“…Dry matter accumulation per unit time is growth rate. Much growth rate studies in small grains have focused on preheading growth (Helsel & Frey, 1981;Jalani et al, 1981;Takeda & Fery, 1976, 1977Takeda et al, 1979), but several studies have indicated that postheading growth rate should be investigated more thoroughly by small-grain researchers. Postheading growth rate and dry matter accumulation have been positively associated with grain yield in oats (Avena sativa L.) (Brinkman & Rho, 1984), and wheat (Triticum aestivum L.) (Austin et al, 1980).…”

Preheading and postheading growth rates, grain yield and other traits were evaluated in 5 cultivars grown at 2 sites in Wisconsin (Madison in 1985 and Arlington in 1985 and 1986). The experimental design was a randomized complete block with 4 replications. Significant differences were observed among cultivars in preheading and postheading growth rates and DM accumulation. Correlation coefficients for growth rate at maturity and postheading growth rate with grain yield were highly significant (r = 0.93 and 0.79, respectively). Robust produced the highest grain yield (363.1 g/msuperscript 2). There were significant differences among cultivars in harvest index which was also correlated with grain yield (r = 0.41). Thus, differences in preheading and postheading growth traits among barley cultivars are highly associated with yield and may be useful for grain yield improvement.

“…EAGLES & FREY (1974) and SAAD EL DIN (1979) showed that an index that included two or more traits was more efticient in selecting for grain yield of oats (Avencl sativa L.) than was selection for grain yield itself. HELSEL (1980) used the general concept that Grain yield = Growth rate x Growth duration x Harvest index in several direct and indirect selection schemes l Journal Paper No. J-10772 of the Iowa Agric.…”

“…The smaller population means found in W populations due to the effects of A. sterilis germplasm were not unusual; however, the small genetic variances for G YD, SYD, and GR were unexpected (Tables 8, 13, 18). A. sterilis germplasm has been described as a source of variability for genes con trolling GYD (Lawrence and Frey, 1975;Frey, 1976) and GR (Takeda and Frey, 1976;Helsel, 1980). In this study, W populations had genetic variances less than C populations for GR and SYD and equal to CI for GYD.…”

Reduced genetic variability within the cultivated gene pools of crop species is a phenomenon of contemporary agri cultural systems. In extreme circumstances, this reduction can suspend progress from selection or precipitate catastrophies such as the Irish potato famine (Salaman, 1949). Con sequently, the introgression of germplasm from exotic, wild, or weedy relatives is an integral part of many plant breeding programs (Harlan, 1976; Hawkes, 1977). In the broadest sense, introgressive hybridization is the incorporation of germplasm from one isolated population into another of the same or a related species (Heiser, 1973). It is believed to play an evolutionary role, and introgression between sympatric domesticated plants and their wild relatives is common (Stebbins, 1959; Anderson, 1961; Heiser, 1973). Maize Cultivated maize (Zea mays L,) is the product of repeated racial hybridization within the species and recurrent intro gression from teosinte (Z. mexicana) and Tripsacum (Mangelsdorf, 1961). Anderson and Brown (1952) considered the hybrids between the Southern Dent and Northern Flint maizes diverse enough to be interspecific and suggested a reexamination of these races to create maximum heterozygosity.
