Abstract

Breeding of drought tolerant rice has become the main agenda of breeders nevertheless it is crucial in ensuring the capability of this new drought tolerant rice to satisfy customers in terms of physio-chemical properties as well as the grains and cooked rice quality. In this study, ten rice genotypes were evaluated for physiochemical properties and its quality by which eight were drought tolerant pyramided lines (PLs) and the parents, MR219 and MRQ74. All genotypes of had intermediate amylose content (AC) ranging from 20% to 25% except PL-MR219-G1 (low AC - 16%) and MRQ74 (high AC - 27%). All genotypes also had moderate gelatinization temperature (GT), soft gel consistency (GC) and slender grain shape. No significant different results were obtained between PLs and its parent for all attributes in hedonic analysis except for aromatic trait in MRQ74 population. The score of PL-MRQ74-G1 for aromatic trait in sensory analysis was significant different to MRQ74 indicate that this PL is non-aromatic rice. The genotyping analysis confirmed that the gene which control aromatic trait, badh2 was absent in PL-MRQ74-G1 due to recombination during crossing. However, badh2 allele was present in PL-MRQ74-G2 which supported the hedonic analysis where this PL was not significant different to MRQ74 for aromatic trait. In general, PLs were similar to commercial rice (their parent) for physio-chemical properties and quality traits. The new drought tolerant PLs can be commercialized as it satisfies Malaysian customers that favor soft and slender cooked rice besides its short cooking duration.
