Judul: Evaluation of Performance and Yield of Hybrid Sweet Corn (Zea mays saccharata Sturt.) from IPB Breeding Results
Abstrak: Evaluation of performance and yield is essential in plant breeding activities. This study aims to evaluate the performance and obtain the yield of hybrid sweet corn due to IPB breeding. The research was conducted from January 2023 to April 2023 at the Pasir Kuda PKHT and the AGH IPB Plant Breeding Laboratory. The study consisted of one factor, namely 14 genotypes of hybrid sweet corn. The experiment used a completely randomized block design (RCBD) with three replications. The results showed differences in performance and yield between sweet corn genotypes. Genotype significantly affected all quantitative characters observed except for Anthesis Silking Interval (ASI), Total Dissolved Solids (TDS) characters, and seed width. Based on the research results, genotypes SM9.3A.1 x SB.13.1.4, genotypes SB.13.1.3B x T10.97B, and genotypes T10.97B x SB13.1.3B have productivity between 19.01-20.6 tons per hectare higher than the comparison variety Talenta of 13.68 tonnes. The Exsotic control variety had the highest productivity among the test genotypes at 21.33 tonnes. However, it was not significantly different from the T10.97B x SB13.1.3B genotypes, with 20.6 tonnes per hectare productivity. The harvesting age of the test genotypes ranged from 72-75 DAP, and the control varieties ranged from 72-73 DAP. The test genotypes had varying sweetness levels from 11.03-16.57 brix, while the control varieties only ranged from 12.60-12.63 brix., Evaluasi keragaan dan daya hasil penting dalam kegiatan pemuliaan tanaman. Penelitian ini bertujuan mengevaluasi keragaan dan memperoleh daya hasil jagung manis hibrida hasil pemuliaan IPB. Penelitian dilaksanakan pada bulan Januari 2023 sampai April 2023 di Kebun Percobaan PKHT Pasir Kuda dan Laboratorium Pendidikan Pemuliaan Tanaman AGH IPB. Penelitian terdiri dari satu faktor yaitu 14 genotipe jagung manis hibrida. Percobaan menggunakan rancangan kelompok lengkap teracak (RKLT) dengan tiga ulangan. Hasil penelitian menunjukkan terdapat perbedaan keragaan dan daya hasil antara genotipe jagung manis. Genotipe berpengaruh nyata terhadap semua karakter kuantitatif yang diamati kecuali pada karakter Anthesis silking interval (ASI), Padatan Terlarut Total (PTT), dan lebar biji. Berdasarkan hasil penelitian genotipe SM9.3A.1 x SB.13.1.4, genotipe SB.13.1.3B x T10.97B, dan genotipe T10.97B x SB13.1.3B memiliki produktivitas antara 19,01-20,6 ton.ha-1 lebih tinggi daripada varietas pembanding Talenta sebesar 13,68 ton.ha-1. Varietas pembanding Exsotic memiliki produktivitas paling tinggi diantara genotipe uji sebesar 21,33 ton.ha-1, namun tidak berbeda nyata terhadap genotipe T10.97B x SB13.1.3B dengan produktivitas sebesar 20,6 ton.ha-1. Umur panen genotipe uji berkisar 72-75 HST dan varietas pembanding berkisar 72-73 HST. Genotipe uji memiliki tingkat kemanisan yang bervariasi dari 11,03-16,57 brix, sedangkan varietas pembanding hanya berkisar 12,60-12,63 brix.

Judul: Performance Evaluation and Power Yield on  11 Hybrids Sweet Corn Genotypes (Zea mays saccharata. Sturt) Breeding Results of IPB University
Abstrak: Informasi keragaan dan daya hasil diperlukan dalam merakit varietas unggul baru. Penelitian ini bertujuan mengevaluasi keragaan dan daya hasil jagung manis hibrida harapan IPB. Penelitian dilakukan pada bulan Desember 2022 sampai Februari 2023 di Kebun Percobaan Leuwikopo, Dramaga, Bogor, Jawa Barat. Penelitian terdiri dari satu faktor yaitu genotipe sebanyak 13 genotipe jagung manis hibrida. Penanaman dilakukan menggunakan rancangan kelompok lengkap teracak dengan 3 ulangan dari 20 tanaman per satuan percobaan. Hasil menunjukkan bahwa terdapat perbedaan keragaan dan daya hasil antar genotipe jagung manis hibrida IPB dan varietas jagung manis pembanding. Genotipe berpengaruh sangat nyata terhadap semua karakter yang diamati, kecuali diameter batang dan anthesis silking interval. Genotipe SB.13B X SM.9.3A.1 dan SB.5.1B.3B X T.13.1.8 memiliki beberapa keunggulan pada karakter seperti produktivitas, bobot tongkol tanpa kelobot, dan anthesis silking interval yang setara atau lebih baik dari varietas pembanding. Kedua genotipe hibrida harapan IPB ini memiliki produktivitas berkisar 19,04-20,42 ton per hektar sedangkan varietas pembanding berkisar antara 21,06-23,71 ton per hektar. Bobot tongkol tanpa kelobot kedua genotipe IPB berkisar 257,33-261,85 gram sedangkan varietas pembanding berkisar antara 249,13-253,53 gram., Information about performance and power yield of sweet corn is needed in assembling new superior varieties. This research aims to evaluate the performance and power yield of the expected hybrid sweet corn from IPB. The research was conducted from December 2022 to February 2023 at the Leuwikopo Experimental Garden, Dramaga, Bogor, West Java. The research consisted of one factor, which was the genotypes of 13 hybrid sweet corn genotypes. Planting was done using a randomized complete group design with three repetitions where each experimental unit consists of 20 plants. The results showed that there were differences in performance and power yield among the genotype sweet corn hybrids of IPB and comparison sweet corn varieties. Genotype had a very significant effect on all the characters that observed, except stem diameter and anthesis silking interval. The SB.13B X SM.9.3A.1 genotypes and SB.5.1B.3B X T.13.1.8 genotypes had several advantages of characters such as productivity, ear weight without husk, and anthesis silking interval which were equal or better than the comparison varieties. Genotypes SB.13B X SM.9.3A.1 and SB.5.1B.3B X T.13.1.8 had productivity ranging from 19.04 to 20.42 tons per hectare while comparison varieties ranged from 21.06-23.71 tons per hectare. The ear weight without husk of genotypes SB.13B X SM.9.3A.1 and SB.5.1B.3B X T.13.1.8 ranged from 257.33 to 261.85 grams while comparison varieties ranged from 249.13-253.53 grams.
