Abstract

Penelitian bertujuan untuk mengetahui nilai daya gabung umum, nilai daya gabung khusus, dan kombinasi persilangan antar genotipe jagung manis (Zea mays saccharate) terbaik. Penelitian menggunakan Rancangan Acak Kelompok Lengkap (RAKL) terdiri dari satu faktor dengan tiga ulangan. Perlakuan terdiri dari 10 genotipe, yaitu SB 1-3, KD 1-1, dan 7/5 1-B sebagai tetua, SB 1-3 x KD 1-1, SB 1-3 x 7/5 1-B, KD 1-1 x 7/5 1-B sebagai F1, KD 1-1 x SB 1-3, 7/5 1-B x SB 1-3, 7/5 1-B x KD 1-1 sebagai F1 resiproknya, dan varietas Talenta sebagai pembanding. Data dianalisis keragamannya menggunakan analisis varians (ANOVA). Apabila ada perbedaan signifikan, dilanjutkan dengan analisis dialel metode Griffing-1. Hasil penelitian menunjukkan karakter tinggi tanaman, diameter batang, jumlah daun, dan anthesis silking interval lebih dominan dipengaruhi oleh varian dominan. Sedangkan pada karakter panjang tongkol tanpa kelobot, diameter tongkol tanpa kelobot, bobot tongkol tanpa kelobot, jumlah biji per baris, kadar kemanisan, dan umur panen lebih banyak dipengaruhi oleh varian aditif. Nilai Daya Gabung Umum terbaik dihasilkan dari tetua SB 1-3 dan 7/5 1-B pada lima karakter yang dievaluasi. Nilai Daya Gabung Khusus terbaik dihasilkan dari persilangan SB 1-3 x KD 1-1 dan SB 1-3 x 7/5 1-B pada enam karakter yang dievaluasi. Kombinasi persilangan SB 1-3 x 7/5 1-B merupakan persilangan terbaik yang mempunyai potensial hasil tinggi seperti varietas pembanding.

Abstract

Baby corn is consumed widely in Indonesia, but special corn varieties for baby corn production are not available until now. The objectives of this study were to evaluate phenotypes, estimate the genetic parameters from two generations of selfing and sibbing, and identify the genotypes to develop as baby corn variety. This study was conducted using a completely randomized block design with three replications. Genetic materials used consist of 19 genotypes. They were four genotypes S0, HS1, S1, S2 and three genotypes of HS2. Progenitors(S0) were Laksmi, Golden, Hawaii, and Baruna belonging sweet corn type. Baby corn’s phenotypes from two generations sibbing were more vigor than selfing. Families of HS2 dan S2 have a higher percentage of class A marketable cobs than generations before. Two generations sibbing and selfing increased genetic variances and broad-sense heritability. Families of HS2 had better phenotypic performance than S2, the percentage of class A marketable cobs was higher than S0 and HS1, number of cobs per plant was the highest broad-sense heritability estimation. HS2 families were considered to develop as open-pollinated baby corn varieties.

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. Informasi terkait keragaman genetik dan heritabilitas sangat penting untuk perakitan suatu varietas. Penelitian ini bertujuan untuk mendapatkan informasi tentang keragaman genetik dan nilai heritabilitas pada karakter vegetatif genotipe mutan cabai rawit generasi pertama (M1). Penelitian dilaksanakan pada bulan Mei sampai September 2023 di Kebun Percobaan Wedomartani Fakultas Pertanian UPN “Veteran” Yogyakarta menggunakan 70 genotipe mutan (M1) dan tiga varietas pembanding yaitu Ori 121, Kaliber, dan Cempluk sehingga total terdapat 73 genotipe. Rancangan percobaan yang digunakan yaitu Rancangan Bersekat (Augmented Design) dengan Rancangan Acak Kelompok Lengkap (RAKL) sebagai rancangan lingkungan. Hasil penelitian menunjukkan bahwa karakter diameter batang, panjang tangkai daun, dan panjang daun pada cabai rawit memiliki nilai keragaman genetik yang luas serta memiliki nilai heritabilitas tinggi. Karakter-karakter tersebut dapat dijadikan kriteria seleksi karena lebih banyak dipengaruhi oleh faktor genetik daripada faktor lingkungan. Kata kunci: mutasi, keragaman genetik, heritabilitas

Abstract

One of the horticultural commodities that are in great demand by almost all Indonesian people is red curly chili. For producers, in creating varieties and selling chili seeds, ideally in line with the preferences of chili farmers. The purpose of this study was to determine the preferences of red curly chili farmers. This research was conducted in Semin District, Gunung Kidul Regency, Special Region of Yogyakarta from June to July 2023. The sample selection method was purposive sampling, namely farmers who grow red curly chilies in the area. The type of data is primary, with the data collection method through direct interviews with farmers. Data analysis using Conjoint Analysis. The results showed that the five main priorities of farmers' preferences in cultivating red curly chilies were 1) the color of the chilies, namely red, 2) the shape of the chilies, which was elongated, 3) the age of harvesting chilies ranging from 80-100 days, 4) the size of the chilies 10-15 cm , 5) there is shortening of the chili plants starting from the 3rd branch. Furthermore, farmers tend to like chilies that are resistant to Anthracnose/Patek disease, the fruit has tortuous curvatures, plant height is around 100-150 cm, the plant performance is wide, the chili's shelf life is 7-10 days, the chilies fall off, the chili skin thickness is medium, the surface of the chili is smooth, the taste of the chili is spicy, and it is resistant to grapyak caterpillars and fruit flies.
