| dc.description.abstract | PKHT CK1 merupakan cabai merah keriting dengan sifat toleran suhu
tinggi, namun produksinya masih rendah. Salah satu cara untuk memperbaiki
genetik tanaman adalah dengan induksi mutasi fisik iradiasi sinar gamma.
Penelitian ini bertujuan menghasilkan karakter baru dari tanaman cabai PKHT CK1
dengan perlakuan mutasi iradiasi. Penelitian dilakukan pada bulan November 2022
hingga April 2023 di Kebun Pusat Kajian Hortikultura Tropika (PKHT) dan
Laboratorium Pemuliaan Tanaman AGH. Penelitian ini menggunakan rancangan
kelompok lengkap teracak dengan faktor tunggal dosis iradiasi sinar gamma dan
tiga ulangan. Bahan genetik yang digunakan adalah benih cabai merah keriting
PKHT CK 1 dengan perlakuan iradiasi dosis 0 Gy (kontrol), 100 Gy, 150 Gy, dan
200 Gy. Berdasarkan penelitian, perlakuan iradiasi sinar gamma berpengaruh nyata
terhadap keragaman karakter jumlah biji per buah, namun mengakibatkan
penurunan nilai rata-ratanya seiring dengan penambahan dosis iradiasi. Dosis 150
Gy berpotensi menghasilkan keragaman yang tinggi dikarenakan menghasilkan
nilai koefisien keragaman terbesar khususnya pada karakter-karakter produksi,
yaitu lebar kanopi tanaman, tinggi tanaman, diameter batang, bobot per buah, dan
jumlah biji per buah. | id |
| dc.description.abstract | PKHT CK1 is a curly red chili with high temperature tolerant properties,
but its production is still low. One way to improve plant genetics is by induction of
physical mutations of gamma-ray irradiation. This study aims to produce new
characters from PKHT CK1 chili plants with irradiation mutation treatment. The
study was conducted from November 2022 to April 2023 at Tropical Horticultural
Studies Center (PKHT) field and AGH Plant Breeding Laboratory. This study used
randomized complete block design with a single factor of gamma-ray irradiation
dose and three repeats. The genetic material used was PKHT CK1 curly red chili
seeds with irradiation treatment doses 0 Gy (control), 100 Gy, 150 Gy, and 200 Gy.
Based on research, gamma ray irradiation treatment has a significant effect on the
average number of seeds per fruit thus resulting in a decrease in the number of seeds
per fruit as the irradiation dose increases. Dose of 150 Gy has the potential to
produce high diversity because it produces the largest diversity coefficient value,
especially in production characteristics, namely plant canopy width, plant height,
stem diameter, weight per fruit, and number of seeds per fruit. | id |
