“…These values show that there is a superior dominance in nonadditive gene effects. CHAUDHARY et al (2015) reported that the non-additive gene effects were predominant in green plant regeneration, while the additive gene effects were a presence in callus formation. EL-HENNAWY et al (2018) informed that additive gene effects on variability observed in the androgenic process contributed more than non-additive gene effects.…”

“…In androgenesis, chromosomal doubling occurs at very early stages of embryogenesis, and the resulting plants are then completely doubled and fertile. Compared to plants treated with colchicine, spontaneous DH plants produce much more seed even when first obtained and can rescue a generation for seed multiplication before phenotyping for quantitative traits (CHAUDHARY et al, 2015). When the combining ability effects calculated for the number of spontaneous DH plants are examined, it is seen that four parents in the F1 generation and five parents in the F2 generation have a positive GCA effect (Table 5).…”

The aim of this study was to investigate the gene effects that play a role in the inheritance of the anther culture response of the F1 and F2 populations obtained from the hybridization between the seven doubled haploid (DH) wheat line and four bread wheat cultivar using line × tester method as well as, to determine suitable parents and promising hybrids. Eleven parents and their twenty-eight hybrid combinations were examined for androgenic properties related to anther culture response such as the number of callus, green, albino, haploid, spontaneous DH and fertile plants. The obtained data were evaluated by the combining ability analysis calculated using the line × tester method and by estimating the heritability degrees. According to the results, for all traits examined, the non-additive gene effects were found as significant and narrow sense heritability at a low level. Significant combining ability effects have been identified for some parents and hybrids regarding traits examined. DH19, DH22, and Harmankaya-99 have been identified as suitable parents to develop the androgenic traits, while crosses formed between them have been determined as promising. A total of 444 plants (142 F1, 302 F2) were transferred to the greenhouse from the plants obtained from the anther culture, and 205 (68 in F1, 137 in F2) were fertile. Ninety-three of the fertile plants were obtained from

“…These comprise of (1) difference in cell cycle timings between the parents (Sanei et al, 2011), (2) parent‐specific centromere inactivation (Finch, 1983), (3) non‐synchronous nucleoprotein synthesis (Bennett et al, 1976) and (4) chromosomal degradation by host‐specific nucleases (Davies, 1974). Wide hybridization‐based HI methods have been widely employed since it creates genetic variation and broadens the genetic base of the crops (Chaudhary et al, 2015). Till now, haploids have been produced in several important crop species such as barley, wheat, potato, oats and tobacco using wide hybridization (Dunwell, 2010; Hougas & Peloquin, 1958; Kasha & Kao, 1970; Laurie & Bennett, 1988; Rines & Dahleen, 1990).…”

Strategies and prospects of haploid induction in rice (Oryza sativa)

Being a model crop as well as a staple food crop, rice possesses a conspicuous position in plant sciences. Doubled haploid (DH) breeding in rice offers multiple advantages over conventional methods via accelerating the process of pure lines development. For ages, several methods have been devised for haploid production in rice. In vitro‐based methods have demonstrated their potential in DH production, but these methods are further impeded by stringent requirements and restricted to few species. Further, unlike maize, the in vivo DH breeding technology is still impractical in rice. Recent findings of the key molecular players behind the haploid induction (HI) trait in maize and rice have shown their potential in rice improvement programmes. In this review, we have discussed different strategies of HI in rice particularly focusing on recent progress made for developing haploid inducer stock (HIS) by employing both conventional and modern approaches. It also focuses on future implications of HIS so that it can be incorporated in the pipeline of modernized rice breeding.

“…Compared to conventional breeding methods, the numerous haploid breeding procedures have tremendous relevance and practical utility. It takes one year to produce completely homozygous plants using in vitro haploid culture or intergeneric hybridization with maize and cogon grass (Imperata cylindrica) and chromosome doubling using colchicine, but conventional breeding takes 7-8 years to isolate stable lines from the clines (Chaudhary et al, 2015). We don't need to establish vast populations of haploid plants because selection based on gametic frequency can be done.…”

The study was undertaken to evaluate the relative efficiency of doubled haploid production methods following the chromosome elimination approach utilizing maize- and Imperata cylindrica- mediated systems. For doubled haploid production, triticale x wheat derived recombinants in different generations comprised of F1, F2, F3, F4, BC1F1, BC1F2, BC1F3, BC1F4 and BC2F3 were used. The haploid embryos were cultured in the MS medium with different mineral constituents and hormones. All the generations responded for different haploid induction parameters following maize- and Imperata cylindrica- mediated systems. Advanced generations responded better than early generations for haploid induction through both systems. All the haploid induction parameters, Imperata cylindrical- were performed significantly better than maize.
