Uji Daya Hasil Galur-galur Padi Sawah (Oryza sativa) Asal IRRI

Abstract

To support the increase of rice productivity in Indonesia can be done by using improved rice genotypes obtained from IRRI. The genotypes should have high yield, short growth duration, and resistant to pests and diseases. These lines need to be evaluated in the field. The experiment was conducted to evaluate the yield of some lowland rice lines introduced from IRRI at Balai Besar Penelitian Tanaman Padi Experimental Field, Bogor in November 2013 - April 2014. Experiment used Randomized Complete Blocked Design with single factor and three replications. The factor was lines consisting of lowland rice lines introduced from IRRI, i.e. IR83821-16-2-3-2, IR83821-99-2-2-2, IR84046-10-1-3-2, IR81493-B-B-B-6-B-2-1-2, IR82806-98-3-2-2-2-1, IR83840-90-3-2-1, IR85640-114-2-1-3, IR84778-53-1-2-2-1, IR85627-46-1-2-3, IR80376-12-1-2-3-3, IR78119-24-1-2-2-2, IR10L-130, IR10L-133, IR10L-152, IR10L-135, IR10L-155, and IR10L-139 as well as three national varieties (Inpari 13, Inpari 18 and Ciherang) as checks. The result showed that lines which had the highest productivity was IR83821-99-2-2-2 (3.13 tonnes ha-1), while the line which had the lowest productivity is IR10L-135 (0.84 tonnes ha-1). IR83821-99-2-2-2 line showed higher productivity than the check varieties Inpari 13 and Inpari 18 and was similar to Ciherang.
