In 2007 and 2008, the influence of pollen source on the shell and kernel traits of resulting seeds and on fruit set was examined to evaluate the potential for Xenia or Metaxenia in Persian walnut. Pistillate flowers of ‘Jamal’, ‘Chandler’, ‘Hartley’ and ‘Pedro’ were crossed with the pollen of ‘Serr’, ‘Z60’ and ‘Damavand’. The pistillate flowers on each female parent were covered about one week...

to evaluate the morphological diversity of some almond cultivars and genotypes, an experiment was carried out on 55 iranian and foreign genotypes. twenty-nine quantitative and qualitative characteristics of nuts and kernels as well as 4 phenotypic characteristics of almond trees were evaluated. analysis of variance and means comparisons indicated that all the characteristics of the examined cul...

a field experiment was conducted to study the physical properties of maize grain in response to different urea fertilization methods (urea foliar spraying and soil application), three harvest times (grain moisture content of 20, 30 and 40 pecent) in four maize hybrids (three foreign hybrids e.g. ns640, jeta600 , konsur580 and one common hybrid, sc704 as control) at khorram abad agricultural res...

a randomized complete block design with four replications and a split plot arrangement was conducted in 2010, in order to study the effect of limited irrigation on yield and yield component of sweet corn. water levels were (100%, 80%, and 60% replacement of plant water requirement) which served as main plots. subplot was a factorial arrangement of three different sweet corn varieties (merit, ob...

Fatty Acids, α-tocopherol, β-caroten, minerals, and some pomological properties of walnut genotypes from four locations (Iğdır, Tuzluca, Karakoyunlu, Kağızman) of Aras Valley (Eastern Turkey) were examined. In this study, the differences among the genotypes were determined in terms of some fruit characteristics, oil and protein contents, fatty acid composition, selenium content, α-tocophero...

for a comparison and grouping of 72 almond cultivars and genotypes, 30 traits including; 12 phenological and vegetative characters plus 18 traits related to nut and kernel were assessed, according to almond universal descriptor. the results revealed that some such traits as growth habit, flower color, nut weight, shell hardness and kernel taste carried high coefficients of variation. simple cor...

abstract almond is an important nut tree which is cultivated in many mediterranean countries. this study was carried out to study some vegetative and reproductive traits as well as qualitative and quantitative characteristics and their correlation in some self-compatible and self-incompatible genotypes obtained from crossing between touno (male parent) and shahrood 12 (female parent). quantitat...

a partial set of diallel crosses conducted among seven bread wheat genotypes contain (gasspard,m86-4,m86-6,dn-11,ws82-9 and m86-12) along with 21 hybrid, based on randomized complete block design(rcbd) with three replication were evaluated. the experiment was accomplished in a research field of agriculture and natural research center of tehran province in 2012-2013 in order to study genetic ana...
