Arecanut cultivars are generally tall, which is a major
constraint in arecanut cultivation. High yielding tall cultivars
have been crossed with natural dwarf mutant, Hirehalli Dwarf
(HD) and hybrids have been developed and released for
commercial cultivation. It is very difficult to distinguish
selfed progenies of the female mother palm in the nursery
stage using morphological traits. Start Codon Targeted
(SCoT) primers were used to screen tall cultivars of arecanut
and HD. One of the primers, SCoT11, produced an amplicon
of around 1300 bp band, which was present in all the tall
cultivars, but was absent in the dwarf accession. A SCAR
marker, capable of distinguishing tall/dwarf trait in arecanut,
was also developed and validated, which could ensure
supply of genuine hybrid planting material to the farming
community.
