University and Research Centre with the objective of how diversity with the
composite cross populations of winter wheat evolves over the years? And which
traits show most diversification? Four different aged composite cross population,
one CCP-extra population and one pure line winter wheat cultivar were evaluated
using a randomized complete block design with three replications. Significant
differences were observed for the traits plant height, flag leaf spike length
and width of the leaf next to the first leaf. For plant height and flag leaf
spike length, all CCPs have higher values for the diversity index. There were
no significant differences between the CCPs in values for the Shannon-Weaver
diversity index, H'. Genotypes showed highly significant differences for the
SD within plots for the traits plant height (p<0.001), flag leaf spike distance
(p<0.001), width of the 1st leaf next to the 1st node (p<0.008) and width
of the flag leaf (p<0.001).]]>Acquaah, G.,20071st Edn.,Pages: 584Pages: 584Bechere, E., G. Belay, D. Mitiku and A. Merker,1996124165172Busch, R.H., J.C. Janke and R.C.
