Summary
-
1.
After treatment of dry seeds of red pepperCapsicum annuum L. with X-rays a male-sterile mutant was discovered in the M2.
-
2.
The male-sterile mutant segregates in a ratio of 3.28:1 (χ2=3.148, probability 0.07).
-
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.
Grafting of male-sterile scions to normal stocks does not affect the male-sterile phenotype.
Zusammenfassung
-
1.
Nach der Behandlung von trockenen Paprika (C. annuum L.)-Samen mit Röntgenstrahlen wurde in der M2 eine männlich-sterile Mutante entdeckt.
-
2.
Die männlich-sterile Mutante spaltet im Verhältnis 3.28:1 (χ2=3,148, Wahrscheinlichkeit 0,07).
-
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.
Die Pfropfung männlich-steriler Reiser auf eine normale Unterlage beeinflußt den männlich-sterilen Phänotyp nicht.
