Cytoplasmic Sterility

The effect of four isogenic cytoplasmic types, normal, Salvador, Texas, and Charrua (the latter three causing male sterility), on the process of chiasma formation has been studied using two different maize hybrids. The cytoplasmic male sterility determinants have been shown to reduce the rate of interstitial exchanges per nucleus and per bivalent and the frequency of univalents. Increased variation between plants and relative stability of the intercellular variation within a plant have been observed for the parameters studied. It is concluded that the determinants of cytoplasmic sterility lower the probability of additional exchanges (relative to the obligate one) and reduce the frequency of premature disruption of one-exchange chromosome associations.Key words: maize, chiasma frequency, male sterile cytoplasm, univalent formation, genotype × cytoplasm interaction.

Hybrid Development

Among the different mechanism of male sterility operated in the Brassica group crop. Cytoplasmic male sterility mechanism is most suitable for hybrid development in cauliflower because here the curd (intermediate stage) is an edible part of the cauliflower. Further, there is no requirement of restorer line in this case as required in other seed crop. For the multiplication and maintenance of the different lines (A line and B line), sib mating and selfing is not always desirable. In fact, in such situation doubled haploid production through microspore culture is a more appropriate mechanism. Apart from this, the undesirable effect of integration of male sterile cytoplasm can be mitigated by adopting the repeated back crossing, through chloroplast substitution or somatic hybridization mechanism.

Method Analysis

AbstractThe genetic diversity of 43 male sterile and low fertility Citrus accessions, as well as 13 fertile ones, were assessed using simple sequence repeat markers (SSRs). Thirty-five polymorphic alleles were generated from eight primers (on average 4.4 alleles per primer). Cluster analysis was performed via unweighted pair group method analysis (UPGMA) using the NTSYS-pc version 2.10. The results showed that the accessions could be classified into three groups: cultivars of mandarin were classified into group 1; those of sweet orange, grapefruit, ponkan or tangor into group 2; and Microcitrus with male sterile cytoplasm into group 3. Cluster analysis also revealed that Satsuma mandarin was more closely related to Bendiguangju mandarin than to Zaoju, Mankieh or Huangyan Bendizao tangerine. The present study on genetic diversity of male sterile and low fertility Citrus will provide useful information for further collection, preservation and utilization of this plant.
