.9% and 13.3% of the variance, respectively (40.2% cumulative). Correlation analysis highlighted bark-to-wood ratio, specific leaf weight, stomatal density, and phenolic accumulati
