Induced intermedium mutants in barley: origin, morphology and inheritance

Genetic Studies of Induced Mutants in Melilotus alba. II. Inheritance and Complementation of Chlorophyll-deficient Mutants

Six ethyl methanesulfonate-induced mutants of Melilotus alba Desr. were studied. Five of the mutants behaved as monogenic recessives. In the sixth mutant, two independent recessive alleles were responsible for the observed phenotype. Of these two genes, one had a phenotypic effect similar to the five single-gene mutants. The other (the veined gene) caused a chlorophyll deficiency in which the l...

Root Hair Mutants of Barley

Almost sixty mutants with shortened or reduced root hairs or without root hairs at all have been isolated among 2000 M1 plant progenies (20.000 M2 seeds) of the spring barley cultivar “Lux” after sodium azide mutagenesis. One group of 25 mutants show fairly stable phenotype while 33 lines have unstable, indistinct or segregating phenotypes. The mutants were selected after 3 to 4 days growth in ...

A Genetic Study of Linkage and Inheritance in Barley

Barley Developmental Mutants: The High Road to Understand the Cereal Spike Morphology

A better understanding of the developmental plan of a cereal spike is of relevance when designing the plant for the future, in which innovative traits can be implemented through pre-breeding strategies. Barley developmental mutants can be a Mendelian solution for identifying genes controlling key steps in the establishment of the spike morphology. Among cereals, barley (Hordeum vulgare L.) is o...

morphology, geochemistry, mineralogy, and micromorphology of soils of hormozgan province in relation to parent materials

ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...
