RESUMEN

<b>Background and Objective:</b> Worldwide, <i>Bactrocera carambolae</i> and <i>Bactrocera dorsalis</i> are important pests in horticultural commodities. Based on the trapping with methyl eugenol attractant, it was found that the intermediate morphology between <i>B. carambolae</i> and <i>B. dorsalis</i>. This study observed the comparative biology and survivability of the interspecific and intraspecific hybrids <i>B. carambolae</i> and <i>B. dorsalis</i>. <b>Materials and Methods:</b> This study was conducted at the Indonesian Center of Forecasting Plant Pest Organisms (BBPOPT) and Plant Pest Laboratory, Faculty of Agriculture, Universitas Padjadjaran, Indonesia. The method is an experimental method with a randomized block design that involves parental fecundity and survival test (four treatments and six replications) and fecundity and fertility tests (eight treatments and four replications). <b>Results:</b> The results showed a bigger reduction in the fecundity of hybrid parents of <i>B. carambolae</i> and <i>B. dorsalis</i> on interspecific rather than an intraspecific hybrid. The longevity of survival and development of eggs and larvae stages hybrid <i>B. carambolae</i> (♂). Moreover, the fecundity of F1 hybrids was increased compared to the hybrid parents and the fertility was in the range of 79.00-96.75%. <b>Conclusion:</b> Interspecific mating of <i>B. carambolae</i> and <i>B. dorsalis</i> have the potential to survive in nature.

RESUMEN

Turmeric (Curcuma longa L.) is widely used as traditional medicine, kitchen spice, and natural dyes in Indonesia. The demand and popularity of this plant is increasing; however, the national supply is still low. Turmeric breeding and crop improvement in Indonesia are needed to boost the national turmeric production. Exploration of turmeric from various areas in Indonesia is a prior step of turmeric breeding. Phenotypic diversity and relationship analysis of an early population can be used as a basis for consideration in plant development and breeding programs. The purpose of this study was to estimate phenotypic diversity and relationship of local turmeric accessions from Indonesia. Raw data analysis was conducted after standardization using Principal Component Analysis (PCA) and Hierarchical Clustering Analysis (HCA) to determine phenotypic diversity and relationship among the newly collected genetic resources. The data in this article showed broad phenotypic diversity with plant height, number of shoots, number of leaves on main shoot, petiole length, lamina length, lamina width, number of mother rhizome, total rhizome weight, weight per shoot, pseudostem habit, leaf margin, and rhizome habit as distinguishing traits among the collection. PCA also resulted cumulative variation percentage of 70.73%. In addition, HCA resulted two main groups with the Euclidean range of 0.31-2.97.
