The invention discloses a breeding method for wheat having fast
grain filling and fast
dehydration, and belongs to the field of wheat breeding. The method comprises the following steps: (1) carrying out parent research, identifying filling and
dehydration characteristics of wheat varieties, and determining a parent cross combination; (2) according to seed selection requirements, determining a
cross breeding or backcross breeding scheme; (3) in the seed selection process, comprehensively applying
morphological trait investigation, studies on
wheat grain filling and
dehydration characteristics, different-stage
sowing and yield identification, screening a
genotype having fast
grain filling, fast dehydration and high yield; and (4) breeding the new wheat variety having fast
grain filling and fast dehydration. According to the breeding method for the wheat having fast grain filling and fast dehydration, the
early generation morphological selection and the study on the grain filling characteristic and the dehydration characteristic are applied to wheat breeding at the same time, and the wheat material having fast grain filling and large dehydration rate can be accurately selected. The variety bred by the method has the advantages of
early maturation, good maturation performance and grain plumpness. The
filling rate is fast, the filling completing time is short and the thousand seed weight is high. The fast dehydration stage is immediately performed after high-efficiency completion of filling, the dehydration rate is fast, and the maturation period is short. Under the condition of late
sowing, the wheat can be still harvested in advance, and
crop rotation for rice can be performed in advance. The wheat adapts to new requirements of the current new wheat situation, and a foundation is laid for annual yield increase of rice and wheat in the middle and lower reaches of the Yangtze river.
