Abstract

Efforts to minimize failure in melon cultivation can be done by implementing a smart farming system. Increasing the yield and quality of melons can be done by making hybrid varieties. The genetic diversity of the breeding material is very important in the basic population formation stage. This study aims to examine the genetic diversity and heritability of each melon strain S3 generation, so as to determine the strain of the potential to be used as the source material of genetic in the course of breeding. Research is conducted in Greenhouse CV. SG Agroniaga, Maguwoharjo Village, Depok District in the month January 2021 until May 2021. The design of the experiment that used is Complete Randomized Design (CRD) by treatment of a single form of genotypes which consists of 6 levels ie 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. Each treatment was repeated up to 4 times, so there are 24 units of trial. Each experimental unit consisted of 10 plants. The results showed that the morphology of the S3 generation melon strain in the generative phase contained differences in fruit characters based on net distribution, net intensity, net pattern, fruit aroma, and fruit texture. The value of genetic diversity on the parameters of plant height, male flowering age, harvest age, and fruit weight has a wide genetic diversity. The value of the high percent heritability for the characters of male flowering age, female flowering age, harvest age, and thickness of fruit flesh. The GR-1-3-20 and GR-1-1-3 lines are lines that have greater potential than other lines in terms of selection effectiveness on the parameters of male flowering age and fruit weight, so they are good to use for the next selection process.
