“…Therefore, as indicated by the recent scientific literature, MAS can provide the best results when combined with other approaches in breeding programs, depending on the genetic control of the target trait. As an example, it has been applied to hybrids production in rice, in which selection for resistance genes is integrated with selection for hybrid genes related to male sterility [ 111 , 112 , 113 ]. In particular, Kim et al [ 114 ] described a large breeding program in which hybrid rice lines highly resistant to diseases were selected based on three major hybrid genes, six genes for resistance to bacterial blight, four genes for resistance to blast, and other two genes for resistance to brown planthopper and tungrovirus.…”

Plant diseases are responsible for substantial crop losses each year and affect food security and agricultural sustainability. The improvement of crop resistance to pathogens through breeding represents an environmentally sound method for managing disease and minimizing these losses. The challenge is to breed varieties with a stable and broad-spectrum resistance. Different approaches, from markers to recent genomic and ‘post-genomic era’ technologies, will be reviewed in order to contribute to a better understanding of the complexity of host–pathogen interactions and genes, including those with small phenotypic effects and mechanisms that underlie resistance. An efficient combination of these approaches is herein proposed as the basis to develop a successful breeding strategy to obtain resistant crop varieties that yield higher in increasing disease scenarios.

“…Rice blast, bacterial blight (BB), brown planthopper (BPH), gall midge (GM) and brown spot (BS) are major biotic constraints in rice. More than 100 major genes and over 350 QTLs for blast resistance (Chen et al ., 2020); more than 44 (dominant and recessive) genes for BB resistance (Kim and Reinke, 2019), more than 11 genes and several QTLs for GM resistance (Zhou et al ., 2020), 31 genes and number of QTLs for BPH resistance (Chen et al ., 2020), and 12 QTLs for BS resistance (Mizobuchi et al ., 2016) are reported. Major QTLs/genes for biotic and abiotic stress and their donors to be used in the DDSR breeding programme are mentioned in Table 1.…”

Rice is a staple food for half of the world's population. Changing climatic conditions, water and labour scarcity are the major challenges that shall limit future rice production. Dry direct-seeded rice (DDSR) is emerging as an efficient, resources conserving, mechanized, climate smart and economically viable strategy to be adopted as an alternative to puddled transplanted rice (TPR) with the potential to address the problem of labour-water shortages and ensure sustainable rice cultivation. Despite these benefits, several constraints obstruct the adoption of DDSR. In principle, the plant type for DDSR should be different from one for TPR, which could be achieved by developing rice varieties that combine the traits of upland and lowland varieties. In this context, recent advances in precise phenotyping and NGS-based trait mapping led to identification of promising donors and QTLs/genes for DDSR favourable traits to be employed in genomic breeding. This review discusses the important traits influencing DDSR, research studies to clarify the need for breeding DDSR-specific varieties to achieve enhanced grain yield, climate resilience and nutrition demand. We anticipate that in the coming years, genomic breeding for developing DDSR-specific varieties would be a regular practice and might be further strengthened by combining superior haplotypes regulating important DDSR traits by haplotypebased breeding.

“…Over time, the tremendous progress in the form of hybrid-breeding technology greatly benefited agriculture by HR with high yield and better tolerance against stressors (e.g., biotic stresses as the diseases, pests, and pathogen infestation and abiotic stresses as the drought, heat, salt, etc.) as compared to the inbred lines/varieties [ 4 , 19 , 20 , 21 ]. Rice is a self-pollinated cereal crop; its male fertility (MF, described as the release of the workable gametes or functional pollens that can fertilize female gametes) control demands the male sterility system to generate HR lines/varieties.…”

“…However, the decrease in HR yield has been examined due to abiotic and/or biotic factors like increasing temperature, rice blast, etc. [ 20 , 37 , 38 , 39 ]. To tackle this problem, green-super HR-technology has been developed that boosted 20% more grain yield per hectare as compared to HR lines in China [ 8 , 38 , 40 ].…”

“…These merits significantly favor the acceptability and multiplication of the two-line HR genetic manipulation across the globe. Furthermore, it has great potential for improvement in yield, quality, and resistance against stressors in HR [ 20 , 44 ]. Recent statistics released by the National Rice Data Centre showed there were cultivated 73 and 40 varieties/types of the three-line HR and two-line HR, respectively, during 2009 to 2019 and only two-line HR accounts for 53% [ 45 ].…”

The significance of the climate change may involve enhancement of plant growth as well as utilization of the environmental alterations in male fertility (MF) regulation via male sterility (MS) systems. We described that MS systems provide a fundamental platform for improvement in agriculture production and have been explicated for creating bulk germplasm of the two-line hybrids (EGMS) in rice as compared to the three-line, to gain production sustainability and exploit its immense potential. Environmental alterations such as photoperiod and/or temperature and humidity regulate MS in EGMS lines via genetic and epigenetic changes, regulation of the noncoding RNAs, and RNA-metabolism including the transcriptional factors (TFs) implication. Herein, this article enlightens a deep understanding of the molecular control of MF in EGMS lines and exploring the regulatory driving forces that function efficiently during plant adaption under a changing environment. We highlighted a possible solution in obtaining more stable hybrids through apomixis (single-line system) for seed production.
