Study of Genetic Variability and Diversity in Maize (Zea mays L.) Inbred Lines | Current Journal...

The goal of this study was to gain a better understanding of the genetic characteristics and genetic diversity among the eighteen maize inbred lines, which is crucial for evaluating breeding strategies and predicting hybrid performance. The inbred lines under investigation showed a wide range of diversity. Plant height, ear height, grain yield per cob, cob length, and number of kernels per row showed a medium to high range of PCV and GCV estimates, heritability, and genetic advance as a percent of mean for traits like plant height, ear height, grain yield per cob, cob length, and number of kernels per row. As a result, these qualities are critical for genotype selection in order to increase maize production. Cluster II had the greatest intra-cluster distance (60.49), while cluster I had the smallest (43.81). Solitary clusters are clusters III, IV, V, and IV. Cluster IV and V had the greatest inter cluster distance (386.89), followed by Cluster I and IV (326.90), Cluster I and VI (309.98), Cluster II and V (297.76), Cluster III and V (239.32), and Cluster I and III (239.32). (252.68). It will be rewarding to generate high heterotic hybrids in maize using inbreds such as lines from cluster I and testers from clusters III, IV, and VI, as well as lines from cluster II and clusters III and V.
