Pear (Pyrus spp) is an important fruit crop, grown in all temperate regions of the world, with global production ranked after grape and apples among deciduous tree crops. A high-density linkage map is a valuable tool for fine mapping quantitative trait loci (QTL) and map-based gene cloning. In this study, we firstly constructed a high-density linkage map of pear using SNPs integrated with SSRs,...

Pruning is crucial to balance productivity and fruit quality in blueberry orchards. Slight, conventional and severe pruning treatments were applied on 4and 5-year old bluberry plants cultivar ‘Brigitta’ to evaluate their effect on yield, leaf area, gas exchange and fruit load as driver of fruit quality traits. Yield and berries per plant decreased with increasing pruning severity, whereas canop...

in order to prevent the shrinkage of olive fruit and maintain its fresh being, and  also to increase the oil content and dry matter, the effect of kaolin at three levels of application (0, 2.5% and 5%) on four varieties of olive (mission, conservolea, keillet, blady) was evaluated within a period of four months, in ahwaz, the tests being repated in 3 replicates. results revealed significant eff...

in order to estimate heritability, heterosis, general and specific combining ability and relationships between them in traits of fruit number per plant, days to the first fruit harvest, yield per plant, average fruit weight and rind thickness, seven local populations of iranian melon (‘tashkandi’, ‘khatouni’, ‘garmak’, ‘aran1’, ‘mirpanji’, ‘suski-e-sabz’ and ‘golpaygan’) were crossed using a co...

Genetic architecture of branch traits has large influences on the morphological structure, photosynthetic capacity, planting density, and yield of Upland cotton (Gossypium hirsutum L.). This research aims to reveal the genetic effects of six branch traits, including bottom fruit branch node number (BFBNN), bottom fruit branch length (BFBL), middle fruit branch node number (MFBNN), middle fruit ...

iran, with a long history of apricot cultivation is one of the most important apricot producers in the world. centuries of sexual reproduction via seed, have developed many divergent variations of apricots in iran. however, unfortunately there is no comprehensive report available concerning its diversity and genetic make-up. in this study, 39 iranian apricot cultivars as well as accessions, nat...

the aim of the present study was to examine the effect of grafting of watermelon hybrids ‘obla f1’ and ‘vanessa f1’ on to cucurbita maxima × cucurbita moschata rootstock tz 148 and lagenaria sp. rootstock ‘dias f1’, on the volatiles and yield of fruit and the plant growth. fruit volatiles analysis showed the presence of two aldehydes, namely (e)-2-nonenal and (e,z)-2,6-nonadien-1-al, with (e)-2...

to determine the effects of different pollen types and suitable pollination time in medjhol date palm, an experiment was carried out with three pollen cultivars: ghaname, vardy and samesmave and two pollination times (1-3 days before or after spathe opening) during 2010-2011 in date palm and tropical fruit research institute in ahwaz. the results showed that the vardy pollen had the most signif...
