Genetic parameters, phenotypic diversity, selection differential and gain analysis through EFA, HCA and multivariate analysis for growth, yield and yield components in potato (Solanum tuberosum L)
Potato is a globally significant food crop and a vital source of nutrition, plays a crucial role in food security due to its high productivity, nutritional value and adaptability to diverse agro-climatic conditions. This study was conducted at Horticulture Research and Extension Centre, Haasan during kharif and rabi season of 2021–22, aimed to investigates genetic parameters, phenotypic diversity, selection differential and gain to identify high yielding superior potato genotypes using Pearson's correlation analysis, hierarchical cluster analysis (HCA), principal component analysis (PCA), exploratory factor analysis (EFA) and multi-trait genotype ideotype distance index (MGIDI) analysis to enhance growth, yield and yield components. The pooled ANOVA revealed significant genotypic, environmental and G × E interactions, with stable growth, yield traits and genotype-specific responses for tuber size and weight. Significant positive correlations were found between tuber yield per plant and traits like tuber size (r = 0.52), tuber diameter (r = 0.44) and plant height (r = 0.50). Hierarchical clustering identified 2 major clusters, with Cluster 1 genotypes showing high performance for growth and yield traits. PCA revealed 6 components explaining 81.05 % of variance, with PC1 associated with tuber yield per hectare (0.34), tuber yield per plot (0.34), number of tubers per plant (0.33), and tuber yield per plant (0.33) and PC2 on number of leaves at 75 days after planting (DAP) (0.52), number of internodes (0.49) and number of branches per plant at 75 DAP (0.43), while the PCA biplot grouped genotypes into 4 quadrants, highlighting superior performance in Quadrant II and lower performance in Quadrant IV for growth and yield traits. The factor analysis identified 6 factors influencing growth, yield, and yield components in potatoes. FA1 primarily relates to yield traits, such as tuber yield per hectare (−0.94), number of tubers per plot (−0.87), tuber yield per plot (−0.94), and haulm yield on a fresh weight basis (−0.80).

期刊介绍:
Gene Reports publishes papers that focus on the regulation, expression, function and evolution of genes in all biological contexts, including all prokaryotic and eukaryotic organisms, as well as viruses. Gene Reports strives to be a very diverse journal and topics in all fields will be considered for publication. Although not limited to the following, some general topics include: DNA Organization, Replication & Evolution -Focus on genomic DNA (chromosomal organization, comparative genomics, DNA replication, DNA repair, mobile DNA, mitochondrial DNA, chloroplast DNA). Expression & Function - Focus on functional RNAs (microRNAs, tRNAs, rRNAs, mRNA splicing, alternative polyadenylation) Regulation - Focus on processes that mediate gene-read out (epigenetics, chromatin, histone code, transcription, translation, protein degradation). Cell Signaling - Focus on mechanisms that control information flow into the nucleus to control gene expression (kinase and phosphatase pathways controlled by extra-cellular ligands, Wnt, Notch, TGFbeta/BMPs, FGFs, IGFs etc.) Profiling of gene expression and genetic variation - Focus on high throughput approaches (e.g., DeepSeq, ChIP-Seq, Affymetrix microarrays, proteomics) that define gene regulatory circuitry, molecular pathways and protein/protein networks. Genetics - Focus on development in model organisms (e.g., mouse, frog, fruit fly, worm), human genetic variation, population genetics, as well as agricultural and veterinary genetics. Molecular Pathology & Regenerative Medicine - Focus on the deregulation of molecular processes in human diseases and mechanisms supporting regeneration of tissues through pluripotent or multipotent stem cells.
