All the significant and positive SCA effects for PY and GY were recorded in the crosses among Sosat C 88 with the inbred lines
IBL 179-2-1, IBL 091-1-1, and IBL 021-3-1.
Out of thirty inbred lines
, ten lines viz., DMIT 105, DMIT 106, DMIT 111, DMIT 113, DMIT 118, DMIT 121, DMIT 123, DMIT 124, DMIT 125 and DMIT 126 recorded less than or equal to score 2 and grouped them as resistant; twelve inbred lines
viz., DMIT 101, DMIT 103, DMIT 104, DMIT 107, DMIT 108, DMIT 109, DMIT 110, DMIT 112, DMIT 119, DMIT 122, DMIT 127 and DMIT 129 possessing score 3.0 were categorized as moderate resistant and eight inbred lines
viz., DMIT 102, DMIT 114, DMIT 117, DMIT 120, DMIT 130, DMIT 115, DMIT 116 and DMIT 128 exhibited TLB score 4 were categorized as susceptible and susceptible check (CM202) had score 5 was categorized as highly susceptible to TLB (Table 2).
Higher means from the expected inbred lines
expected for YU and YC were observed with genotypes AG4051 and AM811, and for GM, the AM811 and Cativerde 02 genotypes were superior.
NP, number of panicles per plant; NGP, number of grains per panicle; NSP, number of spikelets per panicle; SF, spikelet fertility; TGW, 1000-grain weight; GY, grain yield per plant; RIL, recombinant inbred line
; TC, testcross [F.sub.1]; [H.sub.MP], mid-parent heterosis.
Also, these inbred lines
showed good agronomical characteristics; such as good appearance and health on plant and ear, tolerant to lodging, with good husk cover, dent and semi-dent texture; in addition to the advantages that the high quality protein maize represents for consumers (Ortega et al, 1986; Bressani, 1994; Larkins et al., 1994; Mertz, 1994; Vasal, 2002; Chavez and Munoz, 2004; Espinosa et al., 2005, 2006).
Among the tested primers, E-ACT x M-CTG, E-ACT x M-CTT, E-AAC x M-CAA, E-AAC x M-CAC, E-AAC x M-CAG and E-AAC x M-CAT were important combinations for either germplasm screening, landrace accessions, inbred lines
and other studies like genetic mapping and molecular assisted selection.
Results of ANOVA showed significant differences among different levels of drought stress, inbred lines
and interaction between drought stress and inbred lines
had for grain yield, grain starch percent and grain protein percent under studied conditions (Table 2), which demonstrated existence of high diversity among inbred lines
studied for drought tolerance and different between time of applied stress.
The Syn1 generation for each experimental OPV was formed at Harare in summer 1997-1998, using 34 plants for each FS, or 17-34 plants for each of one to four inbred lines
derived from each of the 14 selected FS (Table 2), dividing the families into two groups, and making half-sib pollinations among the two groups on at least three dates.
Some authorities say heirloom vegetables are those introduced before 1951, when modern plant breeders introduced the first hybrids developed from inbred lines
. While there are good reasons to use 1951 as a cut-off, many heirloom gardeners focus on varieties that date from the 1920s and earlier.
For example, whereas selected lines bred for high and low alcohol consumption should differ in the amount of alcohol ingested but not in an unrelated trait (e.g., coat color), inbred lines
may differ in both alcohol consumption and the unrelated trait.
alba were sampled, and five generations of sib mating resulted in 65 inbred lines
, with inbreeding coefficients of f = 0, 0.25, 0.375, 0.5, and 0.59 per line.
