“…The influence of genotype on in vitro growth and differentiation patterns has been reported in a number of crop plants (Henry et al, 1994). The genetic basis of in vitro response has been analyzed in several plant systems including alfalfa (Wan et al, 1988;Kielly and Bowley, 1992;Crea et al, 1995), barley (Foroughi-Wehr et al, 1982;Komatsuda et al, 1989;Özgen et al, 2005), sunflower (Encheva et al, 2004), cotton (Gawel and Robacker, 1990), maize (Nesticky et al, 1983;Tomes and Smith, 1985), petunia (Dulieu, 1991), rice (Quimio and Zapata, 1990;Abe and Futsuhara, 1991;Yan et al, 1996;Kuroda et al, 1998), rye (Rakoczy-Trojanowska andMalepszy, 1993), tomato (Frankenberger et al, 1981;Koorneef et al, 1987;Soniya et al, 2001), wheat (Lazar et al, 1984;Ou et al, 1989;De Boyser et al, 1992;Lange et al, 1995;Dornelles et al, 1997;AbdelHady, 2006;Ozbay and Özgen, 2010), eggplant (Chakravarthi et al, 2010) and pearl millet (Mythili et al, 1997). Nesticky et al (1983) noted significant reciprocal effects in the basic of combining ability and high values of reciprocal effects in corn tissue culture.…”
