“…Murdock (1993) found that, in an autotetraploid, segregation of the trait approached a chromosomal inheritance pattern, suggesting a close linkage to the centromere and/or barriers to crossing over in the autotetraploid. Thus, there is no indication that an ms maintainer line would be genotypically unstable due to the occasional production of duplex male-fertile plants (Love et al, 1986). Murdock (1993) and Zhang et al (1993 found no indication of linkages with seedling characters Sp, dg, and ja.…”

“…Fertile male flowers do occur very late in the development of the mutant and partially male fertile glabrous lines can be developed (Rhodes, 1991). Love et al (1986) introduced the gene into tetraploids, but the reduction of female reproduction as well as fruit quality and yield associated with this pleitropic mutant was never eliminated. A spontaneous genic male-sterile (ms) from China (Xia et al, 1988) is stable for male sterility with minimal pleitropic effects, if any.…”

“…Glabrous leaves and malesterility characters have never been separated and are inherited as a single recessive nuclear gene, suggesting close linkage or a pleiotropic effect of the locus involved. The possibility of rapid identification of male-sterile plants at the seedling stage via the glabrous phenotype generated considerable interest in introducing the ms g gene into diploids and even tetraploids for hybrid seed production (Love et al, 1986). However, there has been little commercial application because the ms g gene not only anthracnose [Colletotrichum lagenarium (Pass.)…”

This research was conducted to develop genic male-sterile lines of watermelon (Citrullus lanatus Matsum & Nakai) homozygous for the juvenile albino (ja) seedling marker. Male-sterile plants (msms) of the genic male-sterile line G17AB were crossed with a Dixielee plant that was heterozygous for the ja locus. Male-fertile, juvenile albino recombinants of the F2 progeny were self-pollinated, resulting in F3 progeny. The male-sterile normal green recombinants of the F2 progeny were crossed with an F1 hybrid plant with genotype MsmsJaja, and three populations (93JMSB-1, -2, and -3) were obtained from these crosses. Juvenile albino recombinants were confined to 93JMSB-1. Of the juvenile albino plants of 93JMSB-1, male-sterile plants were sib-crossed with male-fertile plants, resulting in 93JMSB-1-1. Progeny of 93JMSB-1-1 was homozygous for ja and segregated for ms in a 127 male-sterile: 128 male-fertile ratio, fitting a 1:1 ratio. The male-sterile juvenile albino plants of F3 were crossed with male-fertile juvenile albino plants of 93JMSB-1, resulting in 93JMSF3-1 and -2. Plants 93JMSF3-1 and -2 were homozygous for ja but segregated for ms at 10 male-sterile: 13 male-fertile and 15 male-sterile: 19 male-fertile for 93JMSF3-1 and 93JMSF3-2, respectively, fitting the 1:1 ratio. These three genic male-sterile lines with the ja seedling marker provide valuable germplasm for introducing ms and ja genes into diverse genetic backgrounds and for studying cross-pollination and gene flow in watermelon populations.

“…Pleiotropic effects of male sterility genes have been reported to be helpful in the recognition of male steriles at the seedling stage in Gapsicum (MESHRAM and NARKHEDE 1982) and Gitrullus (LOVE et al 1986). They are recognized hy excessive vegetative growth in Gapsicum and by glabrous leaves in Gitrullus.…”

“…The female lines thus obtained, on crossing to a diploid, produce seedless triploids. The reduced fruit quality and seed set in male sterile tetraploids is being improved iti order to make the scheme commercially feasible (LOVE et al 1986). …”

The possible applicatiotis of genie male sterility (CMS) in plant breeding are reviewed and discussed. The basic contribution of CMS is that it provides a means of genetic emasculation which can be applied for the massive production of hybrids. There are two main fields of application: (1) the production of hybrid varieties and (2) inter-and intraspecific hybridization and back-crossing programmes for the introduction of genetic variation into crop varieties. Several schemes have been proposed for using CMS in hybrid breeding in different crops. These are discussed under four headings: genetic methods, c\'-togenetic methods, temporary restoration of fertility and manual pollination. The application of CMS in hybridization intended for the introduction of alien genes is discussed as well as factots alfeeting the pollination of genie male steriles.
