Seventeen parental clones were selected, from 9,000 plants,
on the basis of self-sterility, seed and forage yield potential using
phenotypic ratings, crude protein and chromogen content. The parental
clones were divided into two populations based on date of maturity.
Group I was intermediate in maturity and had nine parental
clones,...
A mathematical model of a differential thermal analysis (DTA)
system was formulated so that influence of the various physical parameters
on the DTA peak could be determined. The specific DTA apparatus
simulated had cylindrical sample holes drilled into a nickel
block considered to have a negligible thermal resistance, and the...
Response to heterosis for plant height, anthesis date, panicle
number, seed yield, and fall vigor rating was determined in a tall.
fescue group selected for diverse morphology, origin, and anthesis
date. Parents, single-cross progeny (SX), and first generation
selfed progeny (S₁) were included in the study.
Each experimental plot consisted...
The response of maturity, vigor, plant spread, plant height,
three forage harvest yields, and total forage yield to heterosis and
inbreeding was studied in tall fescue. Parent clones selected for
diverse anthesis date, origin, and morphology were separated into two
groups based on anthesis date, those having early maturity and...
