A phenotypic segregation of kanamycin resistance conferred by nosnptII was investigated in two groups of transgenic cucumber lines one containing the PR-2duidA-nosnptII construct and the other with the thaumatinII-nosnptII construct to the third and fifth generation, respectively. Expression of the nptII gene was more stable and predictable in the progeny of the PR-2d lines than that of thaumat...

Culinary cassava (Manihot esculenta L.) qualities that make a variety popular are a function of starch physicochemical properties. Hence, in response to inferior root qualities in some released cassava varieties in Uganda compared to the local germplasm, a study was undertaken to examine: (i) starch physicochemical characteristics in both introduced and local varieties; and (ii) the variation i...

The course of hypertension development in young spontaneously hypertensive rats (SHR) was studied by the measurement of changes in systolic blood pressure (BP), body weight, and heart rate (HR) at 2, 3, 4, and 6 wk of age. To achieve this, we compared inbreeding lines of SHR and Wistar-Kyoto rats (WKY) to determine if differences in BP, body weight, or HR were present among inbreeding lines of ...

inroduction: inbreeding is defined as the probability that two alleles at any locus are identical by descent and occur when related individuals are mated to each other. the initial consequence of inbreeding is inbreeding depression reducing the performance of growth, production, health, fertility, and survival traits. this concern has become more serious in animal breeding nowadays, in which se...

grapevine is among some of the most important horticultural crops in the world and as well in iran. since last century attempts have been made throughout the world to improve grapes. research in grape breeding for the purpose of improving table grape as well as raisin traits has started since 1996 in iran with crossing some selected seedless (askary, yaghoti, bidane sefid (sultana) and bidane g...

In this study, we identified simple sequence repeat, ampli-fied fragment length polymorphism, and sequence-related amplified poly-morphism markers linked to quantitative trait loci (QTLs) for resistance to white mold disease in common bean progenies derived from a cross between lines CNFC 9506 and RP-2, evaluated using the oxalic acid test and using Bayesian analysis. DNA was extracted from 186...

line yesevi-93 (cultivar abidar) was first introduced to dryland agricultural research institute (dari) through the international winter preliminary barley yield trials (iwpbyt) in 1994. it was selected as one the most high yielding lines based on observational and statistical trails (regional barley yield trials) carried out in different locations during 1997-2000. the average yield of abidar ...
