Development of innovative techniques and principles that may be used as models to improve plant performance. Technical progress report, February 1, 1991--January 31, 1992
Methods and techniques for transferring germplasm from wild to cultivated species are being developed. The transferred germplasm is being shown to be valuable in plant breeding and in cultivar development. Forty cytoplasms from the wild grassy subspecies monodii (primary gene pool) of Pennisetum glaucum are being tested for cytoplasmic effects on morphological characteristics and forage yield. A`-genome chromosomes from P. purpureum (secondary gene pool) have been transferred to cultivated pearl millet. The A`-chromosome derived lines have been developed into excellent male pollinator lines to produce a new high quality, high yielding grain hybrid for the US. Significant progress is being made in transferring the genes controlling apomixis (to produce true-breeding hybrids) from the tertiary gene pool to cultivated pearl millet. Backcross-4 plants are more pearl millet-like and reproduce by apomixis. New genome combinations have been produced in the apomixis genes transfer program which demonstrate the impact of apomixis on speciation and evolution.
