Genetic variation of 1RS arm between sibling wheat lines containing 1BL.1RS translocation
3 sets of sibling 1BL.1RS translocation wheat lines (each set containing 2 sibling lines) derived from 3 different F4 single plant. Between 2 sibling wheat lines, different resistance to powdery mildew was observed. In addition, different bands in α-gliadin mobility zone between 2 sibling wheat lines were also significantly observed by acid polyacrylamide gel electrophoresis (A-PAGE)....

Comparative analysis of genetic and morphologic diversity among quinoa accessions (Chenopodium quinoa Willd.) of the South of Chile and highland accessions
Quinoa (Chenopodium quinoa Willd.) is a widely consumed food crop and a primary protein source for many of the indigenous inhabitants of the Andean region in South America. Identification of quinoa cultivars has been based on phenotypic characters. In the present work, the level of polymorphism and the genetic relationship were studied by means of molecular markers using the amplified fragment...

Interactive effects of P supply and drought on root growth of the mycorrhizal coriander (Coriandrum sativum L.)
Arbuscular mycorrhizal fungi (AMF) are among the most important plant root symbiosis fungi enhancing plant P uptake. This research was conducted in Iran during 2006. The experimental design was a split factorial on the basis of completely randomized block design with four replicates. The control and AM species, Glomus hoi were assigned to the main plots and the...

Absorption spectrum estimating rice chlorophyll concentration: Preliminary investigations
Our objective in this study was to develop spectral absorption indices for prediction of leaf chlorophyll concentration based on blue/yellow/red/ edge absorption spectrum. Two field experiments were conducted to study the response of chlorophyll index based on leaf absorption spectra to chlorophyll concentration in rice. The ultimate, penultimate and third expanded leaves were sampled for...

Genetic diversity of salt tolerance rice landraces in Vietnam
A collection of 200 salt tolerance rice landraces was assed for genetic diversity using quantitative agro-morphological characters. ANOVA showed highly significant differences (LSD 0.01) among the traits assessed such as grain length, grain width, number of unfilled grains, 1000-grain weight, leaf length and leaf width except panicles per plant and yield. Correlation coefficients showed that all the traits were highly...
