Abstract

ABSTRACTSouth Sulawesi is known as one of national rice production centers. However, average productivity of rice varieties planted in that area (4.43 ton ha-1) is lower than those of rice productivity in Java (5.25 ton ha-1). The aims of this research were to evaluate agronomic characters and adaptation of 7 dihaploid mutant advanced lines of new plant type (DH-NPT) of rice at several locations in South Sulawesi. The research was conducted in 2012 at Maros, Gowa, Barru, and Pangkep. The experiments were conducted in randomized complete block design with 3 replications nested in locations. Treatment consisted of 7 DH-NPT of rice, i.e., BIO-MF115, BIO-MF116, BIO-MF125, BIO-MF130, BIO-MF133, BIO-MF151, BIO-MF153, and control varieties i.e., Fatmawati, Ciherang, and Inpari13. The results indicated that in general the lines had medium height (102.77-110.23 cm), moderate productive tiller (9-16 tiller per hill), moderate days to flower (50%), i.e., 73-76 days after sowing (DAS), earlier days to harvest (103-110 DAS), moderate panicle length (28.35-29.31 cm), large number of grain per panicle (> 250 grains) with moderate panicle fertility (63-70%), moderate 1,000 grain weight, i.e., 26.51-27.75 g, and high yield (7.51-8.09 ton ha-1). Four lines, i.e., BIO-MF116, BIO-MF130, BIO-MF151, and BIO-MF153 were stable and had wide adaptability. Other lines, i.e., BIO-MF125 and BIO-MF133 were sensitive to environmental changes, therefore they were classified as specifically adapted to favorable environment; while BIO-MF115 was not sensitive to environmental changes, and therefore it was adapted to non-favorable environment.Keywords: adaptation, agronomic characters, rice mutant
