现今的小麦品种均为单子房小麦.一个麦壳中只生长一粒麦子,而多子房小麦一个麦壳中可生长多粒麦子。1990年春天,银川市科委小麦育种组农艺师郭善昌从一株麦穗上发现3个麦壳中有9粒多子房小麦.他将其单独播种,全部长出多子房小麦.然后用多子房小麦与普通单子房小麦杂交.所生交杂一代中.多子房和单子房小麦各占一半.杂交二代中多子房小麦占到2/3。均为每壳生长
Today’s wheat varieties are all monocotyledonous wheat, with only one grain of wheat growing in one wheat husk and more grain of wheat in one hulled wheat husk. In the spring of 1990, Guo Shanchang, an agronomist in the wheat breeding group of the Yinchuan Municipal Science and Technology Commission, discovered from the wheat ears 9 grain moults of 9 multi-ovary wheat, which he sowed individually and all grew in multi-ovary wheat. Hybridization of multi-ovary and common monocotyledonous wheat resulted in half-oviparous and monocotyledonous hybrids, with hybrid progeny accounting for two-thirds of all hybrids. Each shell growth
