Estimation of genetic variance of some line generation S3 cantaloupensis melon hydroponically based on smart farming system

Abstract

This research aims to examine the genetic variance, heritability value, and the expected genetic progress of the S3 generation melon lines tested so as to determine the potential lines to be used as sources of genetic material in breeding programs. This research was conducted from January to May 2021 in greenhouse CV. Agroniaga. The experimental design used was a Completely Randomized Design (CRD) with a single treatment in the form of a line consisting of 6 levels, namely GR-1-3-7, GR-1-3-8, GR-1-3-20, GR-1-3-22, GR-1-2-2, and GR-1-1-3. Quantitative character observation data were analyzed using ANOVA or F test at 5% significance level. If the F test has a significant effect, then the average value is further tested with the Scott-Knott test. The results showed that the morphology of the S3 generation melon lines showed differences in fruit characters based on net distribution, net intensity, net pattern, fruit aroma, and fruit texture. The value of broad genetic variance was found in the parameters of plant height, male flowering age, harvest age, and fruit weight. High heritability values for male flowering age, female flowering age, harvest age, and fruit flesh thickness. The GR-1-1-3, GR-1-3-22, GR-1-3-7, and GR-1-3-8 lines are lines that have greater potential than other lines in terms of the effectiveness of selection on fruit weight parameters, so it is good to use for the next selection process.
