Yield ability and grain quality of upland rice in Sukabumi and Lampung

Efforts to increase rice food production in the future are faced with increasing climate uncertainty due to global climate change. One of the impacts is changes in strains or biotypes of pests and diseases, which are increasingly rapid. To minimize the impact of climate change on national rice production. The purpose of this study was to produce upland rice lines that resistant to blast disease and had good rice quality. The research carried at Lampung and Sukabumi of 2018. A total of 17 lines and three comparison varieties tested using a randomized block design with four replications. Observations made on the agronomic character, yield components and quality of rice. The results showed that the average plant height in the two locations ranged from 90 to 136 cm. The number of productive tillers at two locations it’s the average of 11 panicles. The mean flowering age did not differ from the harvest age between the lines tested at the two locations. The length of panicle lines tested at two locations averaged 25.5 cm. The average weight of 1000 grains at both locations is 26.1 grams. Grain yield in Lampung averaged 4.7 t ha −1 , higher than in Sukabumi 3.6 t ha −1 . Five lines had no significant difference with Limboto both at the Lampung location and in Sukabumi. Among all the lines tested, there are three lines with the medium of chalkiness or LMM size. The results of testing in the greenhouse against blast disease obtained one line resistant to three blast races.
