Advances in Breeding of High-amylose Indica Hybrid Rice Combinations in Sichuan Province

During 2000-2013, a total of ten high-amylose specific hybrid rice combinations were approved and five combinations for production test were bred in Sichuan Province. In this paper, rice yield, economic traits, quality indicators and rice blast-resistance identification results of these 15 hybrid combinations were described and analyzed. Results show that Chuanxiangyou37 and Tianlongyou540 have relatively high amylose content, good yielding ability, high resistance and appropriate growth period, which are new hybrid rice varieties with organic combination of high amylase content, high gel consistency, high yield, stable yield and wide adaptability. Therefore, Chuanxiangyou37 and Tianlongyou540 are recommended as the main combination for rice production.
