Abstract

Jagung manis (Zea mays var. saccharata Sturt) merupakan salah satu sayuran
yang banyak diminati oleh masyarakat Indonesia. Seleksi tanaman merupakan
salah satu tahapan yang penting dilakukan dalam pemuliaan tanaman untuk
memperbaiki karakter tanaman. Tujuan dari penelitian ini adalah untuk
mengetahui keragaman genetik, nilai duga heritabilitas, kemajuan seleksi dan
calon tetua dari galur jagung manis generasi S-2. Penelitian ini dilaksanakan di
Kebun Percobaan Fakultas Pertanian UPN "Veteran" Yogyakarta pada bulan
Maret sampai dengan Juni 2021. Rancangan percobaan yang digunakan adalah
Rancangan Acak Kelompok Lengkap (RAKL). Perlakuan yang digunakan 9
galur jagung manis generasi S-2 meliput CMP-2A/51, CMP-3/63, CMP-5/49,
CMP-6/7, CMP-8/1, CMP-9B/56, TMR-1/20, TLT-2/43, dan SBO-2/25. Data
dianalisis dengan menggunakan sidik ragam taraf 5 %. Apabila dalam analisis
ragam terdapat peubah yang berbeda nyata maka dilakukan uji lanjut Scott
Knott. Data juga dianalisis dengan menggunakan pendugaan keragaman genetik,
heritabilitas dan kemajuan seleksi. Hasil Penelitian menunjukkan nilai koefisien
keragaman genetik tinggi pada parameter tinggi letak tongkol dan bobot tongkol
tanpa kelobot. Nilai heritabilitas tinggi pada tinggi tanaman, jumlah daun, umur
berbunga jantan, umur berbunga betina, tinggi letak tongkol, bobot tongkol
tanpa kelobot, diameter tongkol, panjang tongkol, dan jumlah baris biji. Nilai
kemajuan genetik harapan tinggi pada parameter tinggi tanaman, tinggi letak
tongkol dan bobot tongkol tanpa kelobot. Galur yang berpotensi dapat dijadikan
calon tetua adalah CMP 9B/56 dan CMP 2A/51.

ABSTRACT
Sweet corn (Zea mays var. saccharata Sturt) is one of the most popular
vegetables in Indonesia. Plant selection is one of the important stages in plant
breeding to improve plant character. The purpose of this study was to determine
genetic diversity, heritability predictability, selection progress and prospective
parents of the S-2 generation sweet corn. This research was conducted at the
Experimental Garden of the Faculty of Agriculture, UPN "Veteran" Yogyakarta
from March to June 2021. The experimental design used was a Randomized
Completely Block Design (RCBD). The treatments used were 9 sweet corn
strains of the S-2 generation including CMP-2A/51, CMP-3/63, CMP-5/49,
CMP-6/7, CMP-8/1, CMP-9B/56, TMR-1/20, TLT-2/43, and SBO-2/25. The
data were analyzed using the variance level of 5%. If in the analysis of variance
there are variables that are significantly different, Scott Knott's further test is
carried out. Data were also analyzed using estimates of genetic varian,
heritability and selection progress. The results showed that the value of the
coefficient of genetic varian was high on the parameters of the height of the cob
location and weight without corn husk. High heritability values were plant
height, number of leaves, age of male flowering, age of female flowering, the
height of cob location, weight without corn husk, diameter of ear, length of ear,
and number of rows of seeds. The value of genetic progress was high on the
parameters of plant height, cob height and weight without corn husk. The line
that has the potential to be used as a candidate for parentage is CMP 9B/56 and
CMP 2A/51.
