Multivariate Analysis of 31 Phenotypic Traits Among Major Parental Lines of Sugarcane Breeding Programs in China

Abstract

Lebanese mountain Baladi goats are endemic to Lebanon. However, few available genetic data on Baladi population is available. Information based on morphological and biochemical markers exists but yet remains imprecise. The aim of this study is to characterize the morphological and genetic traits of the Lebanese mountain Baladi population. The experiment was carried out in two different regions: Deir El Ahmar(1450m) and Boksmaya (400m). A total of 47 does, aging between 2-3 years, were studied; 9 quantitative traits and 5 qualitative traits were measured on each doe. The doe's genomic DNA was extracted and amplified by using PCR with a panel of 10 ISSR microsatellite markers along with collecting phenotypic data from each animal. The results revealed the presence of two main clusters both genetically and morphologically: CI and CII where most of CI animals produced a lower quantity of milk compared to CII. The mean value for all quantitative traits, except barrel length, showed a superior significant difference between groups (p≤0.05). A positive correlation between the percentage of polymorphism, quantity of milk, ears and head color in both groups was observed. This attempt was to genetically characterize Lebanese Baladi population and to correlate its phenotype with its genotype.

Assessment of the Genetic Diversity of New Sugarcane Hybrids Using Principal Component and Cluster Analyses

“…Biotechnology has provided breeders with a large number of DNA-based markers to analyze the genetic diversity of sugarcane (Junior et al, 2020;Emegha et al, 2021). Phenotypic traits to estimate this type of diversity are now widely used because, compared to molecular markers, they are simple, easy to identify and collect, inexpensive, effective and practical (Wu et al, 2021).…”
