“…In this case, the spikelets covered by the flag leaf are not pollinated. Cold stress has a more direct effect on spikelet fertility because when it occurs during microsporogenesis, it causes degeneration of microspores, resulting in sterility cold stress [18]. Included in the group of cold tolerant rice genotypes for sowing Date 1 were V5 (87041-TR 990-11-2-1), V6 (88021-TR 1046-2-1-2-1), V13 (89014-TR 1134-2-2-3), V15 (89018-TR 1138-4-2-1), V18 (83025-TR 643-1-1-1-1), V35 (IR 57257-34-1-2-1), V69 (NONG 56), V162 (FANDRAPOTSY 104) and V169 (BOTRYKELY) that had high yields and good cold tolerance traits even after experiencing cold stress at the reproductive stage.…”

Abstract:In the Sahel zone of West Africa that extends from Senegal to Chad, temperatures can vary from less than 15˝C to 25˝C from November to February. These low temperatures affect the growth, development and yield of rice plants, and therefore constitute a major constraint to rice production in the Sahel. In order to identify rice varieties tolerant to cold stress at different developmental stages, a diverse set of 224 rice germplasm was evaluated for yield and yield-related traits in Ndiaye, Senegal, using three different sowing dates. The first sowing date (October 2010), was chosen so as to expose the rice plants to cold stress at the reproductive stage while the rice crop planted at the second sowing date (January 2011) experienced cold stress at the vegetative stage. The third sowing date (July 2011) was the normal planting date for irrigated rice in the Sahel and it served as the control date when the crop does not experience any cold stress throughout its growth cycle. Among the data collected, significant genetic variation was detected and genotype-by-environment interaction was also significant for the traits. At the vegetative stage, cold stress reduced tillering and plant vigor and delayed flowering but increased yield, whereas at the reproductive stage, aside from delaying flowering, cold stress also inhibited panicle exsertion and reduced panicle length, spikelet fertility, grain filling and strongly reduced yields. Principal Component Analysis and correlation analysis using agro-morphological traits helped to identify genotypes that were tolerant to cold stress at either the vegetative or the reproductive stage and the traits associated with high yield under cold stress at each of these stages. Our results can be used to develop cold tolerant rice varieties adapted to double cropping in the Sahelian zone of West Africa.

“…differences in cold tolerance). Many QTLs for cold tolerance in rice have been discovered, and they have been found on most chromosomes (except chromosome 6) using different combinations of parent cultivars; they have been found on chromosome 1 (Takeuchi et al , Andaya and Mackill , Xu et al , Kuroki et al , ), chromosome 2 (Andaya and Mackill ), chromosome 3 (Andaya and Mackill , Dai et al , Suh et al , Mori et al , Shirasawa et al ), chromosome 4 (Saito et al , , , Xu et al ), chromosome 5 (Andaya and Mackill , Xu et al ), chromosome 7 (Takeuchi et al , Xu et al , Suh et al , Zhou et al ), chromosome 8 (Kuroki et al , ), chromosome 9 (Suh et al ), chromosome 10 (Dai et al , Ye et al ), chromosome 11 (Takeuchi et al , Oh et al ) and chromosome 12 (Andaya and Mackill ). The complex nature of cold tolerance mechanisms at a molecular level is suggested by the genome‐wide distribution of these many QTLs.…”

Male sterility induced by low temperatures (LTs) during the reproductive stage is a major constraint for temperate zone rice. To detect physiological quantitative trait loci (QTLs), we modeled genotypic variation in the physiological processes involved in low temperature spikelet sterility on the basis of anther length (AL), a proxy for microspore and pollen grain number per anther. The model accounted for 83% of the genotypic variation in potential AL at normal temperature and the ability to maintain AL at LT. We tested the model on 208 recombinant inbred lines of cold-tolerant 'Tohoku-PL3' (PL3) × cold-sensitive 'Akihikari' (AH) for 2 years. QTLs for spikelet fertility (FRT) at LT were detected on chromosomes 5 (QTL for Cold Tolerance at Reproductive stage, qCTR5) and 12 (qCTR12). qCTR12 was annotated with the ability to maintain AL under LTs. qCTR5 was in a region shared with QTLs for culm length and heading date. Genome-wide expression analysis showed 798 genes differentially expressed in the spikelets between the parents at LTs. Of these, 12 were near qCTR5 and 23 were near qCTR12. Gene expression analysis confirmed two candidate genes for qCTR5 (O-methyltransferase ZRP4, Os05g0515600; beta-1,3-glucanase-like protein, Os05g0535100) and one for qCTR12 (conserved hypothetical protein, Os12g0550600). Nucleotide polymorphisms (21 deletions, 2 insertions and 10 single nucleotide polymorphisms) in PL3 were found near the candidate conserved hypothetical protein (Os12g0550600) and upstream in PL3, but not in AH. Haplotype analysis revealed that this gene came from 'Kuchum'. The combination of mapping physiological QTLs with gene expression analysis can be extended to identify other genes for abiotic stress response in cereals.

“…Molecular marker analysis revealed that 2 cold-tolerant strains carried chromosomal segments of Silewah at the same genomic regions on chromosomes 3, 4 and 11. Single marker analysis in segregating population confirmed that the allele of Silewah on chromosome 3 (qCTB3-Silewah) conferred cold tolerance (Mori et al, 2011). Xu et al (2008) conducted the experiment which involved 1557 BC 5 F 2 plants and their F 3 progenies grown over 2 years and they detected the eight markers which were distributed on chromosomes 1, 4, 5, 10 and 11 that were associated with cold tolerance.…”

Rice is a cold-sensitive plant that has its origin in tropical or subtropical areas and cold damage can cause serious yield losses. Low temperature affects the rice cultivation mainly in two stages of development i.e. seedling and booting. In both of them, cold temperature has harmful effects on crop productivity. Low temperature during the reproductive stage in rice causes degeneration of spikelets, incomplete panicle exsertion and increases spikelet sterility thus reducing grain yield. The most sensitive stage to low temperature is the booting stage. The percentage of fertile spikelet has been used as effective parameters of cold tolerance of rice at booting stage. Low temperature at booting stage causes anther injury, degeneration of young microspores, resulting in high spikelet sterility and reduced rice yield. Understanding molecular mechanism of cold stress in rice became an important step since it will increase the precision in screening in addition to phenotypic evaluation. Cold tolerance in rice is a quantitative trait controlled by multiple genes. Because it is often difficult to directly associate plant phenotypes with the genes responsible for cold tolerance, therefore marker-assisted selection is an effective means of developing coldtolerant cultivars. Dissecting cold stress-mediated physiological changes and understanding their genetic causes will facilitate the breeding of rice for cold tolerance. Research on quantitative trait loci (QTL) related to cold stress at the germination, seedling and reproductive stages that will provide useful information to accelerate progress in breeding programme.
