Soil salinity is one of the most devastating environmental stresses for rice production in the coastal areas of Bangladesh. Improvement in salt tolerance of rice is an important way for the economic utilization of coastal zones. An experiment was conducted at the vinyl house of the Department of Agronomy, Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Bangladesh during December 2016 to April 2017 to determine the effects of different salinity levels on the yield and yield components of some rice (Oryza sativa L.) genotype sand finally, screening of rice genotypes for salt tolerance. The experiment containing four treatments was laid out in a complete randomized design with five replications. The treatments were four levels of saline water with electrical conductivities at control (0.3 dSm-1), 5, 10 and 15dSm-1. Based on screening at germination stage, relatively salt-tolerant eleven genotypes with two check varieties were used in this experiment. The study showed that increase in salinity level significantly decreased yield and yield contributing characters of rice. However, among the eleven, three genotypes (Chapali, Patnai 23 and Soloi) were considered as moderately salt tolerant at 15 dSm-1 on the basis of their yields and yield contributing characteristics such as plant height reduction, total tiller reduction, effective tiller reduction, reduction of fertile grains per panicle, grain yield and relative grain yield. Therefore, Chapali, Patnai 23 and Soloi might be recommended as moderately salt tolerant rice genotypes. The Agriculturists 2018; 16(1) 65-77

An experiment was conducted at the Laboratory of Agronomy Department, Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur from July-June, 2009-2010 to evaluate the rice (Oryza sativa L.) genotypes for their tolerance to salinity. One hundred rice genotypes and two check cultivars (Pokkali as tolerant and IR29 as susceptible) were exposed to solution of Electrical Conductivity (EC) of 10, 15, and 20 dSm-1 (5:1 molar concentration of NaCl and CaCl2 solution) at germination and early seedling stage. Based on visual salt injury symptoms at 15 dSm-1, 13 genotypes were found fairly tolerant to salinity. However, among the 13 genotypes, only Patnai23 showed higher germination index and seedling relative dry weight than the check salt tolerant Pokkali at 15 dSm-1. Beside these, performance of Awned-1, Nonasail and Soloi was also well at this level. The genotypes Patnai23, Awned-1, Nonasail and Soloi showed the best performance under saline condition.

Rice is an important commodity for the majority of the population, especially in the continent of Asia use rice as a staple food. The state of Indonesia and East Timor, rice as the main food source that needs continue to increase because in addition to the population continues to grow at a rate of increase of about 2% per year, as well as the change in consumption pattern of the population of non-rice to the rice. Interest characterization and evaluation of the appearance of rice(Oryza Sativa L.) locally Timor Leste and Indonesian rice are getting Local rice genotypes Timorese suitable for cultivated in paddy fields. This research using a randomized block design (RBD) consisted of 9 treatments and 3 replications. The materials used are high-yielding rice varieties namely IR-3 64, Ciherang, Cimelati and 6 local rice genotypes Timor Leste, namely Hare Foam, Fafulu Hare, Hare Bauk Morin, Mean Hare, Hare and Hare Modok Fulan. Results showed that the highest plant length at the age of 10 MST contained in the local rice Hare Bauk Morin(134.67 cm), Number of tillers(40.30) the number of leaves(4.64).Flowering date and time of harvest shortest genotypes present in Morin namely Hare Bauk flowering date (39 days) and time of harvest (105 days). The highest number of panicles contained in Hare Mean genotype, high-yielding varieties IR64, Ciherang and Cimelati. The length of the longest panicle genotypes present in Foam Hare, Hare Hare Fafulu, and Fulan. The number of filled grains per panicle most contained in superior varieties IR64, Ciherang and Cimelati. The highest weight of 1000 grains contained in Cimelati varieties (vu3) with Hare Bauk Morin, IR64 and Cherang varieties. The highest rice yield for local rice genotypes present in Hare Bauk Morin (G3) of 9.79 ton.Ha-1 while yielding varieties there exist varieties Cherang (vu2) of 9.74 ton.Ha-1.
