Abstract

The potential lines of West Papua local waxy corn has been already obtained in the previous studies, but the yields have not been further tested. In seed certification for the release of varieties from plant breeding results, it is necessary to conduct multilocation tests to obtain stable and superior yields in various locations. The aim of this research is to test the continued yield of potential lines of West Papua's local waxy corn at several areas in West Papua Province. The study was conducted in Prafi and West Manokwari Districts. The method used was an observational method using a Randomized Complete Block Design of 2 factors: Factor 1 was treatment of 7 local corn genotypes and factor 2 was treatment of 2 locations. Each treatment was repeated 3 times. Variables were observed included yield components of the maize genotypes tested. The data obtained were analyzed using ANOVA and if it had a significant effect, further BNJ test was performed at 95% confidence level. The results showed that productivity (seed weight ha-1) of the 7 genotypes tested were: 1) Ranging from 2.72 tons ha-1 (KM-BC3F1) to 7.66 tons ha-1 (AM-BC3F1 ) in the Prafi District, 2) from 3.30 tons ha-1 (AP-BC3F1) to 7.46 tons ha-1 (KL) in the West Manokwari District, and 3) from 3.28 tons ha-1 (KM-BC3F1) to 5.92 tons ha-1 (AM-BC3F1) in the G x L interactions. Genotype AM-BC3F1, AP-BC3F1, and P have higher productivity in Prafi District, on the contrary genotype KM-BC3F1, KP-BC3F1, AL, and KL have higher productivity in West Manokwari District.

Abstract

ABSTRACT: Sweet potato (Ipomoea batatas L.) is one of the world's most important food crops with great potential to be developed in Indonesia. This plant is rich in carotenoids and anthocyanins. Anthocyanin compounds in sweet potatoes function as components of healthy food. The purpose of this study was to identify the morphological diversity of sweet potato accessions, cultivation systems, and utilization of local communities in Wanggar District, Nabire Regency. The method used in this research is descriptive method with direct observation techniques in the field, at 3 villages: namely Wiraska, Wanggar Sari, and Karadiri in the Wanggar District, Nabire Regency. Data on sweet potato diversity were analyzed using cluster analysis with the NTSYS version 2.0 program. The result of this research are: (1) At the research sites in the villages of Wanggar Sari, Wiraska, and Karadiri there were 6 cultivars of sweet potato plants based on local names, namely: Unggu, Mokupudugu, Ueta, Mokupudugu, Nota, and Gelakue genotypes. These 6 cultivars had a diversity of morphological characters, (2) Based on the results of the cluster analysis, there are 2 main clusters that have the lowest similarity in morphological characters (34%), namely Cluster I (Unggu and Gelakue) and Cluster II (Makupudugu, Nota, Ueta, Kilumbi). The genotypes of Ungu and Gelakue in Cluster I have similar morphological characters of 43%, (3) Local communities in the Wanggar District still use traditional sweet potato cultivation systems and techniques that have been used from generation to generation, from land clearing to harvesting, and (4) In addition to being used as food, the plant parts of sweet potatoes are also used based on local wisdom communities as traditional medicines and natural fertilizers.
