dc.description.abstractThe present study entitled “Morphological and molecular characterization of apricot (Prunus armeniaca L.) germplasm” was conducted to evaluate the morphological, biochemical and molecular characteristics of thirty nine apricot accessions during 2022 and 2023. Bulk of the variation was accounted for by the first 12 components in qualitative traits; first 3 components in quantitative traits and first 2 in biochemical attribute which accounted for 79.80%, 68.401%, and 77.117 % of the total variation in a PCA plot, respectively. Phylogenic analysis separated all accessions into two major clusters A and B having 32 and 7 accessions in terms of qualitative traits; 38 and 1 in quantitative and 11 and 28 in biochemical attributes, respectively. Out of 39 accessions only 21 accessions showed promising characters in terms of fruit weight, colour, shape, TSS, and weak adherence to stone that could benefit the farming community. Molecular characterization using 46 SSR markers produced a total of 974 alleles with an average of 33.59 alleles per locus with PIC values ranging from 0.16 to 0.50. PCR product of 15 accessions mostly indigenous collections and also Shakarpara that revealed unique bands were sequenced and subjected to BLAST search which revealed a high degree of homology with a number of Prunus dulcis DNA. A high quality reference genome for apricot is still unavailable thereby limiting the elucidation of the associations of phenotypes with genetic background and varietal diversity in apricots. Hence in order to generate better information for effective genetic diversity assessment there is a need for future sequencing, assembly and annotation of the apricot genome. This will provide more important gene resources for future studies on apricot and will provide a new direction towards future crop improvement programme through breeding.
