Abstract. Subekti NA, Sembiring H, Erythrina, Nugraha D, Priatmojo B, Nafisah. 2020. Yield of different rice cultivars at two levels of soil salinity under seawater intrusion in West Java, Indonesia. Biodiversitas 21: 14-20. A tendency to use saline water in rice production is rising in recent years, but the adaptation of variety under saline conditions is still questionable. The aim of the study was to evaluate the response of several rice cultivars on the growth and yield of rice under seawater intrusion in West Java. Two salt-tolerant cultivars (Inpari 34 and Inpari 35), two promising lines (PL-1 and PL-2) and two modern cultivars (Inpari 30 (Ciherang sub1) and Sidenuk) were evaluated in two soil salinity levels. In each farmer's field a Randomized Complete Block Design was applied with three replications per treatment. Results showed that Sidenuk and Inpari 30 produced same yield compared to tolerant varieties and promising lines during dry season under moderate soil salinity. There were not much different among the cultivars tested in terms of plant height and tiller number as well as the biomass and harvest index. However, under high soil salinity seed germination, plant height, number of tillers per plant, above-ground biomass, spikelet number, percent of sterile florets and productivity were significantly affected. Saline tolerant varieties Inpari 34 and Inpari 35 showed their superiority compared to non-tolerant varieties. Both varieties produced 40% higher yield than Inpari 30 (Ciherang sub 1) and Sidenuk.

This study was done with the aims to determine: (i) the correlation between agronomic traits and yield and (ii) the direct and indirect effects of agronomic traits on salt-tolerant rice yield. The field experiment was conducted directly on moderate salinity level of EC= 6.35 dS m-1 during the 2017 winter-spring cropping season in Central Vietnam. Ten salt-tolerant rice cultivars were studied. Results showed that yields of salt-tolerant rice cultivars had a positive correlation with traits of plant height, panicles per plant, panicle weight, and dry biomass, r = 0.3624*, 0.7019***, 0.4530** and 0.7837***, respectively. Total panicles per plant, panicle weight, and the number of grains per panicle directly affected rice yield with coefficients of dC = 0.5524, 0.8294 and 0.4355, respectively. Therefore, these traits should be used as good indicator traits for selecting salt-tolerant rice cultivars for the moderate salinity soil in Central Vietnam.

SUMMARYTen wheat and six barley genotypes were tested for their response to soil salinity regimes varying from 0 to 16 mmhos cm−1. Barley showed remarkable resistance to salt stress, linked to its capability to resist efflux of potassium ions from the plant system. Both crops showed substantial yield reductions at 12 mmhos cm−1, but barley still outyielded wheat by over 50%. There were significant interactions between salinity levels and genotypes in wheat but not in barley.The wheat variety Sonalika showed poor salt tolerance. The implications of these findings in breeding salt-tolerant varieties are discussed.

Fifteen salt tolerant CIP (International Potato Centre) Potato genotypes along with BARI (Bangladesh Agricultural Research Institute) Alu 7 (Diamant) and one local variety viz., Dohazari Sada were evaluated at Bashkhali, Chittagong during 2011-12 to screen the suitable genotypes for cultivation in saline areas of Bangladesh. Diamant and Dohazari Sada and all of the CIP genotypes were found to grow well up to 60 DAP (Days After Planting) at saline areas having healthy plants and no senescence was noticed but after that 61-100% plants died due to high level of soil salinity (6.41dS/m) depending on genotypes. Genotype CIP 112 gave the highest yield (21.07 t/ha) and CIP 102 was comparatively less affected by soil salinity than the other genotypes. However, all the salt tolerant CIP genotypes were found to be promising in the saline soil. DOI: http://dx.doi.org/10.3329/agric.v11i1.15249 The Agriculturists 2013; 11(1) 95-102

ABSTRACTSoil salinity is a worldwide adverse environmental factor for crop productivity and quality in arid, semiarid and coastal areas. In India, approximately 8.5 million hectare of land area is affected by high salinity (EC ≥ 5 dS m−1). Development of salinity tolerant varieties through marker assisted breeding is most efficient and effective strategy for management of soil salinity. WH 1105 is widely cultivated wheat variety with many agronomically superior qualities but is affected by soil salinity. Two genes (Nax1andNax2) for salinity tolerance were introgressed from Kharchia 65 into the genetic background of WH 1105 through marker assisted backcross breeding. BC1F3, BC2F2and F4generations of the cross WH1105 x Kharchia 65 were evaluated for various morphological traits under initial salt stress condition. On the basis of phenotypic and genotypic variations 44 high yielding plants were selected from the cross. Out of 178 SSRs tested, 30 were found polymorphic for background selection of the foreground selected plants. Cluster tree analysis of parents and all the three generations showed that all the selected plants were inclined toward recurrent parent (WH 1105) indicating higher similarity with the recurrent parent. Four plants were selected as high grain yielding and salt tolerant. These plants could be further backcrossed with the recurrent parent to develop salt tolerant wheat lines.

Salt-tolerant turfgrass is highly desirable in areas associated with saline soils or saline irrigation waters. To determine the salt tolerance of 14 saltgrass [Distichlis spicata var. stricta (Greene)] selections, two greenhouse studies were conducted by means of a hydroponic culture system. Five salinity levels (from 2 to 48 dS·m−1) were created with ocean salts. In general, turf quality decreased and leaf firing increased as salinity increased. However, varying levels of salt tolerance were observed among selections based on leaf firing, turf quality, root growth, and clipping yield. Selections COAZ-01, COAZ-18, CO-01, and COAZ-19 exhibited the best turf quality and the least leaf firing at 36 and 48 dS·m−1 salinity levels in both Experiments 1 and 2. At the highest salinity level (48 dS·m−1), COAZ-18 and COAZ-19 exhibited the highest root activity among all accessions. Salinity levels that caused 25% clipping reduction ranged from 21.2 to 29.9 dS·m−1 and were not significantly different among entries. The data on 25% clipping reduction salinity of saltgrass generated in this study rank saltgrass as one of the most salt-tolerant species that can be used as turf.
