In this research an influence of the strong source restriction meaning cutting off the whole
plants at the first internodes 5 (5DAPt), 10 (10DAPt) and 15 (15DAPt) days after pollination
on grain yield and its corresponding traits in maize were tested. Control represented plants
harvested at full maturity. Four inbred lines were used, two historical ones (Mo17 and B73)
and two commercial ZP inbreds (ZPL and ZPB). The experiment was conducted at Zemun
Polje, Serbia, in 2014 and 2015. The trait of particular importance was the number of kernels
per ear and its average values were 37.73 at 5DAPt, 115.14 at 10DAPt and 175.20 at 15DAPt,
being sufficient for planting next generation of breeding. According to the results obtained,
ZPL represented an improved Lancaster line over Mo17 regarding drought tolerance, that
could not be stated for ZPB over B73. Hybrid among these two lines is drought tolerant due to
heterosis (epistatic effects) or dominant origin of ZPLs good response to dr...ought stress.
Values for seed set and eventually for grain yield per plant were 0.00 for line B73 at 5DAPt in
2015. An improved breeding scheme for increased drought tolerance could be proposed,
namely self-pollination of border plants on high density sown selfing progenies or dihaploid
(DH) lines, cutting off selfed plants at 15 DAP and evaluating their kernel properties. Openpollinated progeny would serve to estimate other important traits for selection. From the
chosen progenies kernels of selfed and cut-off plants should be used for the next generation of
breeding.
