These sets of experiments were conducted at Faculty of Agriculture Sebelas Maret University and the Central Experiment Station of Agricultural Faculty, Sebelas Maret University at Jumantono, Karanganyar, Central Java. The experiments were conducted under greenhouse, laboratory and field condition for each year, while the duration of this research was for two years. The specific objectives of the experiments were: (i) to determine the changes of some morpho-physiological characteristics of water stress soybean and those of unstressed plants at different growth stages; (ii) to evaluate relationship between morpho-physiological traits associated with water stress resistance and yield of soybean. In this study consists some experiments, there are: (i) about response of some soybean cultivars to water stress in screen house and field condition; (ii) about germination response of some soybean cultivars in different concentration 0f PEG; (iii) a bout recovery survival and recovery of soybean seedlings after heat treatment. The plants were well watered before thetreatment. Based on the result of the experiments, the following conclusion could be made: (i) water stress reduced growth, yield and yield components 0 f a II soybean c ultivars used; (li) PEG induced water stress resulted in lower germination, shorter root and shoot length, and increase root-shoot ratio; (iii) the ability of plants to recovery after heat stress have low correlation with drought resistance in this experiment; (iv) the determination of root-shoot ratio in the seedling stage was shown to be suitable screening techniques used to study water stress resistance.© 200'3Jurusan Biologi FMIPA UNS SurakartaKey words: soybean (Glycine max L.), cultivars, water stress.

In Egyptian sugarcane breeding program, a pot experiment was carried out during 2019 season at Agricultural Research Station, Giza Governorate (latitude 26o 33? N and longitude 31o 12? E), Egypt, to evaluate twenty sugarcane clones, compared with the cultivated variety GT.54-9, under three irrigation water levels IWL (100, 80 and 60% of IWL). The traits FW of the shoot and root, root: shoot ratio, LAI, LAR, Chla, Chlb, Chla: Chlb ratio, carotenoids and proline were assessed. From this study clones 17 had height shoot fresh weight under water stress condition, as same as, clones 1, 18 and 19 had great behavior under water stress. In addition to most of sugarcane tested clones were not affected by increase the degree of water stress from 100 to 80% of IWL. The LAI, Chl.a and Chl.b traits showed the high correlation with shoot fresh weight, whereas, proline had strong relationships with root fresh weight under sugarcane drought stress.

Four soybean (Glycine max L. Merril.) cultivars were contrasted in relation to germination and vigour of seedlings, when seeds were submitted to water stress induced by mannitol or sodium chloride. Water stress affected seed germination and seedling development, however, seedling development was affect in higher osmotic potential (-0.3MPa) than the necessary to affect germination -1.2MPa when induced by mannitol or -0.6MPa when induced by sodium chloride. 'Pioneira' and 'Xingu' cultivars had high development in low water availability and/or salinity conditions.

Seven single strains and a commercial mixture of Bradyrhizobium japonicum were evaluated in association with two early-maturing Canadian soybean (Glycine max (L.) Merrill) cultivars, Maple Presto and Maple Amber. Inoculated and uninoculated plants were grown in pails outdoors. Soil temperature at 15 cm depth was monitored throughout the experiment. At the V2, V3, R2 and R4 growth stages, whole plants were removed from the pails. Nodules were counted and weighed; roots and tops were separated, weighed and analyzed for total nitrogen. Bradyrhizobium japonicum strains 61A148, 61A196, 61A194 and 61A155 were similar in effectiveness, but superior to strains 61A124a, 61A118b, 61A101c and the commercial mixture in earliness of nodule formation, number and weight of nodules per plant, and in promoting greater root and top growth and plant nitrogen accumulation. There were indications that soil temperature may have affected nodulation. Maple Amber showed the greater potential for symbiotic nitrogen fixation. This cultivar supported earlier nodulation, had a greater number of nodules, accumulated more nitrogen in the tops and roots and had greater growth than Maple Presto.Key words: Soybean, Glycine max (L.)

Hill Plots

Soybean (Glycine max (L.) Merr.) cultivars were tested for yield at various populations in hillplots that had plants compactly clumped and in comparative hill and row plots. Results indicated that thinning to a uniform stand should be worthwhile in cases where population varies and that selection in hills for material to be grown in rows could be from 43 to 95% as effective as direct selection in row plots.Key words: Glycine max, soybean cultivars, plant density, yield, hill plots, selection

Stems And Leaves

Westag 97 has larger capacity of Cd accumulation in roots which prevents Cd from translocating into stems and leaves; conversely, AC Hime has smaller capacity of Cd accumulation in roots; more Cd is transported into stems and leaves. The different capacity of Cd in roots between Westag 97 and AC Hime causes the different Cd concentration in seeds. Meanwhile, according to the different expression levels of RSTK, ISCP, and H+-ATPase between Westag 97 and AC Hime, RSTK may be involved in transporting Cd into stems and leaves; H+-ATPase may be correlated to the capacity of Cd accumulation in roots; and Cd caused some changes of fundamental life process which leaded to the different expression patterns of ISCP between Westag 97 and AC Hime.

Phytophthora Resistance

Four Japanese soybean (Glycine max (L) Merr.) cultivars (Fujiotome (PI 360836), Misaodaizu (PI 360839), Nezumisaya (PI 360841) and Honiku 65 (PI 360837)) were evaluated for Rps alleles conferring resistance for Phytophthora megasperma (Drechs.) f. sp. glycinea (Hildeb.) Kuan & Erwin. Fujiotome contains Rps1-a and Rps5; Misaodaizu contains Rsp1-c and Rps3; and Nezumisaya contains Rps1-b and a new allele, designated Rps? (Nezumisaya). Honiku 65 is susceptible but two variants obtained from it each contain a new Rps allele designated Rps? (OX939) and Rps? (OX940).Key words: Soybean, Phytophthora resistance
