Transgressive segregation in inter and intraspecific crosses of barley

摘要: Six populations of F2-derived lines barley and their parents were evaluated for heading date, plant height, grain yield, bundle weight, harvest index in a replicated experiment the field. These data used to estimate minimum number effective factor pairs segregating each trait, favorable factors contributed by parent cross, frequencies magnitudes transgressive segregates. Heading controlled three four pairs, whereas yield weight five or more. All H. spontaneum strains our study one more useful genes traits, index. Therefore, it seems that can be source quantitative especially which could incorporated into varieties readily backcrossing. Transgressive segregates interspecific crosses may provide basic materials improving productivity cultivated varieties.
