In the present work we studied the birth order in progenies of lranian survivors of Iraqi chemical attacks during a period from 1984 to 1989. Then we compared the results with the birth order of the control group. Despite a slight difference between the birth order in the two groups of progenies, this was not statistically significant. This does not mean, however, that there are no genetic ...

Bitumen as a binder in coating and insulating materials is modified with polymers to improve its performance in service conditions. Almost all polymers are incompatible with bitumen, and at high temperatures due to relatively very low viscosity of the bitumen phase, are separated from it. These lead to a considerable limitation in the use and handling of polymer-modified bitumens. An understand...

Morpho-agronomic and molecular (RAPD and ISSR markers) data were used to evaluate genetic distances between papaya backcross progenies in order to help identify agronomically superior genotypes. Thirty-two papaya progenies were evaluated based on 15 morpho-agronomic characteristics, 20 ISSR and 19 RAPD primers. Manhattan, Jaccard and Gower distances were used to estimate differences based ...

Although interspecific hybrids between cyclamen (Cyclamen persicum) cultivars and C. purpurascens were produced by using the ovule culture, mode of inheritance of flower pigment remains obscure. Therefore, inheritance of anthocyanin in the petals in the crosses between diploid cyclamen cultivars and C. purpurascens was investigated in the present study. In every cross combination, including the...

seedlessness is the most important trait in table grape and raisin industry which has attracted breeders from long ago. breeding grapes by traditional methods result in low number of seedless progenies and their selection requires long time. therefore, marker-assisted selection (mas) can overcome the selection difficulty and would decrease high cost of progeny maintenance for several years. in ...

An analysis of the offspring of single smooth- and crenate-tail females of Pratylenchus penetrans indicated the existence of progenies containing only males or females. Of the 80 progenies analyzed, 46 contained females with smooth and crenate tails. In general, regardless of the mother's tail type, most females possessed crenate tails, although more crenate-tail females originated from a crena...

Yardlong bean pod used as vegetable in many countries. has agronomic character variability such length, immature and seed colour. The colour are green, whitish green red. Fagiola variety red pod, while "Aura Hijau" pod. aim of research was to evaluate characters F3 progenies. Artificial crossing made between "Fagiola" female parent male produce F1. F1 were self-pollinated F2. Then F2 obtain Pro...
