Abstract

The availability of drought-tolerant maize inbred materials are useful to develop a hybrid or synthetic drought tolerant maize varieties. This research was aimed to select drought tolerant and determine secondary traits for selection of inbred maize. Selection of 31 maize inbred lines was conducted in nested experimental design in which the replicate was nested into the drought stress selection condition and normal irrigation. Drought stress treatment was applied during flowering to milk phase. In the normal irrigation condition the water was supplied every 10 days. The results showed that the medium tolerant to tolerant to drought stress inbred lines were 1044-30, DTPYC9-F46-3-9-1-1-B, CML161 / NEI9008, DTPYC9-F46-1-2-1-2- B, and Mr14. The yield declined of tolerant/medium tolerant inbred lines of about 17.0-38.3% was lower than sensitive inbred lines of about 42.8-70.7% under stress condition. The tolerant/medium tolerant inbred lines can be used for developing drought tolerant or synthetic varieties. The secondary traits effective for selection of drought tolerant inbred lines were shelling percentage, leaf chlorophyll, leaf rolling scores, number of tassel, the female flowering dates, and anthesis silking interval (ASI). The traits were more effected by genetic factors than the environmental factors and correlated to yield under drought stress conditions.Keywords: anthesis silking interval, environmental condition, inbred lines, tassel number, yield

Abstract

This study aims to describe the practice of concubinage during the Dutch East Indies as represented in Pramoedya Ananta Toer's novel Bumi Manusia. The study uses a qualitative approach with a descriptive-analytical method. The research data consists of primary data in the form of the novel text Bumi Manusia and secondary data obtained from books, scientific articles, and relevant historical sources. The data collection technique was carried out through literature study, while data analysis was carried out by carefully reading, classifying, and interpreting the data according to the focus of the study. This study focuses on three main issues: the practice of concubinage, marriage without legal status, and the sociocultural impact of this practice. The results show that the practice of concubinage in Bumi Manusia involves an unequal power relationship between European men and indigenous women. Concubinage gave rise to a form of marriage without legal recognition, while also giving rise to sociocultural impacts in the form of changes in the behavior of concubines, social stigma from society, and issues of the legal status of children resulting from concubinage
