Gamete selection in corn

This study was conducted at the Texas A&M University, College Station, Texas, from 1965 to 1967. The variable gametic sources were three complex hybrids: [line break] A. (FYD-2 X YS-2) X Indian Chief [line break] B. (FYD-2 X YS-2) X (Jarvis X Indian Chief) [line break] C. (FYD-2 X YS-2) X Jarvis [line break] The tester and the elite inbred line, Tx508 and Tx403, respectively, were of high combining ability. The single cross of the tester and the elite inbred line (Tx508 X Tx403) was used as the check in the evaluation experiment. The objectives of this study were to evaluate the suitability of a monogametic tester, to estimate the frequency of superior gametes in the three different populations, and to initiate a breeding program designed to improve an elite inbred line (Tx403). The use of an inbred line as a tester in gametic selection eliminated any possibility of introducing alien variability in the test-cross progenies. Although the use of a monogametic tester prevented the evaluation of gametes for general combining ability, it was felt that any general combining ability comparisons based upon a genetic ally variable tester would be suspect since the source of genetic variability could not be identified. ..
