| Abstract: | Summary The near-isogenic lines of the wheat variety Triple Dirk supposed to differ only for Vrn genes have been investigated for their similarity to Triple Dirk and for purity. The NILs were found to differ from Triple Dirk. It was also discovered that Triple Dirk and the NILs each exist of more than one genotype. It is recommended that each NIL is tested for its Vrn-genotype and purified. New sets of Vrn NILs can only be made with these checked NILs and with one-plant progeny of the newly used recurrent parents. |
