A recessive gene controlling male sterility sensitive to short daylength/low temperature in wheat (Triticum aestivum L.).

Utilization of a two-line breeding system via photoperiod-thermo sensitive male sterility has a great potential for hybrid production in wheat (Triticum aestivum L.). 337S is a novel wheat male sterile line sensitive to both short daylength/low temperature and long daylength/high temperature.

Bis{6,6'-dimeth-oxy-2,2'-[ethane-1,2-diyl-bis(imino-methyl-ene)]diphenolato(1.5-)-κO,N,N',O'}erbium(III).

In the title compound, [Er(C(18)H(22.5)N(2)O(4))(2)], the Er atom is located on a twofold rotation axis and is eight-coordinated by four O atoms and four N atoms from two symmetry-related 6,6'-dimethoxy-2,2'-(ethane-1,2-diyldiiminodimethylene)diphenolate(1.5-) ligands.
