Combining ability of grain weight per spike in spring barley varieties
Keywords:
spring barley; combining ability; grain weight per spikeAbstract
The study was conducted during on the parents and F1 hybrids of spring barley obtained from full diallel combination. For parents were used Scarlett, Fink, Barke, Zernogradskij 73, Bitrana and line - 3717С-60. The general and specific combining ability of parental components were studied for the indicator grain weight per spike. It was found that variety Scarlett has good combining ability and can be used in crosses to obtain hybrids of high grain weight per spike. The SCA variances were high for parents Zernogradskij 73, Fink and Barke. They are not reliable in combinatory selection as they are also the varieties with the lowest phenotypic manifestation of the trait.
