Doubled Haploid Breeding

Four Indian and one Japanese accession of Imperata cylindrica were assessed for their influence upon haploid production in F<sub>1</sub> generations of 21 wheat crosses (winter &times; spring, spring &times; spring and winter &times; winter) to find an efficient pollen source for haploid induction, which would enhance doubled haploid breeding in bread wheat. The frequency of haploid induction was influenced differently by the wheat and the I. cylindrica genotypes, indicating both maternal and paternal genetic influence on haploid induction. The gene actions controlling the inheritance of&nbsp; haploid induction&nbsp; appeared to be non-additive. Haploid formation efficiency was closely associated with other haploid induction parameters, i.e. pseudoseed formation, embryo formation and haploid regeneration. Amongst wheat F<sub>1</sub> groups, spring &times; spring wheats exhibited the highest potential for haploid induction. General combining ability for haploid production was highest for the, I. cylindrica genotype Ic-Aru, native to the northeastern Himalayas, which appears as a potential pollen source for efficient haploid induction in bread wheat.

Abstract An investigation to optimize the protocol for application of colchicine for enhancing the doubled haploid production in maize was done. 106 maize genotypes were used as maternal parents, whereas, pollen source involved tropically adopted haploid inducer (TAIL P1 and TAIL hybrid). After the elimination of chromosomes of inducer lines, haploid seeds were obtained from the crosses. Haploid seedlings were treated with three different doses, such as 0.04, 0.06 and 0.08 per cent of colchicines for different durations (8, 12 and 15 hours). The response of various colchicine concentrations applied for different time durations revealed significant differences at P ≤ 0.05 for various parameters viz., per cent plants survivability, stalk colour, the fertility of tassel, silk present/absent, pollen viability, seed set and per cent doubled haploid formation. In maize, colchicine doses of 0.04 per cent for 12 hours and 0.06 per cent for 8 hours, respectively were established as optimum for enhanced doubled haploid production. But among these two, 0.04 per cent for 12 hours was observed to be best dose for doubled haploid production in maize.
