Development of new peanut (Arachis hypogaea L.) cultivares over the past 40 years has more than doubled yield potential. The purpose of this paper is to identify and evaluate the physiological changes made in the course of this varietal improvement that are responsible for the great increase in yield potential. Weekly harvests of large samples of four Florida cultivars, a Spanish peanut type and one soybeans Glycine max (L.) Merr.) cultivar gave the information needed to show the progressive changes in dry weights of all plant parts throughout the growing season. Other weekly samplines and observations gave numbers of pegs, flowers, and fruits as well as fruit weights, root length, shoot length, and leaf areas. Quantitative estimates of the physiological factors responsible for the dry eight differences were made by computer simulation using the Penutz model. Differences in three physiological processes explain most of the yield variation among the five peanut cultivares, the partitioning of assimilate between vegetative and reproductive parts, the length of the filling period, and the rate of fruit establishment. Of these, the partitioning of assimilate had the greatest effect on fruit yield. Estimates of partitioning to fruit ranged from 41% in the first cultivar released to 98% in the most recently released cultivar. Crop growth rates did not differ significatly among peanut cultivars but all were much higher than the crop growth rate of soybenas. |
