INTRAPLANT MORPHOLOGICAL VARIATIONS IN GRASSES

Clonal progenies were developed from individual nodal segments of bromegrass, cormlets of timothy, and secondary basal buds of sorghum. The parent plants were morphologically unstable or chimeral and occurred in either hybrid or inbred populations. Intraplant clonal progenies usually continued to be unstable through the second clonal generation. Marked deviating types occurred within clonal rows. Intraplant comparisons were made of inflorescence characters and seed-set following open-pollination of unstable plants from inbred lines of smooth bromegrass. Significant differences occurred between characters in panicles from different parts of the same plant.
