“…These results were consistent with the previous study that amylose content was positively correlated with setback and consistency viscosity (Juliano et al, 1964, Shu et al 1988, but negatively correlated with peak viscosity and breakdown (Tong et al, 2014). Our study indicates that starch pasting properties could be a useful indicator because these values were different between samples with similar amylose content, and most of rice quality traits and starch pasting properties showed a significant correlation.…”

: This study was conducted to know the variation and relationship of rice grain quality and starch pasting properties by transplanting times. Two early maturing rice cultivars which accounted for the most area of early maturing rice cultivar in Chungnam province were used. The experiment was laid out in a split-plot design with 3 replications. The main plot consisted of three transplanting times viz. early (April 25), ordinary (May 25) and late (June 25) with sub-plots containing two cultivars. According to the transplanting times, most of rice grain quality and starch pasting properties showed significant difference and Joami showed higher grain quality than Unkwang in all transplanting times. Especially, rice grain quality was improved when transplanted late, showing high head rice and glossiness of cooked rice due to the lower mean temperature during grain filling stage. Glossiness of cooked rice was positively correlated with head rice ratio, amylose content and setback value, and negatively correlated with chalky rice ratio and protein content. The highest positive and negative correlation were observed between breakdown value and peak viscosity (r = 0.98**), and breakdown and setback (r = -0.94**), respectively. These results provide some information for rice researchers and producers producing cultivars with an improved quality, suggesting that rice quality is highly influenced by temperature at grain filling stage, and transplanting times is crucial in improving rice quality. In addition, starch pasting properties are useful for determining rice quality because rice grain quality and starch pasting properties are dependent on each other.

“…Gel consistency (GC) enables to indicate the rice texture after cooled. This was consistent with the statement of Juliano et al (1981) [14] that amylose content (AC) is one of the important criteria in rice classification. Medium amylose content is attributed to sticky rice (not too wet or dry), while high amylose is correlated to hard, dry, and firm rice.…”

“…Physical quality of grain and rice was analyzed based on Wibowo et al 2006 [10] but it modified with SNI 01-6128-1999 [11] and IRRI in 1996 [12]. Cooked rice quality was analyzed using AOAC 1984 [13] and Juliano 1985 et al [14].…”

The elite rice has been produced, including iron (Fe) tolerant varieties. To get the appropriate rice lines which superior not only Fe tolerant but also have good grain quality needs to be developed selection system, especially in the use of molecular markers. This study was aimed to develop molecular markers for selection the rice grain quality characters of selected rice lines Fe tolerant. A total of 30 selected Fe tolerant rice lines and 5 parents as control lines were used in this research. Characterization of grain quality were quantitatively using the standard. While for genotyping analysis used 19 molecular markers of STS, SSR, Indel and SNP. This study showed that 14 of 19 markers result polymorphic DNA band (DNA markers). Association analysis of genotype and phenotype showed that 10 of 14 markers were significantly (p < 0.05) related to high quality of rice grain. Among four types of markers used in this study, STS was the most widely associated significantly with four characters of rice quality. The phenotyping analysis showed that the physical grain and palatability quality which obtained from the total mean of 30 rice lines tested tend to nearly with the parent's value as controls lines. The most of these lines were included in the group IV of National Rice Grain Quality Standard (SNI). The amylose content (AC) showed that the texture was varied from firm and dry (high AC) to soft and sticky (low AC). The association results showed that there were significant (p ≤ 0.05) markers related with the biosynthesis starch genes, i.e: sbe1, ss1, ssiia, gpa, pul and s3cl which contributed on the character of rice palatability. These selected significant markers could be useful for screening of other population with Fe tolerant and/ or other desired morpho-agronomical traits in support of rice breeding program in Indonesia.

“…The variation in the protein content of rice grains may primarily be ascribed to cultivar differences, genetic makeup of the cultivars, climatic condition, and nutrient status of the soil as well as the analytical methods used (Baishya et al, 2010). Effects of such factors on protein content of rice was observed by Juliano et al (1964).The highest (4.28 mg/100g) Zn content was found in 'Pakai' and lowest (3.42 mg/100g) in 'Bairing' with an average 3.90 mg/100 g whereas 'Vandana' contained 2.58 mg/100g. The highest Fe content was recorded in 'IRAT-141' (4.18 mg/100g) and the lowest in 'Miren'(3.21 mg/100 g) with an averageof 3.67 mg/100 g as against 'Vandana' (2.67 mg/100g).The Fe content of the cultivars as recorded in the present study was found to be similar with the findings of Borua et al(2004) but higher than the findings of Yodmanee et al (2011).…”

Fourteen pigmented hill rice cultivars along with a non-pigmented one were studied for ascertaining the extent of their nutritional and genetic diversity. Moisture contents of the fourteen pigmented hill rice cultivars ranged from 7.49 to 10.10 % along w.ith the contents (% dry weight) of nutrients viz., crude fat (4.37 -5.27) and crude protein (9.27 -11.42). The corresponding range of values for the contents (mg/100g dry weight) of microminerals Zn and Fe were form 3.42 to 4.28 and from 3.21 to 4.18 respectively. The pigmented germplasm had anthocyanin content (mg cyanidine 3-O glucoside /100g) ranging from 3.58 to 7.86, total phenolic content (mg GAE/100 g)from 67.89 to 89.43, flavonoid content (mg QE/100g)from 57.75 to 78.74 and antioxidant activity from 19.56 to 29.29 %. Analysis of variance indicated that the varietal effect on each of the parameters studied was highly significant. There was significant correlation amongst the different parameters of the rice genotypes analysed. Results of the biochemical screening of these cultivars may lead to selection of promising candidates that can be used for developing improved lines in future breeding programmes.
