Somatic embryogenesis is a unique process in plants and has considerable interest for biotechnological application. According to a 2004 study (Zhu et al. Cd translocation from sheath to grain occurred along with sugar transfer in the indica cultivars. Cultivated rice consists of two subspecies: Indica and Japonica. japonica/indica hybrid rice was higher than that of japonica rice by 75.6% at N0, 57.2% at N150, 41.1% at N225, 38.3% at N300, and 45.8% at N375. Long Grain Rice- This rice has milled grains that are at least three to four times as long as they are wide. -quality traits also showed distinct Eating distributions within subpopulations (Figure 1B). and . Japonica Rice. ABSTRACT. Th… Right after Japonica comes the second major Asian rice variety, Indica rice. … Using an F(2) population from a cross between the indica cultivar 93-11 and B14, we mapped the BPH12 gene to a 1.9-cM region on … They are usually available in late fall and winter. RN, RL, and MRL had differences at the significant level of p < 0.05 in the two subpopulations, while the difference of RGA between the two subpopulations … Japonica rice grains are also harder than those of Indica rice. For the relationship between GY and PN (GY-PN), a negative association was found for the II (r = -0.17, P < 0.001) and IH (r = -0.32, P < 0.001), but a positive association was found for the JI (r = 0.27, P < 0.001) and JH (r = 0.33, P < 0.001; Figure 2A). Japonica cultivars generally showed higher NPQ capacities than Indica cultivars when we measured a rice core collection. Right after Japonica comes the second major Asian rice variety, Indica rice. Subpopulation differences are well known in , especially between subspecies . There were clear, significant differences between japonica rice and indica rice soils at each soil layers. The percentage of indica varieties m… 1. In Japan, generally, rice should be consumed in 2 months in winter, 1 month in spring/fall, and 2 weeks in summer. Although japonica rice and indica rice are the main food in China, people’s evaluation of them has changed several times in the past decades. Across the three planting years, the average grain yield of japonica/indica hybrid rice was higher than that of japonica rice by 75.6% at N0, 57.2% at N150, 41.1% at N225, 38.3% at N300, and 45.8% at … The Cd content of the indica cultivar grain was 1.84-4.14 times higher than that of the japonica cultivars (P < 0.05). 65 No. In the present study, transcriptomic analysis was performed to illustrate the different reactions of Indica and Japonica rice to Al toxicity. Many studies have shown genotypic differences in Cadmium (Cd) accumulation among rice cultivars, and concentrations in shoots and grains are generally higher in indica rice cultivars than in japonica rice cultivars, but the mechanism remains unknown. 2012). Japonica . This species is the oldest of the listed and characterized by long and almost transparent grains. Indica and japonica are two main subspecies of Asian cultivated rice (Oryza sativa L.) that differ clearly in morphological and agronomic traits, in physiological and biochemical characteristics and in their genomic structure. Generally, japonica rice varieties are more tolerant to low temperatures than varieties of indica rice. Compare to japonica, indica rice has been less responsive to in vitro culture. These results suggest a high level of genetic differentiation between indica and japonica rice. The effect of soluble starch synthase I (SSI) on differences of amylopectin structure between the indica and japonica rice varieties was investigated. Umemoto T, Yano M, Satoh H, Shomura A, Nakamura Y (2002) Mapping of a gene responsible for the difference in amylopectin structure between japonica-type and indica-type rice varieties. Glutinous rice is also divided into japonica rice and indica rice, but the overall taste is not different, they can be used to make sticky food. Japonica is a group of rice varieties from northern and eastern China grown extensively in some areas of the world. In this study, IR36 and Weiguo are indica and japonica rice varieties, respectively. It is found in the cooler zones of the subtropics and in the temperate zones. However, the proteins and genes responsible for these differences remain poorly … 1. and . The most popular are Indica, Javanica and Japonica. The F\1\ hybrids between varieties belonging to the latter two types, however, have normal F\1\ fertility (Morinaga 1958). Relationship between grain yield and quality in rice Breeding Science Vol. There was an obvious difference in SSR allelic diversity between indica and japonica rice. The differences in quality traits between indica and japonica. Rice can be divided into several species. We used Illumina Hiseq 2000 sequencing platform for comparative transcriptome analysis between two rice subspecies at six different … In the past 15 years, grain quality in japonica rice and indica hybrid rice have improved, while there have been limited improvements in indica inbred rice—the head rice rate has increased, but the chalky rice rate and amylose content have decreased. Due to its starch composition, it is sepa… In this study, we cloned a quantitative trait locus … One of the two rice PsbS … Japonica rice is also stickier due to the higher content of amylopectin, whereas indica rice starch consists of less amylopectin and more amylose. in rice breeding, if the mechanism of Al-tolerance between Indica and Japonica could be proven to be different. A recombinant inbred line (RIL) population of F 8 and F 9 generations derived from a cross between a typical indica rice (Qishanzhan) and a typical japonica rice (Akihikari) was used to study the difference between morphological differentiation based on phenotype characters and genetic differentiation using indica and japonica … These results indicate the presence of rich genomic diversity at the SNP level among the 353 accessions.
