Yield performance and agronomic character association in soybean genotypes

Abstract

The aim of this research was to evaluate the performance of yield and yield components of soybean genotypes, as well as the relationship pattern among characters that affect the seed yield. The research material consists of 145 F5 lines and five check cultivars, which were evaluated for their yield and yield components in Malang and Probolinggo, using a randomized block design with two replicates. The combined analysis of variance for yield and yield component showed a significant interaction effect between location and genotype for the number of branches, the number of empty pods, 100 seed weight, and seed yield. The performance of yield and yield components of soybean genotypes tested in Malang showed earlier maturity, taller plants, larger seed size, and higher seed yields when compared to research conducted in Probolinggo. In the selection for the best genotypes, ten genotypes were chosen for their large seed size criteria, while two genotypes were chosen for their relatively medium maturity (81 days) in the location of Malang. In Probolinggo, of the ten genotypes, three genotypes with medium maturity, and three genotypes with medium seed size. The selected genotypes will proceed to the stage of the advanced yield trial. The association study revealed that soybean yield has a positive correlation with plant height, number of nodes, number of branches, number of filled pods, days to flowering, and days to maturity. Those yield components could be used as selection criteria in the breeding program to obtain high-yielding soybean cultivars.

Evaluation of Novel Soybean Genotypes for Yield, Yield components, Seed Quality and Resistance to Cotton Leafworm

“…Both growth and yield traits were emphasized by Haspari et al (2021) as selection criteria in soybean breeding programs for developing high yielding genotypes.…”

“…The evaluation of the current 16 soybean genotypes revealed significant differences, as H6L159 and H7L165 produced the highest number of branches, surpassing the two commercial varieties; Giza 111 and Crawford. Both Minmin et al (2020) and Haspari et al (2021) strongly recommended selecting for high branching soybean genotypes through developing new high yielding varieties. In addition, Minmin et al (2019) emphasized the key role of number of soybean pods as well as 100-seed weight in the formation of final yield.…”

Morfologi, Hasil, dan Korelasi Organ Vegetatif dan Generatif Tanaman Kedelai Varietas Wilis di Tanah Masam pada Musim Hujan

“…Dari penelitian ini diperoleh informasi bahwa peubah dari bobot kering akar, bobot kering polong, dan bobot kering batang dan cabang dapat menjadi penciri dari kedelai toleran tanah masam dan musim hujan. Walaupun hasil penelitian ini agak berbeda dari yang ditemukan oleh Hapsari et al (2021) bahwa penciri kedelai unggul adalah tinggi tanaman, jumlah polong terisi, jumlah buku dan jumlah cabang, hari berbunga dan hari masak.…”
