Description Induction of male sterility by deployment of male gametocides holds
immense potential in heterosis breeding of wheat. The efficacy of a new
class of male gametocide for wheat (Triticum aestivum L.) is described:
ethyloxanilates, the most active example of this class being ethyl
4-fluorooxanilate (E4FO). E4FO induces male sterility, specifically,
without detectable effects on various agronomic features and female
fertility. The plants sprayed once with 0.15% E4FO exhibited 100%
pollen and floret sterility without causing a significant reduction in
total yield. E4FO was screened on 29 genotypes of wheat at 0.15% test
concentration and was observed to induce 99.76 ± 0.37% male
sterility. Thirteen F1-hybrids of wheat were produced using the
gametocide in Winter 2000–2001 and were evaluated for their
agronomic performance in Winter 2001–2002. The cross combinations
viz., lines WR 544 · HW 2046 and HW 2044 · WR 956 have
outperformed their respective better parents by 48.17% and 23.42%
in grain yield/plant and thus have potential as hybrids.
