【 摘 要 】

Popping maize is a specific type of maize differing from other types of maize by its capability to form a large puff or flake after explosive 'pop' that is a response to heating. Besides grain yield, an economically important trait, it is necessary that popping maize hybrids are characterized by a great popping volume and quality and testy flakes as well as other essential production traits. The grain yield of 12 selected popping maize hybrids was observed and the interrelationship among the grain yield, popping volume and the number of kernels per 10 g was established. Obtained results point out to a negative statistically significant correlation (-0,684*) between the grain yield and the popping volume. Furthermore, insignificant negative correlations (-0,135 and -0,399) were established between the grain yield and the number of kernels per 10 g and the popping volume and the number of kernels per 10 g, respectively. The traits observed in the present study are the quantitative ones, that is, their expression is determined by the greater number of genes and by environmental conditions. .
