The Genetic Structure of Wild Orobanche cumana Wallr. (Orobanchaceae) Populations in Eastern Bulgaria Reflects Introgressions from Weedy Populations

Table 5

Number of emerged Orobanche cumana shoots per sunflower plant (mean ± standard deviation) in the evaluation of O. cumana populations CUMBUL-1, CUMBUL-2, and CUMBUL-4, collected in Bulgaria on Artemisia maritima, CUMBUL-5_1, collected in Bulgaria on Anthemis arvensis, and control population OC-88, collected in Spain on cultivated sunflower, on two sunflower lines (B117 and B206) with no genetic resistance to O. cumana, conducted in pots in 2007^a.

	B117^b	B206^a
CUMBUL-1	14.5±9.9^b	35.3±13.1^c
CUMBUL-2	39.5±7.7^c	36.3±11.3^c
CUMBUL-4	5.2±4.7^a	1.7±1.0^a
CUMBUL-5_1	11.5±8.9^ab	14.3±4.5^b
OC-88	10.3±6.0^ab	18.5±7.2^b
