Abstract. Sadiyah H, Ashari S, Waluyo B, Soegianto A. 2021. Genetic diversity and relationship of husk tomato (Physalis spp.) from East Java Province revealed by SSR markers. Biodiversitas 22: 184-192. This study aimed to investigate the genetic diversity and relationship of Physalis spp. from East Java province, Indonesia. A total of the 33 Physalis accessions was analyzed employing 16 SSR markers. AMOVA, UPGMA clustering, and non-parametric ANOVA analyses were applied. The results showed Genetic diversity in this sample showed lower levels (He =0.171), as compared to other studies of Physalis that used different molecular markers. The dendrogram revealed the presence of five groups, the different species belong to different small groups. The two major groups consist of accessions originated from eastern Java and Madura Island, indicating that there is no significant difference between accessions from both areas although there is geographic isolation in the form of the strait. It is consistent with the low population differentiation and high genetic drift. The AMOVA revealed that 96% of the total variation came from the within-population (among accession), reflect that the accessions used in this study have high variation and valuable for plant improvement through breeding programs. It is recommended that future evaluation studies include more accession from minor accessions detected in the sample of this study to better represent the genetic diversity available in this crop.

Abstract. Anggraeni TDA, Waluyo B, Sugiharto AN, Kuswanto. 2022. Genetic diversity analysis among 123 accessions of castor (Ricinus communisL.) using SSR marker and its association to agronomic traits. Biodiversitas 23: 1211-1221. Castor (Ricinus communis L.) breeding program targets to create dwarf-type plants suitable for mechanical harvesting. Characterization of plantsusing morphological and molecular markers can enhance the successful breeding program. This studyaimed to investigate the diversity of castor accessionsusing Simple Sequence Repeat (SSR) markers and find the SSR markers that are significantly associated with the agronomic traits. The castor germplasm collection consisting of 123 accessions from the islands throughout Indonesia, breeding lines, and introducedaccessions displayed a moderate genetic diversity. The germplasm collection showed high variation in plant height, node length average, number of nodes, 100 seed weight, and oil content. The association analysis using GLM (General Linear Model) and MLM (Mixed Linear Model) could detect six associations between SSR marker alleles and agronomic traits. Among the marker alleles, two marker alleles had an overlap association. RcSSR-12_175 had an association with plant height and flowering day, RcSSR-23_113 had an association with node length average and branch number, and RcSSR-4_125 had an association with seed weight/raceme. This finding could provide information on Indonesia’s castor accession status. The linked-trait SSR markers are useful in marker-assisted selection for breeding high yield dwarf type-castor.

Abstract. Rudarmono, Ardiarini NR, Waluyo B, Ashari S. 2022. Interspecific and Intraspecific cross-compatibility of Durio kutejensis and hybrid Durio zibethinus x kutejensis. Biodiversitas 23: 1837-1843. Lai (Durio kutejensis) and Mandong (Durio zibethinus x kutejensis) fruits that have advantages and high consumer preference values. Fruit productivity and development of Lai and Mandong plant varieties are still not optimal. The aim of this study was to analyze the level of incompatibility of interspecific and intraspecific crosses between Lai (D. kutejensis) and Mandong (D. zibethinus x kutejensis hybrid) plants. Artificial crosses were made utilizing flower samples from Mahakam, Kutai, and Batuah types of Lai plants, as well as Mandong varieties of Mandong, employing a scheme of 20 crossings that included a combination of these varieties (12 treatments), as well as each variety from the same flower and tree (8 treatments). The intensity level and incompatibility classification were determined according to Wang's (1963) method, which was based on the number of fruits formed from artificial crosses, and the pollen incompatibility intensity level (IIL) was determined according to the ratio of flowers that produced fruit from the cross to the total number of flowers crossed. The results showed that overall crosses of the same flower (selfing) from three varieties of Lai and one variety of Mandong were incompatible. Lai Mahakam x Lai Batuah crosses yielded 14.28 % harvested fruit, Lai Mahakam x Lai Mahakam crosses yielded 18.75 % harvested fruit, Lai Kutai x Lai Kutai crossings yielded 14.81 % harvested fruit, while a cross of Durian Mandong x Lai Batuah yielded 16.67 % harvested fruit. It shows partially compatible. The complete compatibility value showed the number of harvested fruit ranged from 23.44 to 46.77%, with the most significant being obtained from a Lai Mahakam x Durian Mandong cross. The Mahakam, Kutai, Batuah, and Mandong varieties are compatible with all pollen sources.

Abstract. Supriadi D, Bimantara YM, Zendrato YM, Widaryanto E, Kuswanto K, Waluyo B. 2025. Genotype-by-environment interaction and tolerance of tropical maize under low nitrogen conditions. Biodiversitas 26: 3863-3874. The environment is the main factor affecting the performance of agronomy and the yield of tropical maize. In this context, the development of maize hybrids with low nitrogen (N) tolerance is crucial but challenging since genotype selection is biased toward the existence of Genotypes by Environment Interaction (GEI). Therefore, this research aimed to show the responses as well as determine the tolerance and stability of maize hybrids under low nitrogen environmental conditions in four environments. A total of 10 maize hybrids were analyzed using a randomized complete block design with three replications. The results showed that GEI was significant for most of the observed traits, including grain yield and yield components, as well as physiological traits. The percentage of G × E variance exhibited considerable differences among various traits, with values ranging from 13.68% for stomatal length to 50.00% for the number of ear rows. The low nitrogen environment significantly influenced ear performance and physiological traits, resulting in a lower average grain yield (6.98 t ha-1) compared to normal conditions (10.72 t ha-1), as well as the other traits. G01, G02, and G05 were identified as tolerant hybrids based on the ranking summary of stress tolerance indices. Meanwhile, G01 and G03 were selected as stable hybrids based on stability statistics and Genotype + Genotype × Environment (GGE). G01 (R0211) had the highest yield and remained stable-tolerant in low-nitrogen environments, demonstrating its superiority as a genotype. This study and the above genotypes could be used as genetic material for future maize breeding to develop new varieties that are both high-yielding and stable under low N, especially under tropical regions.
