As expected, the [F.sub.1] hybrids were generally more productive compared to the inbred lines
The inbred lines
and hybrids of maize in present investigation were evaluated under artificial epiphytotic conditions during kharif 2014 and kharif 2015 to identify resistance source and to develop resistant maize hybrids against turcicum leaf blight (Helminthosporium turcicum).
VENCOVSKY & BARRIGA (1992) emphasized that the base populations selected for the extraction of inbred lines
should exhibit a high frequency of favorable alleles and a low frequency, or low expression, of negative alleles.
Inducer line, Stock-6 x CMST x Ig-gene showed highest induction rate among the four studied inducer lines and this inducer line could be used comparably with TAILs for further homozygous and homogeneous inbred line

populations of indicarice," Journal of Integrative Agriculture, vol.
In the conversion of normal inbred lines
to QPM the inbred line
CML144 was used as donor; for the conversion of VS-536, the V-537C variety was used.
In the case of inbred lines
and landraces, the total number of polymorphic alleles was 172 and 168, respectively.
The inbred lines
were grown in three-row plots with 10 m length and 75 cm spacing between rows.
Since 1995, PSR has used its Rapid Inbreeding technology to develop inbred lines
from unencumbered public materials.
A second experimental OPV was formed for each of the four cases (i.e., Across, Tanzania, Ethiopia, and Uganda) by recombining the most advanced inbred lines
for each selected full-sib family For each of the full-sib families selected to form the four full-sib-based OPVs described above, remnant seed of the most advanced surviving inbred generation ([S.sub.1] to [S.sub.3]; Table 2) from selections in MSV nurseries at Harare was used to represent the selected full-sib family for recombination to form an inbred-based experimental OPV (i.e., 'AC969A([S.sub.n])-SR', 'TZ969A([S.sub.n])-SR', etc.; Table 1).
Some argue heirloom plants and vegetables are those introduced before 1951, when hybrids were developed from inbred lines
. However, not everyone agrees with this definition.
