Abstrak

Zoysiagrass is warm-season turfgrass thriving in tropical regions. Despite the adaptive nature, the existence of Indonesian zoysiagrass as well as morphological and genetic characteristics are not available. Therefore, this study aimed to explore Indonesian zoysiagrass from western and eastern parts of the country, as well as its morphological and molecular characteristics. Morphological characteristics was conducted to measure vegetative and reproductive characters while genotyping was performed using 15 simple sequence repeat markers. Morphological characteristics cluster three major groups, namely Group 1 corresponded to short, shorter, and fine leaves. Group 2 corresponded to tall, longer, and fine leaves, fewer seeds, and short spikelet, while Group 3 corresponded to tall, long, and wider leaves, more seeds, and longer spikelet. The results showed that the expected heterozygosity (He = 0.256) was lower than homozygosity (Ho = 0.341). The high level of discriminating capacity, polymorphism, and informativeness of SSR marker was observed (Effective Multiplex Ratio = 4.20, Marker Index = 2.394, and Resolving Power = 1.574). Additionally, population structure generated two subpopulations. Group 1 corresponded to Z. japonica from Sumatera Island and mixed province while Group 2 corresponded to Z. japonica from Central Java and Bali with Z. japonica and Z. matrella from mixed province. In conclusion, the exploration of morphological and genetic diversity from Indonesian zoysiagrass provided useful insight for conservation and future breeding improvement.
