Correlation, regression and cluster analysis for yield and yield components of wheat under deficit irrigation condition and spraying phosphorus S. Moradizadeh *1, F. Paknejad 2, S. Vazan 3, M. H. Shirzadi 4 The relationships of some wheat traits and theirs direct and indirect influence on the grain yield (GY) were investigated. In base of important of subject this research conducted in form of factorial in based on random complete blocks design with four replication in research field farm of Islamic Azad University of Karaj branch in 2010-2011. Experimental treatments including: Low irrigation in three levels (Normal irrigation (NI), Non irrigation from stem elongation to anthesis (NI1), Non irrigation from anthesis to maturity (NI2)) and phosphorous spraying in four density: 0, 4, 6, 8 kg/ha from source of Potassium de-hydrogen Phosphate (KH 2 PO 4 ). According to results observed significant correlation(α = 0.01) between GY and Biomass (TDW), 1000 grain weight (TGW), and harvest index (HI). In stepwise regression method under NI condition, some traits including Biomass &harvest index and under NI1 condition, grain number per ear(gne), ear number per m 2 (EN), plant height(ph) & unit grain weight(ugw) and under NI2 condition some traits including biomass(tdw), harvest index(hi), 1000 grain weight(tgw) & fertile spikelet number (NFS) remained in final model R 2 was equal to 0.97, 0/99 and 0.997, respectively. Path analysis results showed that the biomass has a highest direct and positive effect under normal irrigation (1.511) and NI2 condition (0.828), on GY, but in NI1 condition, highest direct and positive effect related to grain number per ear(gne) trait (1/231). Among the Other traits, grain number per ear (0/849) trait, has a highest indirect effect on GY. Totally designated increasing of Biomass and grain number per ear traits are important way for increasing of GY trait. Keywords: Path analysis, Correlation,Wheat,Drought stress 1- MSc.

Inheritance of Some Traits Associated With Resistance to Sunn Pest (Eurygaster integriceps) by Generation Mean Analysis in Bread Wheat M. Zabet 1 and K. Mostafavi 2 * To study of resistance to sunn pest (Eurygaster integriceps) in bread wheat, parents including Falat (Resistant) sardari (Susceptible) were crossed and generations of F 1, F 2, BC 1 and BC 2 were obtained.the six basic generations (parent, first and second filial generations (F 1, F 2 ), first and second backcrosses (BC1, BC2) of crossings were planted in a Randomized Complete Block design with three replications at the Research Farm of Islamic Azad University, Karaj, Iran. Analysis of weighted variance showed that differences between generations were significant for all traits, except for total seed weight in damaged spikes. Joint scaling test showed that both additive and dominance componenets were involved and at the most time epistasis was implicated.in spite of this the additive components were most important. In seed-damaged percentage, as the most important trait, m, d, h, I and l model was significant.

QTL Analysis for Resistance to Sunn pest (Eurygaster integriceps) in Bread Wheat Using SSR and AFLP Markers M. Zabet 1 *, K. Mostafavi 2 Wheat is usually injured by sunn pest (Eurygaster integriceps) and this damage is important for farmers and bakers. The sunn pest is very serious in IRAN. Using of resistant varieties in integrated management program is one of the suitable methods. In order to map the Quantitative Trait Loci (QTLs) for sunn pest resistance in bread wheat and to determine the contribution of each QTL in phenotypic variations, a F2:3 derived population from crossing between cv. FALAT (resistant) and line 12 (susceptible) were evaluated. The traits under study included: weight of five damaged spikes, weight of damaged seed in damaged spikes, weight of fifty damaged seeds and damaged seed percent. The linkage map was constructed using 35 SSR and 68 AFLP markers. The markers were assigned to 27 linkage groups using linkage analysis. Total map length was 875.6 cm with an average interval size of 12.9 cm. For damaged seed percent, as important trait, four QTLs were identified which explained 44% of the phenotypic variations. According to these results one can hope to identify the related traits with resistance using molecular markers and QTL analysis.

Identification of QTLs Controlling Yield and Seed Weight in Sunflower under Normal and Water Stress Conditions A. Nabipour 1 Drought is one the most important factors limiting yield and culture area of crop plants which also may modify the yield quality. Identification of genetic factors improving plant drought tolerance might increase the efficiency of breeding programs aimed to attain drought tolerant cultivars. In order to find genomic regions affecting drought tolerance, as well as markers linked to drought tolerance, 100 recombinant inbred lines including their two parents, RHA266 and PAC2, were cultured in field under full and limited irrigation as an alpha-lattice arrangement with two replications. Analysis of variance revealed significant differences among the genotypes in both conditions. QTL mapping using composite interval method resulted in identification of several genomic regions controlling the drought tolerance traits. Some yield QTLs were common in both normal and drought conditions, and some were specific to drought condition. Results suggested that selecting for lines with heavier seeds would result in superior genotypes for drought condition. Markers linked to the studied traits were identified.

Study of relationship between SSR markers of QTL region controlling drought tolerance and some of the phenotypic traits on chromosome 2 of rice P. Niksiar 1, S. Navabpour* 2, H. Sabouri 3, H. Soltanlou 2, M. Rahimi 4 To consider the relationship between allelic diversity of sixteen microsatellite markers of major QTL controlling drought tolerance on chromosome number 2 of rice and some of phenotypic traits in some types of Iranian and experimental imported rice was performed in two molecular and phenotypic parts in Plant breeding laboratory of Gonbad-e-Kavoos university at 2012. Studied characteristics included the root dimension, root weight, root amounts, stem weight, stem length, root length, genotypic code and biomass. Variance analysis of studied characteristics indicated that there is a very significant difference between genotypes of studied characteristics under the drought conditions. In this study 49 allele was observed that the most amount of allele is related to RM3302 marker with 6 alleles and the most gene variety and the highest PIC were related to RM8030. Stepwise regression analysis was used for relationship between phenotypic traits as dependent variable and alleles as independent variable and showed that 17 alleles have significant association with at least one of the eight phenotypic traits under drought condition that can be profit in breeding with marker assisted selection and produce tolerant variety in the seedling stage in drought stress.

Genotype - Environment Interaction for Oil Percent in Sunflower Varieties Using AMMI Method P. Hejazi 1, A. R. Nabipoor 2, K. Mostafavi* 3, M. Firoozi 4 The interaction between genotype and environment is reason that researchers evaluate new cultivars in wide range of environmental conditions. These information is very useful in determine of cultivar stability and regional adaptability. In order to evaluate stability of open pollination sunflower cultivars for oil percent, an experiment on 10 open pollinated sunflower varieties in five agricultural research centers: Karaj, Urmia, Bojnourd, Shiraz and Islamabad in a randomized complete block design with four replications were done. The interaction of genotype and environment investigated with AMMI method. Three interaction principal components explain over 95 percent of the total variance. In the AMMI1 biplot graph the cultivars: Master, Bulg5, Bulg3 and Islamabad and Bojnourd environments were high in IPCA1 factor and show the greatest influence on interaction effect. Berezans, Favorit, Lakumba, Record and Zaria cultivars and Karaj, Shiraz with Urmia environments have the low IPCA1 and high stability. Base oil performance and stability, Zaria cultivar was the best cultivar. In the AMMI2 biplot graph, Lakumka and Zaria had the least interaction with high common adaptability. Base this graph bulg3 cultivar in Islamabad, Berezans in Karaj and Shiraz, bulg5 in Bojnourd and Favorit and Record in Urmia had the specific adaptability.
