Morphological and yield characterization of 918 M3 garlic putative mutants
through the Allium spp. descriptor lists developed by the International Plant Genetic
Resources Institute (IPGRI) were studied at the experimental area of Mariano Marcos
State University’s Crop Research Laboratory, Tabug, City of Batac, Ilocos Norte. The
study aimed to (1) morphologically characterize the garlic putative mutants using
Allium spp. descriptor lists developed by the International Plant Genetic Resources
Institute (IPGRI); (2) describe the growth and yield characteristics of the garlic putative
mutants; and (3) identify the relationship between bulb weight and growth and yield
characteristics. The experimental design that was used in the study was Descriptive
Research Design and Correlation Analysis. The results of the study showed variations
in growth characteristics, yield characteristics, and bulb characteristics among M3
garlic putative mutants. GC-7-19-3 had the widest laminar width, while GC25-8-1 had
the longest length. GC-4-4-8 had the widest equatorial diameter, the most number of
outer cloves, and bulb weight. Bulb weight was significantly correlated with plant
height and polar diameter, while equatorial diameter and number of outer cloves were
positively correlated with bulb weight. The study found significant variability in
growth potential among putative mutants, with GC4-4-8 showing the highest yield
potential. Plant height, polar diameter, equatorial diameter, and number of outer cloves
positively correlated with bulb weight aiding breeders in improving yield.
