“…Evidently, the group B including the most superior rice accessions under low temperature conditions. these results are in agreement with the previous results which reported that Japonica type accessions are more cold tolerance than Indica type (Renata et al, 2010;Sanghera et al, 2011 andSuh et al, 2013). Due to the useful breeding programs are depending on modern and adapted knowledge of genetic diversity among varieties to utilize the available genetic resources to create new genotypes, morphological markers reflect not only the genetic contribution of the genotypes but also the interaction of the genotype with environment in which it is revealed (Thenmozhi and Rajasekaran, 2013).…”

B REEDING rice for cold tolerance is one of the important ways for climate change facing, which attacks a large amount of the cultivated areas all over the world countries. This study was perfomed at Sakha Agricultural Research Station during two rice growing seasons 2015 and 2016 to evaluate some rice accessions which belong to different rice types for the ability of cold tolerance in seedling stage at early growing season under Egyptian conditions. The 40 rice accessions used in this study were evaluated at two early dates of sowing 1 st March and 1 st April as a cold condition, in addition to control sowing date at 1 st May. Twenty six SSR markers related to cold tolerance at seedling stage were used in order to determine the genetic diversity and polymorphism among the studied genotypes. Low temperature degree condition significantly decreased the mean values of the all studied traits for all accessions compared with the control condition. Significant differences were observed among the studied genotypes under both different growing conditions. Japonica varieties are found to be more tolerant than Indica varieties. SSR markers RM265, RM324, RM163 and RM270 showed highly polymorphism among the studied rice accessions and more over differentiate them to different groups based on their ability for cold tolerance. Giza 177, Sakha 102 and Sakha 104 out of the Egyptian rice genotypes showed a good performance at low temperature degrees condition in early growing season. The genotypes CT6749-36-7-2-M-M, Milyang 80, PSRM1-17-4B-13, Ryong Sung 25 can be used as a donor for cold tolerance in rice breeding program.

“…Minimum temperatures during the rainy season ranged from 18˝C to 25˝C while maximum temperatures ranged from 30˝C to 40˝C. (Avangard and Mustaqillik) and Korea (Jinbu) showed high cold tolerance under cold-water and greenhouse conditions showing 71% to 79% spikelet fertility [15,16]. Based on the hypothesis that the sowing date does not have any effect on the varieties, the objectives of this research were to identify cold tolerant rice genotypes that are adapted to the Sahel zone of West Africa and the agro-morphological traits associated with this adaptation.…”

“…According to Dingkuhn and Miézan [14], temperatures below 18˝C can induce up to 50% sterility and this can reach up 100% at 10˝C in very sensitive varieties. In a study of reproductive stage cold tolerance conducted on 23 elite rice cultivars from eight countries, only accessions from Uzbekistan (Avangard and Mustaqillik) and Korea (Jinbu) showed high cold tolerance under cold-water and greenhouse conditions showing 71% to 79% spikelet fertility [15,16].…”

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.

“…Five SSR markers were associated with spikelet fertility under a cool environment greenhouse on chromosomes 8, 9, 10, and 12. They conclude that SSR marker associated to cold tolerance may also be useful as selection markers in indica/ japonica cross combination to improve cold tolerance (Suh et al, 2013). Cconstructed a linkage map with 135 restriction fragment length polymorphism (RFLP) markers and 34 random amplified polymorphic DNA (RAPD) markers using 212 doubled-haploid lines (DHLs) to identify the chromosomal region controlling cool temperature tolerance (CT) at booting stage of rice.…”

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.
