Microsporogenesis in inbred line of popcorn (Zea mays L.)

G. C. L. Ricci, Silva, N., Pagliarini, M. S., and Scapim, C. A., “Microsporogenesis in inbred line of popcorn (Zea mays L.)”, vol. 6. pp. 1013-1018, 2007.

Endogamy places genes for several characteristics in homozygosis, which include those related to meiosis causing abnormalities that may impair gamete viability. An original population (S0) of popcorn (CMS-43) produced by Embrapa Maize and Sorghum was self-pollinated for seven years, generating inbred lines (S1 to S7). Conventional studies of microsporogenesis revealed that meiotic abnormalities did not increase with endogamy.
