Summary

Cowpea is one of the crops that have a lot of potential to be utilized as raw food resource in the Southwest Maluku district. The objective of this study was to evaluate local cowpea cultivars from Southwest Maluku under different locations based on morphological characters. The research was conducted in Ambon and Bogor using randomized complete block design (RCBD) with three replications. As many as seven local cultivars and three cultivars from ILETRI were evaluated. Observations were conducted on 18 morphological characters. The results showed that morphological characters were significantly affected by cultivars on each location. In general: KM3, KM4, and KM6 cultivars have the highest value in some morphology characters. Correlation analysis showed a significant correlation between the number of nodes with number of leaves followed by seed number plant-1 with seed weight plant-1 and loci number pod-1 with seed number pod-1 . Principal component analysis showed that there were nine principal components and clustering in two clusters. The local cultivars have the highest genetic potential in this study and could be selected as plant materials in future plant breeding program.

Key words: Different environments, local cowpea, Southwest Maluku, morphological characters

Key findings: Cowpea cultivar KM3 was the best genotype at both locations i.e., Ambon and Bogor, Indonesia. It also showed similar stability in some characters and almost equal with cultivars from ILETRI in these locations.

Summary

Jackfruit (Artocarpus heterophyllus Lam.) is one of the most widely cultivated fruit in Indonesia. The Faculty of Forestry, Gadjah Mada Universtity, Indonesia has 11 provenances where jackfruitis widely grown in Indonesia. The aim of this study was to assessed variation injackfruit based on molecular marker RAPD (Random Amplified Polymorphic DNA). Seven RAPD primers namely A-13, A-27, B-4, H-15, L-1, OPB-1, and OPD-19 generated 70 DNA bands, of which 40 were polymorphic. In this study H-15 primers produced more polymorphic fragments than the other six primers and had the highest percentage of polymorphic fragments, namely 91.7%. Similarity matrix was calculated using coefficient of Jaccard. Unweighted Pair Group Method Using Arithmetic Mean (UPGMA) cluster analysis was performedto develop a dendogram. This data analysis was performed by NTSYS software ver. 2.1. In the present studies, jackfruit tress accessions from the eleven provenances were divided into two clusters with similarity coefficient ranging from 63.33 to 85.71%, provenance of East Java and West Java were the most closely similar (85.71%) based on molecular characters.

Key words: Jackfruit, molecular characters, genetic diversity, RAPD

Key findings: Detection of genetic differences and relationship between jackfruit from 11 provenances of Indonesia for sustainable cultivation and for conservation of plant genetic resources.
