Book Description
If the production of hybrids is considered as the future of maize breeding, the primary emphasis in an improvement program will be directed toward the most rapid and efficient means of effecting improvement in the population available to the breeder, and for the development of efficient methods for obtaining inbred lines and identification of superior hybrids from the improved breeding populations, Most maize varieties have shown considerable additive genetic variance to be present for grain yield, suggesting that intrapopulation selection would result in measurable improvement of these populations. The objective of this study was to evaluate 14 cycles of mass selection for yield improvement in an open-pollinated variety of maize, Krug, and to describe thecorrelated eresponses with other plant and ear traits. The evaluation was conducted at five Iowa locations (Kanawha, Ames Agronomy Research Center. Ames Hinds Farm. Ankeny, and Martinsburg), but because of a severe drought stress at the Ames Agronomy Research Center in 1977, this location was considered too poor to be harvested. The results from the combined analyses of variance over tje four locations showed significant differences among entries for all traits but number of plants per hectare; however, most of the differences were attributed to the check varieties. The average yield for the original and successive cycles of mass selection were not consistent for the different groups of entries. Mass selection was not effective for improving the yield (...).
