Genetic maps for two pear cultivars ‘Red Bartlett’ (Pyrus communis L.) and ‘Nanguo pear’ (Pyrus ussuriensis Maxim.) were constructed using SRAP molecular markers. The mapping population consists of 74 F1 individuals derived from the cross of a cultivar ‘Red Bartlett’ with good fruit quality as the female parent and a cultivar ‘Nanguopear’ with good cold tolerance as the male parent. Linkage map...

22 Journal of Plant Registrations, Vol. 3, No. 1, January 2009 ‘N8101’ soybean [Glycine max (L.) Merr.] (Reg. No. CV-498, PI 654355) was developed using conventional breeding methods from a cross of a small-seeded germ plasm NC114 and the small-seeded cultivar N7101. An F3–derived selection, N8101 was tested as NTC02AXB-717 in multiple environments in North Carolina and the southeastern United ...

The contents and antioxidant ability of various classes of phenolic compounds present in the seeds of twenty soybean hybrids were evaluated. Total phenolics, tannins and proanthocyanidins were determined spectrophotometrically, after extraction of seeds with 70% aqueous acetone. In addition, the flavonoid contents were determined. The antioxidant activity of aqueous acetone extracts was evaluat...

pyramiding genes related to grain quality and resistance through marker assisted selection (mas) is an important approach in rice breeding programs. marker-assisted selection can be used for monitoring the presence or absence of these genes in breeding populations and can be combined with conventional breeding approaches. this study is a part of cultivar development program in iran through inte...

rootstock and cultivar selection is the most critical decision at the time of an apple orchard establishment. tree size, yield and fruit quality are affected by roostock and cultivar. non-sufficient study of rootstocks and cultivars effects on mentioned traits will lead to incorrect result or failure in orchard managing. in this study the effects of three vegetative rootstocks (mm106, mm111 and...

the interaction of genotype × environment effect, because of disordering effect on genotypes selection has special importance in plant breeding programs. therefore to better selection, yield and yield stability might be considered simultaneously. in order to study of grain yield stability and the evaluation of different selection methods efficiency, 18 advanced barely lines were studied in four...
