The tiger nut is a valuable crop that has been overlooked and underutilized. The
tubers of this plant are highly valued for their nutritional benefits and health
advantages. This study aimed to evaluate the genetic potential of 42 tiger nut
genotypes using a multitrait index based on factor analysis and genotype-ideotype
distance (MGIDI). The experiment involved a randomized complete block design with
three replications, assessing 10 agronomic and tuber yield traits. The results
showed significant variations among genotypes for all traits, which indicates the
presence of genetic potential that can be harnessed for crop enhancement. The
MGIDI index provided an increased total genetic gain of 78.58% for the desired
traits. Specific genotypes, including PUT-b (FA1), ADU-b (FA2), OBR-B, ENK-B,
ASU-b (FA3), and BEP-B (FA4), were identified as the top candidates for
simultaneous improvement of the measured traits in tiger nut. This demonstrates
the efficiency of the index in selecting superior genotypes, offering a
data-driven approach to breeding programs aimed at optimizing tiger nut yield and
quality. Furthermore, the identification of specific high-performing genotypes
provides valuable genetic resources for future research and commercial
cultivation. These findings contribute to the broader goal of improving food
security and diversifying agricultural production. By promoting the genetic
enhancement of tiger nut, this study supports its potential as a sustainable crop
with significant nutritional and economic benefits.
