Abstract

Peningkatan produktivitas jagung dapat dilakukan melalui perakitan varietas jagung yang memiliki tingkat prolifikasi tinggi. Ketersediaan galur-galur yang memiliki tingkat prolifikasi tinggi dan daya gabung yang baik akan memberikan peluang besar dalam perakitan jagung hibrida prolifik dengan hasil tinggi. Penelitian ini bertujuan memilih galur-galur prolifik yang memiliki daya gabung yang baik pada karakter prolifikasi dan mengevaluasi tingkat prolifikasi dan produktivitas jagung hibrida yang dibentuk dari galur-galur tersebut serta mengetahui aksi gen yang berperan pada karakter komponen hasil. Percobaan dilakukan dua tahap yaitu pembentukan hibrida dari galur-galur prolifik dengan metode testcross dan evaluasi hibrida yang terbentuk dengan menggunakan rancangan alfa lattice dengan tiga ulangan. Hasil penelitian menunjukkan galur G7 memiliki nilai daya gabung umum yang baik untuk karakter persentase tanaman prolifik. Hibrida G35/G102612 merupakan hibrida uji dengan persentase tanaman prolifik tertinggi 55,8%. Hibrida G7/Mal03 dengan hasil biji 12,9 t ha-1 dan persentase tanaman prolifik 53,9% merupakan jagung hibrida prolifik dengan hasil tinggi. Aksi gen non aditif lebih berperan dalam penampilan karakter komponen hasil pada jagung prolifik.AbstractMaize productivity can be increased by improving maize varieties with high prolificacy. The adequate of high prolificacy lines with a good combining ability will provide great opportunities to form a high yield prolific maize. The research aimed to select the prolific line which has good combining ability on the prolificacy and evaluate the prolificacy and productivity of the hybrid maize from these lines and to know the gene action which plays role in the yield component characters. The research was carried out in two stages, i.e. the formation of hybrids from the prolific line using the testcross method and evaluation of hybrids using the alpha lattice design with three replications. The results showed that line G7 had a good general combining ability for the percentage of prolific plants. Hybrid G35/G102612 was the test hybrid with the highest percentage of prolific plants of 55,8%. Hybrid G7/ Mal03 which had the yield of 12,9 t ha-1and percentage of prolific plants 53,9% was the prolific hybrid maize with the high yield. The non-additive effect played the main role for yield component characters of prolific hybrid maize.

Abstract

The improvement of low nitrogen tolerant hybrid maize face on genotype x environment the genotype x environment interaction caused a genotype unable to maintain its appearance under suboptimal conditions. it caused the breeders difficult to choose varieties that are stable at optimal and suboptimal conditions. The using of simultaneous stability analysis methods can provide more authentic stability information. This study aims to 1) determine the yield stability of the promising low N tolerance hybrid maize varieties, 2) to obtain varieties that have high yield and stability and under optimal and sub-optimal conditions. This research was conducted at Bajeng Experimental farm, Gowa, South Sulawesi. The research was arranged in a split-plot design with two replications. Three levels of fertilizer N (N0 = 0 kg N ha-1, N1 = 100 kg N ha-1 and N2 = 200 kg N ha-1) as the main plot and 39 genotypes of maize (36 hybrids resulting from crosses of low N and 3 checks varieties Nasa 29, Bisi 18 and Jakorin 1) as the subplot. The variable measured was grain yield. The yield stability analyses were performed by Francis and Kannenberg, Finlay and Wilkinson, Eberhart and Russel, and GGE Biplot methods. The results showed that there were no genotypes stable in overall the four methods, but three genotypes considered as stable genotype based on two methods. H5, H6 and H15 genotype were the genotypes with high stability and high yield. The three genotypes had the opportunity to be released as a low Nitrogen tolerant maize hybrid.

Abstract

Seleksi langsung hasil biji pada jagung di kondisi Nitrogen rendah seringkali tidak efisien karena heritabilitas hasil biji yang rendah. Oleh karena itu, penggunaan seleksi tidak langsung melalui karakter sekunder perlu diterapkan untuk meningkatkan efisiensi seleksi. Penelitian ini bertujuan untuk mengidentifikasi karakter sekunder yang dapat diaplikasikan dalam seleksi tidak langsung hasil biji jagung pada kondisi N rendah. Penelitian ini dilakukan di IP2TP Bajeng Balai Penelitian Tanaman Serealia Sulawesi Selatan dimulai dari bulan Mei sampai September 2021. Penelitian ini disusun dalam rancangan tersarang menggunakan 72 genotipe jagung dan dua taraf pemupukan N (N1=100 kg N/ha dan N2=200 kg) sebagai perlakuan dengan dua kali ulangan. Tiga parameter, yaitu efisiensi relatif seleksi, heritabilitas dan keragaman genetik diamati untuk menentukan karakter sekunder yang dapat digunakan secara efisien untuk seleksi tidak langsung hasil biji jagung pada kondisi N rendah. Hasil penelitian menunjukkan bahwa karakter yang dapat digunakan dalam seleksi tidak langsung jagung toleran N rendah adalah tinggi tanaman dan tinggi tongkol.

Abstract

Yield maize direct selection at drought conditions sometimes is inefficient. Indirect selection through secondary characters can increase selection efficiency. This study aims to obtain secondary characters that can be used for indirect selection. This research was conducted at IP2TP Bajeng, Indonesia Cereal Research Institute, Gowa Regency, South Sulawesi Province from July to November 2020. The research was arranged in a randomized Alpha Lattice group design with three replications. The genotypes used were 36 hybrid maize candidates and four comparison varieties. Characters that have high diversity are determined by a loading factor value of more than 0.7. The correlation between secondary characters and yield was using Pearson correlation and heritability ​​are derived from the analysis of variance. The results showed that the characters of day to anthesis, day to silk, number of harvested ears and ear diameter were secondary characters that could be used as the indirect selection of maize in drought conditions.   drought;; indirect selection, maize; secondary characters
