“…According to our genotyping results, traditional Malaysian rice has shown good resistance to the major diseases, particularly Pulut Hitam 9, which is resistant to all three diseases ( Table 5 ; Figure 2 and Figure 3 ). Because Pulut Hitam 9 is a waxy rice, it can be used as a donor parent for the development of low-amylose or waxy rice with disease resistance [ 3 , 4 , 9 ].…”

“…The present-day rice industry must not only meet increasing demand but also changing consumer demands, with a strong emphasis placed on producing high-quality rice, which significantly impacts both palatability and consumer acceptance. Fragrance (or aroma) is one of the most important grain qualities of rice [ 2 , 3 ]. According to Hu et al [ 2 ], consumers prefer pleasantly fragranced rice, such as Basmati rice, which has had a large market in Asia for decades despite being more expensive than nonaromatic rice.…”

While previous research has demonstrated that multiplex polymerase chain reaction (PCR) can be a cost-effective approach to detect various genes in crops, the availability of multiplex assays to simultaneously screen both grain quality and biotic stress resistance traits in rice (Oryza sativa) is limited. In this work, we report six novel multiplex assays that use a universal protocol to detect major rice grain quality (amylose content and fragrance) and biotic stress (blast, sheath blight, and bacterial leaf blight) traits with amplified products consisting of up to four primer pairs that can be analyzed using a standard agarose-based gel electrophoresis system. Recent studies have suggested that weedy rice has novel sources of disease resistance. However, an intensive screening of weedy biotypes has not been reported in Malaysia. Accordingly, we employed one of the developed multiplex assays to screen reported genes or quantitative trait loci (QTLs) associated with blast, sheath blight, and bacterial leaf blight diseases in 100 weedy rice biotypes collected from five local fields, with phenotyping performed to validate the genotyping results. In conclusion, our universal multiplex protocol is effective for the large-scale genotyping of rice genetic resources, and it can be employed in routine molecular laboratories with limited resources.

“…Xiao et al [26] also broke the deleterious linkage between yield, taste quality, and blast resistance through the identification of several superior alleles for these traits. Therefore, more studies are required to identify and pyramiding the superior alleles for eating quality-related traits, such as Wx and ALK [19].…”

“…Extensive progress has been made in the research on the biological pathway and molecular regulatory network that determine grain quality [7,9,[16][17][18]. Recently, improvement in cooking and eating quality is the primary concern in hybrid rice breeding and cultivation, which is mainly determined by the amylose content, gel consistency, and gelatinization temperature [9,19]. These three parameters are mutually related, because the starch synthesis-related genes regulating these traits form a fine network [18].…”

“…Hence, evaluation of the eating quality is commonly conducted in a descriptive way depending on local preferences [8]. Although significant progress has been made in identifying the genes regulating starch biosynthesis, protein content and composition, grain oil synthesis, and aroma, achieving premium quality rice in a high-yielding background is still a great challenge for rice breeding [19].…”

Coordinating High Yield and Superior Eating Quality of Rice: A Case Study of Hybrid Varieties Derived from Longke638S and Jing4155S

et al. 2022

The planting area of hybrid rice (Oryza sativa L.) has continuously decreased in recent years partially because of the low eating quality. Longke638S and Jing4155S are two elite male sterile lines, which are used for developing many hybrid varieties with large planting areas in China. Here, 21 hybrid rice varieties of an incomplete diallel cross population with Longke638S and Jing4155S as female parents were planted under field conditions for two consecutive years, aiming to investigate the physiological and transcriptomic characteristics that is required for coordinating high yield and superior eating quality. As a result, grain yield ranged from 7.15 to 9.23 t ha−1 in 2019 and from 7.49 to 9.23 t ha−1 in 2020, and a negative relationship was identified between yield and quality-related traits. Hybrid varieties with Longke638S as the female parent (LLY) had higher yield but lower eating quality than those with Jing4155S as the female parent (JLY). The higher yield of LLY over JLY was due to higher biomass production and N uptake as well as higher yield stability across planting years, while their lower grain quality can be mainly ascribed to lower amylose content and alkali spreading value. Male parents significantly affected yield-related traits of LLY and eating quality-related traits of JLY. Candidate genes involved in grain starch biosynthesis were differentially expressed between LLYHZ, JLYHZ, and JLY1212, such as Wx and ALK. Overall, this study examined the relationship between grain yield and eating quality and identified the physiological and molecular traits that limited grain yield or eating quality of LLY and JLY hybrid varieties.
