  In order to study cause and effect of seed yield with some agronomical traits in bean genotypes, two experiments were conducted under field conditions. Twenty five common bean genotypes were sown in 2 separate RCB design with three replications under non-infected and infected conditions. First, phenotypic correlation coefficient of traits with each other was counted. At non-infected conditions number of secondary stem, harvest index, reproduction period and under infected conditions number of seeds in plant, number of seeds in pod and harvest index showed significant correlation with seed yield at 0.05 & 0.01 probability levels. Stepwise regression and then path analysis were used to determine the traits that were effective on seed yield. In stepwise regression analysis seed yield was the dependent and other traits were as independent variables. At non-infected conditions number of secondary stem, harvest index and main stem length were entered in regression model respectively and explained 84% of seed yield variations. In this manner, under infected conditions, harvest index, plant weight and number of seeds in pod justified 93% of seed yield variations. On the basis of achieved results, harvest index was introduced as profitable selection index at non-infected and infected conditions. In order to results of path analysis after harvest index at non-infected conditions number of secondary stem and at infected conditions number of seeds in pod were introduced as suitable indices.

  Bean common mosaic virus is widely spread in the world, and also causes functional impairment in the quality of the product. Using tolerant and resistant genotypes is one of the main approaches to the management of this disease. For this purpose, the present study was conducted in two separate sections. 20 cowpea genotypes were studied in two separate experiments, with and without infection in a randomized complete block design, with three replications in greenhouse. The infection was conducted in 2-leaf phase by mechanical inoculation and morphological evaluation was recorded 21 days after infection. ELISA test was used to determine the infection rate of genotypes. Infection of cowpea genotypes were also checked by RT-PCR test using specific BCMV primers. Results suggest amplified fragment with length of 373 bp in the infected plants. The infection rate of different genotypes was 66.6 to 80%. According to the symptoms caused by mechanical inoculation with BCMV to cowpea genotypes was scored between 0-4 which used to obtain disease severity. According the all results, the genotypes divided to hypersensitive, sensitive, semi-resistant and resistant group. Manuscript profile
