        <dc:description>Flowering time is an important trait of chickpea that influences&#13;
crop adaptation to a given climate. Earliness in both flowering&#13;
time and maturity are important traits for increasing and&#13;
stabilizing chickpea productivity in short season environments&#13;
by avoiding end of season drought. A study was conducted to&#13;
identify genes/quantitative trait loci (QTLs) controlling flowering&#13;
time in chickpea using four F2 populations (ICCV 96029 × CDC&#13;
Frontier, ICC 5810 × CDC Frontier, BGD 132 × CDC Frontier and&#13;
ICC 16641 × CDC Frontier). Genetic studies revealed monogenic&#13;
control of flowering time in the crosses ICCV 96029 × CDC&#13;
Frontier, BGD 132 × CDC Frontier and ICC 16641 × CDC Frontier,&#13;
while in the cross ICC 5810 × CDC Frontier, it was under digenic&#13;
control with complementary gene action. The genetic linkage&#13;
maps developed from four crosses consisted of 75, 75, 68 and 67&#13;
markers spanning 248.8 cM, 331.4 cM, 311.1 cM, and 385.1 cM,&#13;
respectively. A consensus map spanning 363.8 cM with 109 loci&#13;
was developed by integrating four genetic maps. QTL mapping&#13;
detected major genomic regions controlling early flowering genes&#13;
efl-1 (Qefl1-2) on CaLG04, efl-2 (Qefl2-1, Qefl2-2, Qefl2-3, Qefl2-&#13;
4) on CaLG01, 03, 04 and 08, efl-3 (Qefl3-3) on CaLG08 and efl4&#13;
(Qefl4-1) on CaLG06. Analysis of QTL regions on CaLG04 and&#13;
CaLG08 provided several important candidate genes involved in&#13;
regulation of flowering time and homeotic functions. The identified&#13;
genomic regions with linked molecular markers can be deployed&#13;
for introgressing early flowering trait into elite chickpea&#13;
cultivars through marker-assisted breeding (MAB).</dc:description>
