“…However, genes affecting different anther culture traits are not necessarily located close to each other in the genome. According to QTL mapping results, more than twelve loci on 9 chromosomes of maize (Beckert 1998, Marhic et al 1998) and eight loci on seven chromosomes of rice (He et al 1998) are estimated to control the androgenic pathway.…”

“…wheat (Hu 1997), barley (Ouédraogo et al 1998) and rice (Oryza sativa L.) (He et al 1998). In maize (Zea mays L.), anther culture results are improved by producing DH plants from different germplasms and intercrossing them (Marhic et al 1998). Anther culture ability has been sought from more distant genepools: enhancement was obtained in recalcitrant indica rice by crossing with responsive japonica rice (Omar Faruque et al 1998), and in rye (Secale cereale L.), by introgressing sections of the wheat genome through creating rye-wheat addition lines (Martinez et al 1994).…”

A study was carried out to improve anther culture ability of the non-responsive cultivated oat, Avena sativa L. cv. Puhti by introgressing favourable alleles from the responsive wild red oat, Avena sterilis L. acc. CAV 2648. Anther culture ability of these parental lines and F 2 progenies of their cross and two backcrosses was tested. Genotype effects were significant on all anther culture traits measured. The number of anther culture derived embryo-like structures was highest in acc. CAV 2648, and the number of green regenerants from the Puhti × CAV 2648 progeny. Anther culture response was greatly reduced in backcross progeny and was least in cv. Puhti. Random amplified polymorphic DNA (RAPD) was used to test for marker associations with oat anther culture traits in a population of 38 F 2 progenies. Two RAPD markers were putatively associated with improved production of green regenerants (one derived from acc. CAV 2648 and the other from cv. Puhti). One marker putatively associated with decreased albino plant regeneration (derived from acc. CAV 2648). These markers might be useful for selecting alleles for better anther culture ability among progeny of planned crosses. In addition, three markers, derived from acc. CAV 2648, were putatively associated with decreased anther culture response rates.

“…In maize, Thomson (1954) and Chase (1974) found about the same variation among spontaneous DH as among selected and unselected conventional inbred lines evaluated in hybrid combinations for grain yield. Murigneux et al (1993) and Marhic et al (1998) did not find large differences between DH lines derived by anther culture and lines from pedigree selection or SSD evaluated for their per se value or their testcross performances. Until now, few studies have considered the genetic variance from DH lines derived by in situ gynogenesis which appears to be the most successful technique of DH derivation.…”

Progress made in the in situ gynogenesis technique since 1990 now allows production of a high number of maize (Zea mays L.) doubled-haploid (DH) lines. The aim of the study was to compare DH lines versus selfing lines for testcross performance. DH and single-seed descent (SSD) lines were produced from random S 1 progenies of a broad-base population. For grain yield, kernel moisture, plant height, ear height and leaf length, the three population means were similar. Except for kernel moisture, the genetic variance of DH lines was nearly twice as high as the genetic variance of S 1 families, as expected. On the other hand, genetic variance among SSD lines was only 1.5 times higher than the genetic variance of S 1 families. This lower variance could be due to a selection bias in the method of production of SSD lines. However, for all traits, heritability of SSD or DH lines was higher than heritability of S 1 families. Epistasis effects in DH progenies were not significant. The consequence was a high correlation between S 1 testcross progenies and DH or SSD testcross progenies, meaning that the S 1 testcross value can be used to select the best families from which DH lines will be extracted. As a whole, the observed variation in DH lines appeared to be more in accordance with the observed variation among S 1 families than with the observed variation among SSD lines.

“…Beaumont et al (1995) found that many QTL for induction of embryos during anther culture were also in the same chromosomal regions as genes that have viviparous mutant alleles, providing further evidence for the prominent role of ABA (or its absence) in the induction of embryos in vitro. Also, Marhic et al (1998) observed that selection for anther culture response in maize resulted in a signiWcant increase in the number of tillers per plant, which may have resulted from changes in ABA concentrations or sensitivities. It is not clear from these studies what exact role ABA has; the detection of so many QTL in close association with genes that have viviparous alleles does not necessarily mean that induction of embryos results from the suppression of ABA, and could be the opposite, since the alleles from highly responsive inbreds have not been speciWcally identiWed and characterized.…”

Quantitative trait loci for callus initiation and totipotency in maize (Zea mays L.)

et al. 2006

Induction of embryogenic callus in culture is an important step in plant transformation procedures, but response is genotype speciWc and the genetics of the trait are not well understood. Quantitative trait loci (QTL) were mapped in a set of 126 recombinant inbred lines (RILs) of inbred H99 (high Type I callus response) by inbred Mo17 (low Type I callus response) that were evaluated over two years for Type I callus response. QTL were observed in a total of eleven bins on eight chromosomes, including eight QTL with main eVects and three epistatic interactions. Many of the QTL were mapped to the same or bordering chromosomal bins as candidate genes for abscisic acid metabolism, indicating a possible role for the hormone in the induction of embryogenic callus, as has previously been indicated in microspore embryo induction. Further examinations of allelic variability for known candidate genes located near the observed QTL could be useful for expanding the understanding of the genetic basis of induction embryogenic callus. The QTL observed herein could also be used in a marker assisted selection (MAS) program to improve the response of agronomically useful inbreds, but only if the resources required for MAS are lower than those required for phenotypic selection.
