Physiological traits of endornavirus?infected and endornavirus?freecommon bean (Phaseolus vulgaris) cv Black Turtle Soup

Abstract

AbstractThis study evaluated the physiological traits of eight lines of common bean (Phaseolus vulgaris) cv. Black Turtle Soup,four of which were double-infected with Phaseolus vulgaris endornavirus 1 and Phaseolus vulgaris endornavirus 2, andfour of which were endornavirus-free. Plants from all eight lines were morphologically similar and did not show statisticallysignificant differences in plant height, wet weight, number of days to flowering and pod formation, pods per plant, podthickness, seed size, number of seeds per pod, and anthocyanin content. However, the endornavirus-infected lines had fasterseed germination, longer radicle, lower chlorophyll content, higher carotene content, longer pods, and higher weight of 100seeds, all of which were statistically significant. The endornaviruses were not associated with visible pathogenic effects
