Abstract. Yuriyah S, Darnaedi D, Setia TM, Windarsih G, Utami DW. 2021. Phenotype and genotype variability of interspecific rice lines related to bacterial leaf blight resistance (Xanthomonas oryzae pv. oryzae) character. Biodiversitas 22: 4123-4130. Wild rice species are the source of the gene pool for rice genetic diversity. The cross-species crosses (interspecific crosses) play an important role in breeding, namely in terms of expanding the diversity of desirable characters, such as disease resistance and improvement in yield potential. Currently, the genes from wild rice species have been successfully introgressed into cultivated rice so that they can overcome the rice production constraints, including the introgression of genes for the bacterial leaf blight (BLB) resistance. The purpose of this study was to analyze the variability of phenotype and genotype performance of lines derived from wild rice species for the character of resistance to BLB disease. A total of 33 selected backcross lines derived from wild rice species of O. rufipogon and O. glaberrima as the donor parents and 2 control varieties (resistant and susceptible to BLB disease), were used in this study. The evaluation of phenotype and genotype of resistance characters to BLB disease was carried out during a vegetative phase of the plant. The resistance evaluation was carried out in a greenhouse, while the genotype performance was analyzed using 4 STS markers linked to Xa4, Xa7, and Xa13 genes. The result of the phenotype evaluation showed that there were variations among the resistance of the tested lines. Three lines derived from a Situ Bagendit/Oryza rufipogon cross were resistant to all BLB races used in the testing. Those three lines indicated to have the allele of the Xa7 resistance gene based on the genotype performance which grouped with the Code variety that had the Xa7 resistance gene.

Abstract. Windarsih G, Utami DW, Yuriyah S. 2021. Morphological characteristics of Zingiberaceae in Serang District, Banten, Indonesia. Biodiversitas 22: 5507-5529. Zingiberaceae, known as ginger family, is a family of monocotyledon belonging to the Zingiberales order. This family is widely used its rhizome for various purposes, especially as medicinal plant. The morphological characters can be used to help the identification of species in the field of plant taxonomy. The aim of study was to characterize the morphological traits, both vegetative and generative organs, of Zingiberaceae from Serang District, Banten. Plant specimens were collected from Serang District, Banten, including in Pabuaran, Gunungsari, and Ciomas sub-district using purposive sampling. The examination of morphological characters data was conducted through observation and documentation. There were 13 species/varieties of Zingiberaceae collected from the studied area, i.e. Amomum compactum, Alpinia purpurata, Curcuma xanthorrhiza, C. longa, C. heyneana, C. mangga, C. aeruginosa, Kaempferia rotunda, Etlingera elatior, Zingiber zerumbet, Z. officinale, Zingiber officinale var. rubrum, and Z. cassumunar, in which the generative organs were found only in eight species/cultivars of them. Based on the morphological characters of vegetative organs, thirteen species/cultivars had a similarity distance coefficient from 37% to 94%; while based on the morphological characters of both vegetative and generative organs, the eight species/cultivars had a similarity distance coefficient from 31% to 94%. The results showed that using the characters of vegetative organs data were still able to provide consistent grouping results with the generative organs.
