EXPRESSION OF NECROSIS IN THE HYBRIDS OF AMPHIPLOIDS TRITICUM DURUM-HAYNALDIA VILLOSA AND HORDEUM CHILENSE TRITICUM DURUM WITH SOME BREAD WHEAT CULTIVARS

Published on Oct 05, 2019 12:38 PM

Two amphiploids Triticum durum-Haynaldia vil/osa (AI) and Hordeum
chilense-Triticum durum (A2) were crossed reciprocally with 11 bread wheat accessions.
Out of 44 cross combinations, 18 crosses showed severe necrosis, 8 moderate and
the remaining 18 were found to have weak necrosis. The degree of necrosis in the
hybrids varied greatly due to multiple allelism of Nel and Ne2 genes.
