inheritance of resistance to stripe rust was studied in wheat by determining the responses of 5 hexaploid wheat cultivars and 10 f1 progenies of their diallel mating crosses, against 2 races of pathogen including 174e174a+, 134e134 a+ in completely randomized design with 3 repetitions under greenhouse conditions at tehran university.the components of resistance including latent period, infectio...

Partial or complete sterility is of frequent occurrence in species crosses. Within the same genus certain species are sterile when crossed while ather combinations are completely fertile. Partial sterility may cause the elimination of certain classes of gametes and prevent desired recombinations of characters in the second generation. Sterility may also cause an abnormal vegetative development....

Five tomato cultivars were studied for inheritance of bacterial wilt resistance. Lines AVTO1429, AVTO1424, and AVTO1314 have the resistance gene, Roma VF lacks Valoria Select is claimed to but has not been evaluated. The study, which was carried out in a split plot design, involved six generations backcrosses that conducted greenhouse field. Artificial inoculation Ralstonia solanacearum greenho...

Assessment of combining ability in okra (Abelmoschus esculentus (L.) Moench) was done the current investigation using a line x tester mating design. From 11 female lines and 3 testers, 33 cross combinations were made LxT design, enough F1 seeds produced summer 2021. The planted kharif 2021 to evaluate effectiveness various crosses with three checks. experiment conducted at Breeder Seed Producti...

Stable resistance to infection with Wheat streak mosaic virus (WSMV) can be evolved de novo in selfing bread wheat lines subjected to cycles of WSMV inoculation and selection of best-performing plants or tillers. To learn whether this phenomenon might be applied to evolve resistance de novo to pathogens unrelated to WSMV, we examined the responses to leaf rust of succeeding generations of the r...
