Abstract

One of the obstacles to melon cultivation is the availability of seeds and the high price of melon seeds. This condition causes the need to assemble superior melon varieties with the expected characters. This study aims to form a pure line of melon with certain superior characteristics and can be proposed as a new high-yielding variety in the open-pollinated category. The research was conducted at the Experimental Garden of the Agrotechnology Study Program, Faculty of Agriculture, Trunojoyo University, Madura, from September-December 2022. This study used a randomized block design method. The treatments used were nine pure lines of melon (PK-669, D-162, PK-361, PK-165, PK-114, D-029, D-5089, PK-211, and comparison). Each treatment was repeated three times, and each experimental unit consisted of 12 plants. Research data were analyzed using analysis of variance (ANOVA) and HSD test α = 0.05. The selection advancement was analyzed by comparing character data for each generation. The research showed that the results of the characterization of ten melon lines S0-S4 generation on the characters of fruit length, fruit diameter, flesh thickness, and melon fruit weight showed a decreasing trend in each generation. The S4 generation (9.17 °brix) in the character of the average sugar content there was an increase that was not significantly different from the S3 generation (9.03 °brix), while the number of seeds in each generation had an average value that was not significantly different but occurred an increase in the number of seeds in the S3 (372) and S4 (381) generations. An increase in one generation of the population in the linear regression equation is estimated to reduce the character of fruit length by 0.50 cm, fruit diameter by 0.465 cm, flesh thickness by 0.140 cm, fruit weight by 0.199 Kg, sugar content by 0.752 °brix, and a number of seeds by 5.4.

S0-S4世代西瓜数量特性
甜瓜种植的障碍之一是种子的可获得性和甜瓜种子的高价格。这就需要选育具有预期性状的优良甜瓜品种。本研究旨在形成具有一定优势特性的甜瓜纯品系,可作为开放授粉类别的高产新品种提出。该研究于2022年9月至12月在马杜拉Trunojoyo大学农学院农业技术研究项目实验园进行。本研究采用随机区组设计方法。采用9个纯品系(PK-669、D-162、PK-361、PK-165、PK-114、D-029、D-5089、PK-211和对照)处理。每个处理重复3次,每个试验单元12株。研究资料采用方差分析(ANOVA), HSD检验α = 0.05。通过对各代性状数据的比较,分析了选择的先进性。研究表明,10个甜瓜品系s0 ~ s4代的果实长、果实直径、果肉厚度、甜瓜果实重等性状的鉴定结果均呈逐代递减趋势。在平均糖含量性状上,S4代(9.17°糖度)与S3代(9.03°糖度)差异不显著,而每代种子数平均值差异不显著,但在S3代(372)和S4代(381)出现了增加。在线性回归方程中,种群每增加一代,果实长减少0.50 cm,果实直径减少0.465 cm,果肉厚度减少0.140 cm,果实重减少0.199 Kg,含糖量减少0.752°brix,种子数减少5.4。
