Modified ratoon salibu is a technique of increasing crop index and production of rice. This research was aimed to knew to obtain information on some varieties appropriate to modified ratoon salibu. The experiment was conducted from April 2017 to March 2018 at Farmers Field of Tanah Datar District of West Sumatra. The investigation was arranged in a randomized complete block design (RCBD) with 14 treatments and three replications. The treatment consists of 14 varieties, i.e., Hipa 8, Hipa 18, Hipa 19, Hipa Jatim 2, Inpari 6, Inpari 10, Inpari 19, Inpari 43, Ketan Ciasem, Ketan Grendel, Kebo, Cisokan, Batang Piaman, and Ciherang. The result showed that the hybrid rice variety more tiller than the inbred and local variety. Batang Piaman variety was the tallest variety on modified ratoon salibu. Some types were appropriate on modified ratoon salibu until salibu two and yield same with Batang Piaman, i.e., Inpari 6, Inpari 10, Inpari 19, Inpari 43, Ketan Ciasem, and Cisokan. Percentage of the ratooning ability of rice variety 12,71% to 80,20 %.
