Karakterisasi dan Evaluasi Keragaman Genotipe Semangka Lokal

Abstract

Characterization is one of the first phases of plant breeding activities of watermelon. The process will trigger the appeareance of genetical diversity of the plants. The information regarding the genetical diversity of the observed characteristics is worthwhile the next phases of the breeding process. The experiment intends to achieve information of genetical diversity and directs for future research of the relations between the genetic relationship between watermelon genotype based on the level dissimilarities. The experiments has been implemented at the University Farm Leuwikopo, Bogor Agricultural University from October 2014 until January 2015. The experiment was arranged in a randomized complete block design with 8 genotypes of the exploration result and 1 genotipe for comparison. The diverse result of the analysis concludes that the test genotypes have certain effects to the observed characteristics. The characteristics of the weight of the fruit, length of the fruit, thickness of the pericarp, the total soluble solid of flesh, the day of flowering, and the harvest day have a high broad sense heritability predictive value. The character of the length of pedicel and the perimeter of fruit have medium broad sense heritability predictive value. Based on the hedonic test, genotype Bengkulu 3 was the only preferred by the panelist due to its color, scents, texture, and the taste of the fruit characteristics. The result of cluster analysis conclude that genotypes originated from same origin generally will be grouped to the group of same genetic relationship.
