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

Maize is a cereal crop essential to fulfill the need for food and support global food security programs. Maize hybrid varieties play a very significant role in increasing maize production. Objectives of the research were to obtain a tester, which is consistent in identifying inbred lines with a high specific combining ability, and to obtain prospective crossed-hybrids that have the potential assembling to be maize hybrid varieties. The grain yield showed that the specific combining ability values ranged from -3682.2 to 5251.7. Crosses that have high and positive specific combining ability included lines of JG-11, JG-18, JG-34, JG-01, JG-40, JG-B0, JG-19, and JG-02 with a tester of JG-T00; lines of JG-20, JG-01, JG-03, JG-42, JG-02, JG-46, and tester of JG-T14; lines of JG-24, JG-08, JG-23, JG-26, JG-21, JG-07, and JG-06 with a tester of JG-T15; lines of JG-38, JG-40, JG-35, JG-36, JG-01, JG-51, JG-17, JG-B0, and JG-08 with tester of JG-T22; and lines of JG-07, JG-01, JG-26, JG-24, and JG-18 with tester of JG-T37. There were combinations of 9 crosses between inbred lines and the best testers, including JG-06XJG-T15, JG-51XJG-T22, JG-49XJG-T22, JG-B0XJG-T22, JG-35XJG-T22, JG-38XJG-T22, JG-17XJG-T22, JG-36XJG-T22, and JG-49XJG-37, which are potential as prospective maize hybrids that have high productivity.

Abstract

One of the strategic steps that must be taken to maintain a steady increase in maize production and distribution in Indonesia is to provide high-yielding varieties that are resistant to biotic and abiotic stresses, and have wide adaptation in various ecosystems. The aim of this research is to produce and release adaptive hybrid maize varieties with high productivity. Testing for leaf rust disease resistance (Puccinia polysora) was conducted in a randomized group design, with 3 replications. The genetic material used was the same as the adaptation test material in the form of 8 test hybrids namely BPN2301, BPN2302, BPN2303, BPN2304, BPN2305, BPN2306, BPN2307, BPN2308, and 2 comparison varieties namely NK6172 and BISI 18. The leaf rust disease resistant check variety used the Pertiwi 6 variety, while the susceptible check used the Pulut URI 1 variety. The results obtained can conclude that the results of the resistance test of 8 hybrid corns, namely Pulut URI 1 variety is very susceptible to leaf rust disease, BPN2303 and BISI 18 are classified as susceptible to leaf rust disease, while other varieties are somewhat resistant to leaf rust disease.
