Morphological and genetic characteristics of hybrid combinations of Dactylis glomerata

Y. F. Zhao, Zhang, X. Q., Ma, X., Xie, W. G., and Huang, L. K., Morphological and genetic characteristics of hybrid combinations of Dactylis glomerata, vol. 13, pp. 2491-2503, 2014.

Six F1 populations derived from crosses among 4 orchardgrass (Dactylis glomerata L.) cultivars were studied by morphological and simple sequence repeat molecular markers to test for hybrid vigor and a correlation between genetic distance and heterosis. Heterosis was observed for days to length of culm, leaf traits, tiller numbers, etc. Significant differences between obverse and inverse crosses were found for eleven traits. A cytoplasmic effect existed for the agronomic traits considered in this study.
