Abstract

This study aims to compare the resistance of hybrid maize varieties from "PT Cipta Makmur Pertiwi" to downy mildew caused by P. philippinensis and P. maydis species. This research was conducted from May to August 2020 at IP2TP Balitsereal Bontobili, Gowa, South Sulawesi and in July-October 2020 in Kencong Village, Kepung District, Kediri Regency. The experiment was arranged in a group design with 3 replications. Each line, spacing of 70 x 20 cm, population of 120-150 plants. For comparison, the susceptible variety was the Anoman variety and the resistant variety Pertiwi 6. The susceptible and resistant varieties were planted side by side in every 3 lines and varieties tested. The results showed that strain TB 06 (13.60%) was classified as resistant and strain TB04 (35.89%), ADV 777 (26.38%) and ADTR 5123 27.24% was classified as moderately resistant to downy mildew caused by Peronosclerospora species. . Test line TB 06 infected 19.59%, or classified as resistant, in a susceptible comparison (Anoman) the intensity reached 99.30% (very susceptible) and was positively corrected in a resistant comparison (Pertiwi 6) infected 14.58 or resistant to disease downy mildew caused by the species Peronosclerospora maydis. From the results of the study, for the ADTR5123 variety in the Bontobili region, resistance to downy mildew 12.47% to 27.24% was classified as moderately resistant. While the ADTR5123 variety in the Kediri region was resistant to downy mildew from 92.51% to 94.24% classified as very susceptible

Abstract

The Agrotechnology Study Program, Faculty of Agriculture, Kahuripan University of Kediri (UKK) conducted an adaptation test in South Sulawesi which aimed to determine the productivity and agronomic appearance of prospective hybrid corn varieties from breeding compared to varieties that already exist in Indonesian corn centers. The testing activity was carried out at IP2TP Balitsereal, Bontosalama Village, Bajeng District, Gowa Regency, South Sulawesi from August to December 2022. The genetic material used consisted of 7 hybrid corn test hybrids, namely: UKK01, UKK02, UKK03, UKK04, UKK05, UKK06, and UKK07 and 2 comparison varieties, namely NK 7328 and ADV 789. The test was arranged using a Randomized Completed Block Design, 3 replicates. The results of the adaptation test show that the test hybrid with a productivity of 8.74 t/ha – 10.03 t/ha is superior to the comparator variety with a productivity of 11.75 t/ha for NK 7328 and 11.78 t/ha for ADV 789.

Abstract

Salak has the scientific name Salacca zalacca including a low-growing family of palms. This seasonal fruit plant is a type of horticulture that has the potentioal to become an axport commodity in Indonesia. In East Java, especially in Lumajang, Madura and Kediri are areas that produce salak commodities. Morphological identification aims to obtain basic traits so that the appearance or phenotype of each accession can be distinguished quickly and easily, by estimating how much genetic diversity it has. This study aims to determine the morphological characters and to determine the salak kinship of Lumajang, Kediri and Madura. The result of phylogeny analysis of the Salacca zalacca kinship in East Java show that the results of the kinship analysis of the salak in the Lumajang, Kediri and Madura areas formed 2 large groups or cluster. So it can be concluded that the Salacca zalacca originating from the Lumajang, Kediri and Madura areas still come from the same ancestor. This can be seen from the value of kinship distance, the morphological identificaion equation. In addition, environmental factors can also affect the morphology of plants. Sunlight intensity, N and P nutrients can also affect the difference in leaf color
