“…According to the report titled ''The State of Food Security and Nutrition in the World'' jointly published by the United Nations Food and Agriculture Organization (FAO), World Food Programme (WFP), International Fund for Agricultural Development (IFAD), United Nations Children's Fund (UNICEF) and World Health Organization (WHO), it was estimated that more than 815 million people (11% of the global population) would be undernourished in 2017 (World Health Organization, 2018). Over the past few decades, rice has been identified as one of flowering plants best suited to combat global hunger and undernutrition (Kamara & Renzaho, 2014;Nassirou & He, 2011;Nwanze et al, 2006). Previous studies highlight the importance of rice as a major source of numerous nutrients such as amino acids, protein, fat, dietary fibre, iron, thiamin, riboflavin, niacin and vitamin E (tocopherol) (Kennedy & Burlingame, 2003;Wu et al, 2002;Zhai et al, 2001).…”

Over the past few decades, several techniques have been applied to identify the geographical origins of rice products. In this study, the chemical characterization of polycyclic aromatic hydrocarbons (PAHs) was carefully conducted by analysing PAHs in rice samples collected from private sector planting areas located in Bali and Yogyakarta, Indonesia (i.e. ID; n = 20), west sides of Malaysia (i.e. MY; n = 20), Mandalay, Legend, Myingyan, Myanmar (i.e. MM; n = 20), northern parts of Lao PDR (i.e. LA; n = 20), central parts of Cambodia (i.e. KH; n = 20), northern parts of Vietnam (i.e. VN; n = 20), and Thailand (i.e. TH; n = 22). Percentage contributions show the exceedingly high abundance of 5-6 ring PAH congeners in rice samples collected from Indonesia,

“…Rice belongs to the genus Oryza in the grass family Gramineae. There are more than 20 species in the genus, of which only two are cultivated: Oryza sativa, domesticated in the humid tropics of South and Southeast to East Asia, and Oryza glaberrima, domesticated in the Niger basin in Africa [1]. The cultivated species are diploid (2n=24), whereas among the 22 wild species there are both diploids and tetraploids [2].…”

“…New Rice of Africa (NERICA) is a new rice variety in Bangladesh which was introduced in 2009 from Uganda. The rice variety NERICA was developed by Dr. Monty Patrick Jones and his collogues in 1994, at the M'bé research center of Africa Rice Center (WARDA) by crossing (using embryo rescue) between Oryza sativa L. (WAB56-104) and Oryza glaberrima (CG14) [1,3]. NERICA is a rice for Africa and adapted to upland condition in Uganda.…”

New Rice of Africa (NERICA) is drought tolerant and early maturing inter specific rice variety which was introduced in Bangladesh from Uganda in 2009. But the field record of NERICA was not very promising. In order to develop NERICA varieties suitable for agro-climatic conditions of Bangladesh different variations in yield contributing characters are required.In the experiment, physical mutagen treated (250, 300 and 350 Gy Gamma-rays) 18 NERICA mutant lines were selected from M4 to M5 generations along with 3 parents (NERICA-1, NERICA-4, NERICA-10) for morphological and molecular evaluation in orderto identify desired mutant linesusing 12 yield attributing characters and 3 simple sequence repeat (SSR) markers. We also estimated heritability, genetic advance and correlation among the studied morphological traits to identify besttraits based on which further selection could be made. Pearson’s correlation co-efficient of 12 morphological traits indicated that yield per plant had significant positive correlation with the number of tiller, number of effective tiller, panicle length, number of filled grainsper panicle and 1000 grain weight but negative correlation with Plant height and days to maturity. Broad sense heritability ( ) ranged from 71% to 99% while genetic advances in percent mean (GA%) varied from 10% to 60%. Yield per plant, unfilled grains per panicle, number of total tiller, number of effective tiller showed high heritability along with genetic advance as percent of the mean (GA%) value. A total of 24 alleles were detected by 3 SSR markers. The mean gene diversity and Polymorphism Information Content (PIC) values was 0.821 and 0.797, respectively. Dendrogram constructed based on SSR markers clustered the genotypes into six distinct clusters. Combining molecular and morphological evaluation data eight mutant lines, N10/300/P-2-3-5, N10/300/P-2-3-5, N10/300/P-2-3-5-2, N1/300/P-2-3-5, N1/300/P-2-3-5, N1/250/P-7-6-4-1, N10/300/P-2(1)-4-1 and N1/250/P-7-3-7-1were selected as desired mutant lines having good yield attributing characters and could be recommended for further evaluation in rice breeding program.
