“…Agronomic characters in rice plants have a correlation between one character and another. These correlations generally support an increase in production but can also affect a decrease in production [10]. So it is very important to know in the selection of assembled plants.…”

Many high-yielding varieties of rice have been released, but generally lack good quality. This study aimed to examine the agronomic performance of several new plant types of black F3 rice lines at two medium altitude. The research was carried out on rice fields in Tallunglipu District, North Toraja Regency with an altitude of 850 m above sea level. This research took place from May 2020 to November 2022. This study used the Single Seed Descend selection method which was arranged in randomized block design pattern at each location. The genetic material tested consisted of 30 F3 lines resulting from two combinations of crosses between Toraja local black rice, each of which was crossed with a national superior variety and 3 comparison varieties, namely Pare Ambo, Pare Lallodo and Inpari 4 which were repeated 3 times. The observational data were analyzed for variance and if there was a significant effect, then the Honestly Significant Difference was 5% and the value of closeness between characters was tested for correlation and weighted analysis (WINDEX) was performed to select the strains. The results showed that the character had a close correlation with productivity, namely the character of the weight of pithy grain per clump, the maximum number of tillers and the number of pithy grain per panicle. The lines with the best productivity were F3UKIT104-2-194 (5.7 tons/ha) and F3UKIT104-2-197 (5.4 tons/ha). The selected strains based on Windex selection are UKIT104-2-197, UKIT 104-2-194, UKIT 104-2-298, UKIT 104-2-089, UKIT 104-2-127, UKIT-101-2-131, UKIT-101-2-218, UKIT 104-2-003, UKIT 104-2-148, UKIT-101-2-002, UKIT-101-2-003, UKIT-104-2-046, UKIT 104-2-064, and UKIT 104-2-001.
