Are parthenocarpy and apomixis different phenomena? Discuss their benefits.
- Yes non-fertlised fruit development and apomixis both are different methods.
$\Rightarrow \quad$ Importance of non-fertilised fruit development :
(i) The method of producing fruits without fertilisation of ovule is called non fertilised fruit development. This method is used for development of seedless fruits commercially eg. Banana, Grapes. (ii) This method is more useful in fruit juice industries.
Importance of Apomixis : $(i)$ During Apomixis neither chromosomes separate nor connect. So characteristics are maintained till many generations. $(ii) $ Commercial hybrid production can be easily explained because there is no need for isolation process for either maintaining parent offspring or to separate first generation.
$(iii)$ Adventive embryoni is used for typical root mass and to produce virusless species
The best example of polyembryony is
Which of the following process is helpful in hybrid seed production:
In agamospermy, the embryo sac is diploid because it is formed without meiosis. Such embryo sac may develop from
What is polyembryony and how can it be commercially exploited ?
Choose the correct option from the following statements.
$I$. Apomixis is form of asexual reproduction which mimics sexual reproduction.
$II$. In Apomixis seeds develop either from diploid egg cell or from cells of nucellus.
$III$. Seeds collected from hybrids plant maintain hybrid character for a longer times.
$IV$. In Apomixis, there is segregation of characters.
