Q838
The sources of male sterility include
A.
Spontaneous mutations
B.
Induced mutations
C.
Interspecific crosses
D.
None of these
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
The sources of male sterility include failure of another dehiscence, nonfunctional pollen grains, etc.But it is not caused by Spontaneous mutations, Induced mutations, and Interspecific crosses.
Male sterility (CMS), a condition under which a plant is unable to produce functional pollen, is widespread among higher plants.
Male-sterility plants provide crucial breeding tools to harness hybrid vigor, or heterosis, in hybrid crops and also provide important materials to study stamen and pollen development and cytoplasmic-nuclear genomic interactions.
