Description
Kleingrass (Panicun coloratum L.) populations from 2 germplasm sources previously subjected to 3 cycles (C3) of recurrent selection for increased seedling shoot fresh weight were compared with the base (Co') populations for shoot growth, root growth, seed weight and seed starch. content, Shoot weight (fresh and dry) was significantly greater in c3: than in C0 when evaluated in the environment In which selection was: practised (growth chamber). Large significant differences in fresh and· dry weight between C0 and C3 populations were also observed in I field. experiment; with smaller, non-significant differences in a second field· experiment. Seed weight was not significantly increased by selecting for increased shoot weight. However, starch content of the seed was significantly increased .. Number of adventitious roots was not significantly affected by recilrte/it selection for shoot weight, but adventitious roots were significantly longer in one of two experiments.
