Abstract

Wahyu Y, Putri NE, Trikoesoemaningtyas, Sutjahjo SH, Nur A. 2018. Short Communication: Correlation, path analysis, and heritability of phenotypic characters of bread wheat F2 populations. Biodiversitas 19: 2344-2352. Wheat varieties are still limited for Indonesia. A high yield wheat plant is necessary to be assembled by selecting plants from a segregated population. The selection will need information on some characters that contribute to the high yield and the relationship among the observed characters. This study aimed to determine the relationship between characters and the effects of the observed characters to grain yield per plant. This research was conducted from July 2017 to March 2018 at Balithi Experimental Farm (1100 m asl.), Cipanas, Cianjur District, West Java, Indonesia. The genetic material used were three F2 population of bread wheat (G1/Se, HP/Se, and Ja/Se) and four parent genotypes. Observations were made on each individual of F2 populations. Parent genotypes were planted by using completely randomized block design with three replications. The results showed that the number of a grain of non-main spike and the number of grain per plant characters had a high correlation in each F2 population and these characters also had positive and significant direct effect to grain weight per plant. It could be a character selection for high yield breeding program. The broad sense heritability was medium to a high value for all characters in F2 G1/Se and HP/Se populations.

Abstract. Hidayatullah T, Suliansyah I, Swasti E, Putri NE, Mejaya IMJ. 2025. Evaluation of resistance in new hybrid maize genotypes to Northern leaf blight (Exserohilum turcicum). Biodiversitas 26: 4967-4975. Northern Leaf Blight Disease (NLB), caused by Exserohilum turcicum, is a major foliar disease threatening maize (Zea mays) production in Indonesia. This study aimed to evaluate the resistance of 20 new hybrid maize genotypes developed by Universitas Andalas, along with two control varieties, against NLB. Field trials were conducted in West Sumatra using a randomized complete block design to assess disease resistance and agronomic traits. Multivariate analysis was used to assess 20 new hybrid maize genotypes. The collected data were examined across nine parameters: Plant Height (H), Ear Height (EH), Stem Diameter (SD), Dehusked Ear Weight (DEW), Harvest Moisture (HM), Grain Weight per Ear (GWE), 1000-grain Weight (W1000), Yield Potential (YP), and Northern Leaf Blight (NLB). Results showed that most of the hybrids demonstrated Resistance (R) to Moderate Resistance (MR), with genotypes G4-13, G15-16, G18, and G21 exhibiting high levels of resistance and stability. NLB severity showed significant correlations with all parameters except harvest moisture. Principal component analysis identified three components with eigenvalues greater than one, collectively explaining 86.53% of the total variance. The first two components alone accounted for 74.19% of the variance, highlighting their dominant role in discriminating among genotypes. Cluster analysis produced four clusters, such as cluster 1: G7, G12, G3, G14, and G17; Cluster 2: G10, G19, G2, G20; Cluster 3: G21, G6, G22; and the last, Cluster 4: G15, G8, G16, G9, G13, G18, G4, and G5. The findings indicate that G6 is suitable candidates for advancement to preliminary yield trials, combining superior yield potential with notable resistance to NLB. These outcomes provide practical guidance for breeding programs seeking to produce resilient and productive maize hybrids across variable agroclimatic settings.

Abstract

Shallot (Allium ascalonicum L.) is one of the main horticultural commodities that is widely consumed as a condiment after chili. This research focuses on the interaction of the dose of ZA fertilizer with the concentration of ZPT Atonik on the growth and yield of shallot plants. This research was conducted in the experimental garden of Andalas University, Padang with an altitude of ± 383 meters above sea level, from March to May 2025. This experiment used a Factorial Randomized Group Design with two factors. The first factor is the dose of ZA fertilizer 0 kg/ha, 400 kg/ha, 800 kg/ha and the second factor is the concentration of ZPT Atonik 0 cc L-1, 0.50 cc L-1, 1 cc L-1. Data were analyzed by analysis of variance (ANOVA) and further analyzed by Duncan New Multiple Range test (DnMRT) at 5% significance level. The results showed an interaction between the dose ZA fertilizer with a concentration of ZPT Atonik on tuber diameter parameters. Doses of ZA fertilizer gave a significant effect on the number of leaves, number of tubers, fresh weight of tubers per clump, fresh weight of tubers per plot, dry weight of tubers per clump, and dry weight of tubers per plot.
