Background: Young ricegrass (Oryza sativa L.) can be introduced as one of functional food product since sprouts have been much interested in this era due to their high nutritive values. Bio-fortification of selenium is one strategy to enhance plant bioactivity. However, the level of selenium used is varied among species of plants, hence, the proper level needs to be explored.Objective: To investigate the influence of selenium bio-fortification on nutritional compositions, bioactive compounds content and anti-oxidative properties of young ricegrass.Methods: Sodium selenite ranging 0, 10, 20, 30 and 40 mg Se/L has been hydroponically bio-fortified into ricegrass then grown for 8 d and investigated the changes of growth characteristics, selenium content, accumulation of bioactive compounds and anti-oxidative properties.Results:  Results revealed that selenium bio-fortified exogenously increased the accumulation of selenium in ricegrass by 529% at 40 mg Se/L treatment without negatively changes in leaves biomass at the day of harvesting. However, root part weight slightly decreased when increased selenium level. Selenium at concentration of 10 and 20 mg Se/L can stimulate the production of phenolic compounds and antioxidant activities in young ricegrass as measured by DPPH, ABTS, FRAP and chelating assay. Conversely, higher level of selenium fortification reduced the accumulation of phenolics in ricegrass may due to pro-oxidant expression.Conclusion: Selenium bio-fortification can be used as a useful technique to improve quality of ricegrass plantation. 10 mg Se/L treatment was an ideal to trigger the synthesis of phenolics which exhibited high antioxidant activities. While, 40 mg Se/L treatment was ultimate for the production of Se plant foods.Keywords: Antioxidant activities; Bio-fortification; Ricegrass; Selenium

Line × tester analysis involving seven early maturing lines and four high yielding testers, made to produce 28 F1s hybrids. The F1 data revealed that both additive and non-additive gene were important in controlling yield contribution in Indica rice. Variances were significant for GCA and SCA effects for all the characters indicating the significance of both additive and non-additive genes. There was high proportion of non-additive genes for the expression of different traits. Cultivars Anjali, MTU-7029 and BPT-5204 were identified as best general combiners for yield and yield traits among the parents. The most promising specific combiners for grain yield and its contributing traits were Govind × HUR 105, NDR 97 × HUR 4-3, Anjali × HUR 4-3, NDR 97 × MTU 7029, Vandana × BPT 5204, Shanthi × HUR 105, Anjali × MTU 7029 and Shanthi × BPT 5204.

Characterization and variability analysis is important for the improvement of crop plant. This study aimed to evaluate the morphological and molecular variation of exotic early maturing rice (Oryza sativa L.) lines. A total of 32 exotic rice lines collected from different locations were genotyped and clustered using selected SSR markers. Based on morphological dendrogram, the lines were grouped into three clusters viz.I, II and III. Cluster I, cluster II and cluster III had 12, 11, 9 lines respectively. The results showed that the varieties were closely related belonging to the same cluster. DNA Markers namely Simple Sequence Repeats (SSR) is a useful tool for assessing genetic variations and resolving cultivar identities. Positive correlations were found between gene diversity, number of allele, the allele size range and the maximum number of repeats. Among the primers used RM147 identified more number of alleles and average PIC was 0.88. The UPGMA dendrogram based on Nei’s (1972) genetic distance grouped the 32 rice lines into three major clusters. This result indicates that the line which formed grouped together, they are less diverse. A significant level of polymorphism based on morphological and molecular levels was observed. Being grouped into three clusters C1-4-11-7P-2P-1P and IR 79201-49-1-1-1 could be utilized as potential parents for the improvement of yield in early maturing rice lines.
