Summary
Fifteen backcross derived, six-rowed isogenic barley (Hordeum vulgare L.) lines with the genotype vvii, nine in a six-rowed background, and six in a two-rowed background, were evaluated over 3 years for pedicel length and lateral and central kernel weight.
Within the six-rowed and two-rowed backgrounds there were significant differences between isolines for all three characteristics studied. The lateral kernel weights of the six-rowed isolines were approximately half of their central kernel weights. Isolines with club heads had signicantly longer pedicels and significantly lower lateral and central kernel weight than lax headed types. A significant negative correlation was found between pedicel length and lateral kernel weight for the 15 isolines and within the six-rowed background, indicating that as pedicel length increases, lateral kernel weight tends to decrease.
We recommend that breeders making selections of six-rowed segregates from two x six-rowed crosses should select against pedicellate (vvii) laterals.
