in order to study the effects of shading on head and its near leaves on yield and yield components of spring safflower genotypes, an experiment was conducted in factorial arrangement based on a complete randomized block design with four replications at agricultural research station, faculty of agriculture, birjand university during 2008. factors were including three spring safflower genotypes (...

to investigate the genetic diversity of persian walnut (juglans regia), 608 different walnut genotypes of neyriz region were evaluated for 30 morphological characteristics including kernel color, fruit shape, shell seal, shell texture and kernel plumpness, kernel weight, percentage of kernel as well as thickness of shell. the correlation between was traits in most cases significant at either 1 ...

this research was conducted to study some vegetative and reproductive traits as well as qualitative andquantitative characteristics and their correlation in 80 almond genotypes. qualitative traits were studiedaccording to gulcan descriptor. quantitative traits were analyzed as completely randomized design(crd), with 12 replications. the results showed that genotypes had significant difference i...

Water scarcity in Egypt and globally makes producing new varieties having high grain yield using less water requirements is an important goal for wheat breeders. The present research was conducted to assess the response of sixteen bread genotypes under normal irrigation (five irrigations) low (one irrigation, 25 days, after sowing irrigation.) during 2018/19 2020/21 seasons at Experimental Farm...

self pollinated cultivars of hazelnut are limited mainly due to dichogamy and self- incompability. to enhance productivity of hazelnut orchards, identification and selection of suitable polinizers are necessary. to meet this quest, collection and evaluation of iranian hazelnut germplasm have began by department of horticulture research, seed and plant improvement institute, iran, since 1994. ha...

understanding the relationship between sink and source in maize is of prime importance in maize growing regions. in this study, a field experiment was carried out during spring and summer 2007 in the experimental field of the college of agriculture, shiraz university, to examine the effects of source restriction (defoliation) on sink size (yield and its components) of  sc704 maize hybrid.  a fa...

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 ...

Kernel morphology characteristics of wheat are complex and quantitatively inherited. A doubled haploid (DH) population of the cross RL4452/'AC Domain' was used to study the genetic basis of seed shape. Quantitative trait loci (QTL) analyses were conducted on a total of 18 traits: 14 grain shape traits, flour yield (Fyd), and three agronomic traits (Plant height [Plht], 1000 Grain weight [Gwt], ...
