Genome Size and Environmental Correlations in Maize (Zea maysssp.mays, Poaceae)

Autor: Amilcar M. Chiavarino, Lidia Poggio, C. A. Naranjo, Marcela Rosato

Publikováno v: Annals of Botany. 82:107-115

Variation in the DNA content attributed to sources such as variation in the amount of heterochromatin and occurrence of supernumerary chromosomes (Bs) in native races of maize cultivated at different altitudes (80-3620 m) is discussed. These populati

Publikováno v: American Journal of Botany. 85:1581-1585

In previous papers we found that the frequency of B chromosomes in native races of maize varies considerably in different populations. Moreover, we found genotypes that control high and low transmission rates (TR) of B chromosomes in the Pisingallo r

Genome size and numerical polymorphism for the B chromosome in races of maize (Zea mays ssp. mays, Poaceae)

Publikováno v: American Journal of Botany. 85:168-174

Twenty-one native populations (1120 individuals) of maize from Northern Argentina were studied. These populations, which belong to 13 native races, were cultivated at different altitudes (80‐3620 m). Nineteen of the populations analyzed showed B ch

Genetic control of B chromosome transmission rate inZea maysssp.mays(Poaceae)

Autor: M. J. Puertas, Amilcar M. Chiavarino, C. A. Naranjo, Marcela Rosato, Lidia Poggio

Publikováno v: American Journal of Botany. 83:1107-1112

We selected genotypes of high and low B chromosome transmission rate (TR) in a native race of maize (Pisingallo) from northwest Argentina. We made 20 female OB X male IB and 20 f.lB x m.OB crosses. The former (GOm) showed a large variation of B TR, w
