Abstract

Increasing production and yield quality of cayenne pepper can be done by assembling superior varieties through plant breeding programs. Information related to genetic diversity and heritability is very important for establishing a variety. This research aims to obtain information about genetic diversity and heritability values in the vegetative characters of the first generation (M1) cayenne pepper mutant genotype. The research was carried out from May to September 2023 at the Wedomartani Experimental Garden, Faculty of Agriculture, UPN "Veteran" Yogyakarta using 70 mutant genotypes (M1) and three comparison varieties, namely Ori 121, Kaliber, and Cempluk for a total of 73 genotypes. The experimental design used was an Augmented Design with a Randomized Complete Block Design (RCBD) as the environmental design. The results of the research show that the characteristics of stem diameter, petiole length and leaf length in cayenne pepper have extensive genetic diversity and have high heritability. These characters can be used as selection criteria because they are more influenced by genetic factors than environmental factors.Keywords: mutation, genetic diversity, heritability INTISARIPeningkatan produksi dan kualitas hasil pada cabai rawit dapat dilakukan dengan perakitan varietas unggul melalui program pemuliaan tanaman.

Abstract

Cayene pepper is national strategic vegetable commodity which is widely consumed by Indonesian. National pepper consumption has increased in line with increasing population so the production and quality of pepper need to be increased for creating national food security. Increasing the production and quality can be achieved through assembling superior varieties using mutation. The objective of this research are to evaluate the  growth response in early stages of two varieties cayenne pepper irradiated using gamma-ray mutagen and determine the optimal dose of gamma-rays that will increase the frequency of mutant occurrence. This study was conducted in May-July 2023 at the nursery in Wedomartani, Sleman using two factor completely randomized design, namely variety (Ori 212 and Caliber) and doses of gamma irradiation (0, 100, 200, 300, 400, and 500 Gy). Our finding showed that growth of cayenne pepper in the early stages was influenced by the interaction between varieties and doses of gamma-ray irradiation. Gamma rays irradiation by using 100 Gy and 200 Gy at Ori 212 variety and the Caliber variety at dose 100 Gy gave positive response to plant growth at early stage compared to controls. At doses of 400 and 500 Gy gamma rays on the Ori 212 variety, the germinated plants were unable to grow and the plants died. The recommended dose of gamma rays that would increase the frequency of occurrence of mutants were 249.97 – 288.48 Gy for the Ori 212 variety and dose of 383.29 – 521 Gy for the Caliber variety.

Abstract

The development of melon varieties (Cucumis melo L.) is not only carried out on improving fruit quality, but also on disease resistance, one of which is gummy stem blight (GSB). Gummy stem blight disease at high levels cause a decrease in quality to loss of yield, so the development of gummy stem blight-resistant varieties is necessary. The study was conducted in July - November 2024 in Desa Bansari, Kecamatan Bansari, Kabupaten Temanggung, Central Java Province. The design used was a single-factor complete randomized block design (RCBD) with three replications using 21 melon genotypes planted in a greenhouse. Based on the incidence and severity of gummy stem blight disease observed in the generative phase through natural infection, it is known that there are very significant differences between the test genotypes. In this experiment, no genotypes were found to be highly resistant to gummy stem blight. Potential genotypes that showed moderate to low levels of disease incidence and severity included genotypes 44 (disease incidence: 53.33% and disease severity: 26%), 27 (disease incidence: 75.00% and disease severity: 25.33%), and 35 (disease incidence: 70.25% and disease severity: 37.00%). The broad-sense heritability values showed high values of 88.9% for disease incidence and 93.9% for disease severity. Potential genotypes from screening could be used in the development of lines for gummy stem blight resistance breeding.
