The Cluster of Local Maize Accessions Based on Seed Characteristics from North Sumatra

Abstract

T HE use of local maize is still in high demand by farmers in Indonesia. The development of local maize needs to be discovered through a morphological approach. This study was to obtain seed characteristics and similarities of local maize from North Sumatra. Local maize accession seeds were taken by four districts/cities (Binjai, Serdang Bedagai, Deli Serdang, and Mandailing Natal) from North Sumatra, Indonesia from July to September 2022. A hybrid variety of maize was selected for comparison. Seed characteristics were measured in each accession with four replications. A descriptive-analytic method was selected in this study and data were analyzed using one-way ANOVA and followed by Tukey at P<0.05. Correlation analysis, similarity matrix, hierarchical cluster, and constellation plot were constructed in this study. The results showed that SB-1; DS-3; SB-4; and SB-2 accessions had higher seed characteristics than other accessions. The SB-5 accession had the nearest neighbors (0.743) and two accessions (BI-1; DS-2) were classified into one cluster with a hybrid variety. This finding indicates that several local maize accessions are nearest to the hybrid characteristics. A novelty of this study informed that local maize had an opportunity to be used in the fields.

Preliminary Identification of Local Maize Under Drought Stress By PEG-6000

“…The collection of local maize (L) seeds refers to [11] from 4 districts/cities in North Sumatra. A total of 16 local maize seed collection locations from Binjai (LB1, LB2, LB3), Serdang Bedagai (LSB1, LSB2, LSB3, LSB4, LSB5), Deli Serdang (LDS1, LDS2, LDS3, LDS4, LDS5), and Mandailing Natal (LMN1, LMN2, LMN3), North Sumatra Province, Indonesia, as well as a hybrid variety (H) of BISI-79 was selected for comparison.…”
