Observations on Inheritance of Male Sterility in Apricot
Male sterility is defined as the deviant condition in normally bisexual plants when no viable pollen is formed (Frankel and Galun, 1977). Male sterility has been exploited as an effective tool to aid hybrid seed production in many crops. Using this trait, seed producers can transform one inbred from a planned hybridization into a “female” line, thereby ensuring seed of hybrid origin on the male...
متن کاملThe Interaction of Nuclear and Cytoplasmic Factors in the Inheritance of Male Sterility in Maize.
ALE sterility in plants is of unusual interest since its inheritance is due M to a number of different mechanisms. In the early days of genetics a controversy existed as to the relative importance of the nucleus and the cytoplasm in inheritance. Many investigators believed the nucleus was all-important and relegated the cytoplasm to a non-essential role. That the cytoplasm did not always play a...
متن کاملDevelopment of cytoplasmic-nuclear male sterility, its inheritance, and potential use in hybrid pigeonpea breeding.
Pigeonpea [Cajanus cajan (L.) Millsp.] is a unique food legume because of its partial (20-30%) outcrossing nature, which provides an opportunity to breed commercial hybrids. To achieve this, it is essential to have a stable male-sterility system. This paper reports the selection of a cytoplasmic-nuclear male-sterility (CMS) system derived from an interspecific cross between a wild relative of p...
متن کاملINHERITANCE OF FERTILITY RESTORATION INVOLVING WILD ABORTIVE CYTOPLASMIC MALE STERILITY SYSTEM IN RICE (Oryza sativa L.)
Inheritance of fertility restoration was studied in crosses involving ten elite restorer lines of rice viz. BR6839-41-5-1R, BR7013-62-1-1R, BR7011-37-1-2R, BR10R, BR11R, BR12R, BR13R, BR14R, BR15R and BR16R and one male sterile line Jin23A with WA sources of cytoplasmic male sterility. The segregation pattern for pollen fertility of F2 and BC1 populations of crosses involving Jin23A indicated t...
متن کاملFemale and male sterility cause low fruit set in a clone of the `Trevatt' variety of apricot (Prunus armeniaca)
This study investigated ovule and anther structure of the `Trevatt Blue' variety of apricot (Prunus armeniaca) using bright field microscopy following reports of low fruit set. Ovules and anthers from fertile `Moorpark' and `Trevatt Knight' flowers were compared with those of the `Trevatt Blue'. In the `Moorpark' and `Trevatt Knight' ovules, all reproductive structures were present including em...
