D-genome of common cultivated wheat has been contributed by
A. T. monococcum
B. T. durum
C. T. timophivi
D. Ae squarosa
Answer: Option D
Solution(By Examveda Team)
D-genome of common cultivated wheat has been contributed by Ae squarosa.The D genome of allohexaploid bread wheat (Triticum aestivum, 2n = AABBDD) is the least diverse of the three wheat genomes and is unarguably less diverse than that of diploid progenitor Aegilops tauschii (2n = DD).
Aegilops tauschii (synonyms Aegilops squarrosa, Triticum tauschii), is a wild goatgrass that was one of the parent species of bread wheat.
