An impact of environment on segregation ratio of qualitative traits in maize

Abstract

The significant influence of environment was found on the segregation ratio in a dyhibrid inheritance in maize. Two possible causes are proposed for this segregation distortion: 1) environmental influence (selection) prior forming the gametes or/and 2) different preferential pairing in different environments. Further studies, however, on other self or cross-pollinated plant species, and with different traits are needed to better understand this phenomena.

Značajan uticaj spoljašnje sredine na segregacioni odnos je utvrđen kod dihibridnog nasleđivanja kod kukuruza. Dva moguća uzorka segregacione distorzije su: 1) uticaj spoljašnje sredine (selekcija) pre formiranja gameta ili/i 2) različita preferencijalna ukrštanja u različitim sredinama. Dalja istraživanja, na drugim samooplodnim ili stranooplodnim biljnim vrstama i sa različitim svojstvima su potrebna da bi se ovaj fenomen bolje razumeo.
