Precision requires that the term self-pollination be restricted to those plants that accomplish pollination without an external pollinator. The language you choose must correspond to the language of the term you have entered. George, BB, Barbados, W.

The lowest frequency of superior offspring in relation to average parents was observed in the segregation for stalk weight. Apomixis in higher plants. For the inbreeding depression occurrence, besides heterozigosity in the locus, plahtas should be dominance and or epistasis in the character control.

Soluble solids means were obtained by direct sugarcane juice readings in ten and eight randomly chosen stalks from self and autofecundackon respectively. Inbreeding depression estimates allow the inference of population genetic structure and predominant gene action in the genetic control of characters. A hand refractometer was used to determine the rate of soluble solids in the cane juice.
