A male sterile pepper (C. annuum L.) mutant

  • Stefan Daskaloff


  1. 1.

    After treatment of dry seeds of red pepperCapsicum annuum L. with X-rays a male-sterile mutant was discovered in the M2.

  2. 2.

    The male-sterile mutant segregates in a ratio of 3.28:1 (χ2=3.148, probability 0.07).

  3. 3.

    After an alternative cultivation of male-sterile plants and of a variety with good combining ability relatively good fruit-setting and seed production was obtained.

  4. 4.

    Grafting of male-sterile scions to normal stocks does not affect the male-sterile phenotype.

  1. 1.

    Nach der Behandlung von trockenen Paprika (C. annuum L.)-Samen mit Röntgenstrahlen wurde in der M2 eine männlich-sterile Mutante entdeckt.

  2. 2.

    Die männlich-sterile Mutante spaltet im Verhältnis 3.28:1 (χ2=3,148, Wahrscheinlichkeit 0,07).

  3. 3.

    Bei einer alternativen Auspflanzung von männlich-sterilen Pflanzen und einer Sorte mit guter Kombinationseignung wurde ein verhältnismäßig guter Fruchtansatz und eine ausreichende Menge Samen erzielt.

  4. 4.

    Die Pfropfung männlich-steriler Reiser auf eine normale Unterlage beeinflußt den männlich-sterilen Phänotyp nicht.
