Description To enhance the adaptability of pigeonpea at higher
latitude and altitude, a breeding program was initiated at
ICRISAT involving different sources of early-maturity.
A full diallel mating design involving 11 early-maturing
lines were used as parents. In F2–F5 generations, selection
was followed for early flowering and maturity, grain
yield and 100-seed weight by pedigree method. Four
brown seeded (ICPX 060064-4-6-10, ICPX 060077-6-5-14,
ICPX 060064-4-6-2 and ICPX 060063-11-8-4) and one
cream seeded (ICPX 060036-13-4-8) F4/F5 indeterminate
super-early progenies that matured, respectively 25 and
23 days earlier than the control cultivar ICPL 88039 were
recovered. ICPX 060036-13-4-8 recorded 107% and
34% grain yield advantage over the checks ICPL 86022
and ICPL 88039, respectively. These super-early lines
were derived from crosses involving AL 1518-2 × ICPL
85010, AL 1621 × MN 5, AL 1518-2 × MN 8 and MN 8
× AL 1518-2. Other super-early progenies [ICPX
060016-10-8-1 (from MN 1 × AL 1518-2 cross) and
ICPX 060017-12-12-20 (from MN 1 × AL 1621 cross)]
with greater 100-seed weight were also recovered.
Besides serving as excellent donors for earliness, these
lines may be photo/thermo insensitive. These super-early
pigeonpea lines may open new niches for this crop and
help in intensification of farming system.
