This rose virus is of particular importance to rose hybridizers as the literature reports that seed transmission that exceeded 50% in rose has been observed.

Abstract: "The pollen- and seed-borne ilarviruses pose a substantial threat to many specialty crops, including berries, rose, and tree fruit, because there are no efficient control measures other than avoidance. The case of Blackberry chlorotic ringspot virus (BCRV) is of particular interest because the virus has been found to be an integral part of blackberry yellow vein disease and is widespread in rose plants affected by rose rosette disease. This study provides insight into the epidemiology of BCRV, including incidence in blackberry and rose; host range, with the addition of apple as a host of the virus; and seed transmission that exceeded 50% in rose. Sensitive detection protocols that can be used to avoid dissemination of infected material through nurseries and breeding programs were also developed.

From a February 2013 paper, also in the journal Plant Disease (volumn 97): " The virus is widespread in the eastern part of the United States, especially among wild roses where the vast majority of the samples tested were infected with the virus. Given that there are several reports of thrips and bees transmitting ilarviruses as a function of moving pollen from infected to healthy plants (11,105), the wild rose population may be a significant reservoir of the virus. As seed is another means of transmission of ilarviruses, several hundred seeds from rose, blackberry, and herbaceous plants were tested, and the virus was found to be transmitted at high rates (87). The virus was found to be the second most widespread virus in BYVD-affected plants and has been identified in Arkansas, Florida, North and South Carolina, Missouri, Oklahoma, and Oregon (I. E. Tzanetakis, S.W. Scott, B. Poudel, unpublished). "
