Pati K., A. Das Munshi and T. Kanti Behera (2015): Inheritance of gynoecism in cucumber (Cucumis sativus L.) using genotype gbs-1 as gynoecious parentGenetika, Vol 47, No. 1, 349-356. The inheritance pattern of gynoecious sex expression in cucumber was studied by utilizing a gynoecious line (GBS-1) and two monoecious lines (Pusa Uday and Punjab Naveen). Crosses were made between gynoecious line (GBS-1) and monoecious lines (Pusa Uday and Punjab Naveen). The F1 and F2 population along with parental lines were evaluated to study the inheritance of this trait. All F1 hybrids showed gynoecious sex in both crosses and in the F2 generation, the observed distribution of plant phenotypes fitted the expected mendelian ratio of 3 (gynocious plant) : 1 (monoecious plant). The segregation of plant sex types suggested monogenic dominant control of gynoecious sex form in cucumber using genotype GBS-1 .

Inheritance of gynoecism in bitter gourd (Momordica charantia L.).

The inheritance of sex expression in cucumber (Cucumis sativus) and other cucurbits is well documented; however, the genetics of female sex (gynoecism) expression in bitter gourd (Momordica charantia) has not been described. Inheritance of gynoecism in bitter gourd was studied in a 100% gynoecious line (Gy263B). The F(2) and testcross segregation data revealed that gynoecism in Gy263B is under ...

Cloning of a cDNA for a 1-aminocyclopropane-1-carboxylate synthase that is expressed during development of female flowers at the apices of Cucumis sativus L.

In cucumber (Cucumis sativus L.) plants, it has been reported that a high correlation existed between the evolution of ethylene from the apices and the development of female flowers. We isolated three distinct cDNA encoding 1-aminocyclopropane-1-carboxylate (ACC) synthase from cucumber. Among of these, only CS-ACS2 mRNA was detected at the apices of gynoecious cucumber in which female flowers w...

Ethylene: A Natural Regulator of Sex Expression of Cucumis melo L.

Sex expression in cucumber (Cucumis sativus L.) and muskmelon (C. melo L.) was correlated with endogenous ethylene production. Plants of gynoecious (all female) sex types of the two species produced more ethylene than monoecius (male-female) plants. C. melo plants of a gynoecious sex type that normally produce only pistillate (female) flowers, when grown with hypobaric ventilation to facilitate...

Expression of multiple AGAMOUS-like genes in male and female flowers of cucumber (Cucumis sativus L.).

Members of the MADS-box gene family control reproductive development in higher plants. In cucumber, floral development exhibits several interesting features related to a genetically determined sex-expression mechanism, that affects the differentiation of male and female flowers. In this study, three cDNA homologues of the homeotic gene AGAMOUS have been cloned from early-stage floral buds of Cu...

Contents and recovery of gibberellins in monoecious and gynoecious cucumber plants.

Diffusates from seedlings and root exudates from 6-week-old plants of a monoecious line of cucumber, Cucumis sativus L., contained considerably higher levels of gibberellin-(GA-) like substances than did those from plants of an isogenic gynoecious line. Most of the GA-like activity was found in a chromatogram region typical of GA(1) and GA(3); some activity, particularly in root exudates, appea...
