【摘要】 本文以穗重型、穗数型、大粒型、多小穗型、远缘型、不同生态型、中间型的父本与重庆温光型核不育小麦Ｃ４９Ｓ测配，对所配１２８个组合的杂种Ｆ１的产量性状进行初步分析。其优势主要表现在干粒重、穗长的提高，另外，株穗数、穗粒数有较强的杂种优势。Ｃ４９Ｓ对降低Ｆ１株高有明显的竞争优势，各类型都有筛选出Ｃ４９Ｓ强优势组合的可能。更多还原

【Abstract】 A primary study has been made on 128 hybrids wheats coming from thecombination of Chongqing Thermo-Photoperid Sensitive genic male steril ity Wheat <C49S> and many typical Wheats including weighty-eared type、numberous-eared type、 big-grained type、 numberous-earlited type. distant-related type、different-ecological type and so’ on. The result indicatesthat the superiority of hybrids is attributed mainly to the weight of onethousand grains and the length of eat in addition to the number of eachplant’s tillers and the number of each ear’s Yaluable grains. it also hasbeen proved that C49S can evidently decrease the height of hybrids and the superior hybries that can be used may be selected from all the tvpes更多还原
