Abstract Poor germination and subsequent low grain yield of dry seeded upland rice in the existing anaerobic and short niche between lowland rice and dry season crops in the inland valley necessitate the screening of 19 rice varieties. The identification of vigorous growth and short duration upland rice variety in anaerobic condition would optimize this niche. The potted experiment was carried out in the screen house of the Department of Crop Science and Horticulture, Federal University Oye-Ekiti, Ikole campus in 2015 to screen and evaluate the performance of upland rice varieties in inundated soils with a view to selecting the suitable variety or varieties that will fit into the existing niche in the inland valley. The experiment was laid in a complete randomization design and replicated three times. The number of leaves, biomass and grain weight plant−1 of the varieties were significantly (P ≤ 0.05 %) different. The number of tillers observed in WAB 56-104, NERICA 4, NERICA 6, NERICA 3, NERICA 5, NERICA 10, NERICA 9, ARICA 4 NERICA 1, FARO 63, FARO 65 and NERICA 8 varieties were significantly (P < 0.05) lower than those of Igbemo varieties. The numbers of days to 50 % flowering of NERICA 1, NERICA 2, NERICA 10, NERICA 5, NERICA 9, NERICA 3, NERICA 7, NERICA 8, ARICA 4 and WAB 56-104 varieties were the lowest. Although Igbemo brown, Igbemo white varieties had the highest grain yields per plant, their maturity period exceeded the short period. Thus, NERICA 2 and NERICA 5 varieties which had lower number of days to flowering could be considered as candidate varieties that can be optimized in the niche in question.

The study aimed to examine the response of upland rice varieties at germination stage on several PEG (Polyethylene Glycol) 6000 concentration levels and to determine growth characteristics, physiological changes and yield of upland rice varieties under drought stress condition in a pot experiment. The study consisted of two experiments; the first was to study germination and early growth, and the second was to study the vegetative and generative growth of upland rice under drought stress condition. Experiments I and II were conducted in a completely randomized factorial design consisted of two factors and three replications. In experiments I, the first factor was upland rice variety comprised of 10 varieties and the second factor was PEG concentration consisted of four levels. In experiment II, the first factor was upland rice varieties that responded the best to drought stress in experiment I, and the second factor was the drought stress treatment consisted of moisture content at 100, 75, 50 and 25% field capacity. The research was conducted at the Laboratory of Plant Physiology and Biotechnology and the greenhouse of Faculty of Agriculture, Sebelas Maret University (UNS) Surakarta. The results showed that the germination and vigor index decreased with increasing levels of PEG concentration. PEG concentration of 25 g L-1 of water was the most optimum for screening drought resistant upland rice. In experiment I, Towuti, Situ Patengang, Kalimutu and Gajah Mungkur varieties showed the best response to drought stress. Increased intensity of drought stress resulted in a reduction of plant height, number of tillers, dry weight, relative growth rate, leaf area, number of grains hill-1, 1000 grain weight, dry grain weight hill-1 and root dry weight. The drought stress also caused an earlier flowering date and increased percentage of empty grain. Based on the dry grain weight hill-1, Towuti exhibited a higher drought resistance level than Gajah Mungkur, Situ Patenggang and Kalimutu.

Aluminum (Al) is one of the major limited factors in crop production on acid soils. Aluminum tolerant plants can beselected from plant breeding program by one of the physiological parameters representing Al tolerance character,such as root re-growth capability during recovery from the Al-stress. In this study we determined the concentrationand time exposure of Al stress that was able to differentiate the response of three local upland rice varieties(Grogol, Hawarabunar and Krowal) and an Al-sensitive rice variety (IR64) to Al-stress, and evaluated the effectivenessof root re-growth (RRG) characters as an Al tolerance parameter in rice. The study consisted of three experiments,which were 1) nutrient culture experiment with different Al concentration treatments in growth chamber, 2) potexperiment in greenhouse using Jasinga yellow red podzolic acid soil containing 26,66 me/100 g Al and pH 4,6 asplanting media, and 3) phenotyping of F2 population using RRG character. The results showed that Al treatment at15 ppm for 72 h was able to distinctly differentiate between Al-tolerant (Grogol and Hawarabunar) and Al-sensitivevarieties (Krowal and IR64). Planting of the rice varieties on acid soils showed similar result as that of the nutrientculture. Phenotyping of F2 population using RRG character indicated the existence of RRG value variation. Thesevariations demonstrated that RRG character can be used as an Al tolerance parameter in rice and therefore can beeffectively applied to screen rice F2 population that segregate to Al tolerance character.

Rice (Oryza sativa L.) is a species of crops which is highly sensitive to drought. The sensitivity to water stress varies from genotypes to genotypes of rice. An experiment was performed to compare twenty-five different rice genotypes for drought tolerance in the seedling stage at Gokuleshwor Agriculture and Animal Science College, Baitadi Nepal from July to August 2018. The genotypes were tested under two conditions viz., water stress and non-water stress. The research work was carried out in a completely random design (CRD) with three replications. The results exhibited the height of seedling, length & breadth of leaf, number of leaves/plant decreased, and number of leaves shedding increased under water stress condition. Clustering was done by the method of average linkage, and genotypes were categorized into five clusters. The genotype, namely Radha 11 grouped in Cluster-V had higher plant height, bigger length & breadth of leaf, maximum number of leaves/plant and minimum number of leaf shedding. Thus, this genotype showed the best performance for morphological traits under water stress condition. Therefore, this genotype Radha 11 can be utilized further for developing rice variety with drought-tolerance.
