Triatoma maculata, the Vector of Trypanosoma cruzi, in Venezuela. Phenotypic and Genotypic Variability as Potential Indicator of Vector Displacement into the Domestic Habitat

The use of cytoplasmatic male-sterility in maize seed production contributes to increase economical efficiency and to obtain great genetical seeds. Through this theme one has followed the realization of a comparative study between some hybrids obtained to Turda on C and T cytoplasm their homologues, developed with normal and through the castration of the maternal parents. The researches aimed mainly the phenotypic and genotypic variability of the hybrids, the degree of male-sterility and the capacity of production, in phytotechnic conditions in different densities.

Phenotypic And Genotypic Variability

SUMMARYTwo years study was made on variability in 42 indigenous and exotic varieties of sesame. With very few exceptions, highly significant differences were found between the varieties for the 15 characters investigated. A wide range of phenotypic and genotypic variability was exhibited by all characters except oil, protein and moisture, and 9 out of 15 characters gave heritability estimates exceeding 80 per cent. To relate heritability values to other genetic parameters, a ‘rank procedure’ showed that the characters followed one another in a definite order.

Phenotypic And Genotypic Variability

Cytoplasm male sterility is used for producing hybrid corn seeds by reason of the economic efficiency and is also advantageous for genetic purity of seeds. Three types of male sterility cytoplasm in maize are used as cms maternal parents to produce hybrids: cms-C, cms-S. cms-T. Through this theme one has followed the realization of a comparative study between some hybrids obtained to Turda on C and T cytoplasm their homologues, developed with normal and through the castration of the maternal parents. The researches aimed mainly the phenotypic and genotypic variability of the hybrids, the degree of male-sterility and the capacity of production, in phytotechnic conditions in different densities
