Genetic Variation, Heritability, Principal Component Analysis, Correlation and Path Coefficient Analysis in the Fruit Samples of Sechium edule (Jacq.) Sw. Genotypes

Genetic diversity, heritability, the genetic advance of yield, and associated traits are some important criteria to generate basic information related improvement crops. Some characters Sechium edule (Jacq.) Sw. genotype fruits have been evaluated for their purpose. Genotypes fruit samples were randomly collected such as length (FL), width (FW), circumference/girth (FC), number ridges (FR) from various parts village Kigwema Kohima district, Nagaland at a mean value latitude (25.60690 N), longitude (94.34250 E) altitude (1538 masl) collection trait study normally distributed in histogram plot normality test. Analysis variance (ANOVA) estimated significant differences sample traits. The phenotypic coefficient variation (PCV) was greater than genotypic (GCV) all recorded maximum length, while heritability circumference. High high estimates circumference suggest that it could be considered further through breeding programs. Principle component analysis (PCA) showed numbers responsible most variations observed morphology its improvement. Fruit correlation direct indicated towards effect on selection
