Genetic distances between popcorn populations based on molecular markers and correlations with heterosis estimates made by diallel analysis of hybrids

R. E. F. Munhoz, Prioli, A. J., Júnior, A. T. Amaral, Scapim, C. A., and Simon, G. A., Genetic distances between popcorn populations based on molecular markers and correlations with heterosis estimates made by diallel analysis of hybrids, vol. 8, pp. 951-962, 2009.

Diallel analysis was used to obtain information on com­bining ability, heterosis, estimates of genetic distances by random amplified polymorphic DNA (RAPD) and on their correlations with heterosis, for the popcorn varieties RS 20, UNB2, CMS 43, CMS 42, Zélia, UEM J1, UEM M2, Beija-Flor, and Viçosa, which were crossed to obtain all possible combinations, without reciprocals. The genitors and the 36 F1 hybrids were evaluated in field trials in Maringá during two growing seasons in a randomized complete block design with three replications.
