以普通小麦（Ｔｒｉｔｉｃｕｍａｅｓｔｉｖｕｍ２ｎ＝６ｘ＝４２）为母本和奥地利黑麦（Ｓｅｃａｌｅｃｅｒｅａｌｅ，２ｎ＝２ｘ＝１４）杂交，对其杂交亲和性和杂种Ｆ１的染色体配对行为进行了观察，结果表明，供试２２个品种的杂交亲和性存在明显差异，４个品种的杂交结实率大于５０％，其可能基因型为ｋｒ１ｋｒ１ｋｒ２ｋｒ２，４个品种的杂交结实率介于３０％～５０％之间，其基因型可能为ｋｒ１ｋｒ１Ｋｒ２Ｋｒ２，４个品种的杂交结实率介于１０％～３０％之间Ｋｒ１Ｋｒ１ｋｒ２ｋｒ２，７个品种杂交结实率小于５％；基因型可能为Ｋｒ１Ｋｒ１Ｋｒ２Ｋｒ２；杂种Ｆ１ＰＭＣ的染色体配对能力与亲本杂交亲和性无明显相关，相关系数为０．０１２１，但不同组合存在一定差异，８６４１０１２／黑麦Ｆ１具有最好的配对能力（平均交叉结数＝１．３），而碧蚂４号／黑麦等具有较差的配对能力（平均交叉结数为０），其它品种（系）介于二者之间。８６４１０１２是具有较好亲和性和较高Ｆ１ＰＭＣ染色体配对水平的综合性状优良的小麦品系，可进一步用于小麦的远缘杂交以转移外源遗传物质。
The crossbreeding compatibility of hybrid wheat F1 and the mating behavior of hybrid F1 were observed using the cross between Triticum aestivum2n = 6x = 42 and Secalecereale (2n = 2x = 14) as the female parent. The results showed that the test The hybridization compatibility of 22 cultivars was significantly different. The hybrid seed set rate of 4 cultivars was more than 50%. The probable genotypes were kr1kr1kr2kr2. The hybrid seed set rate of 4 cultivars ranged from 30% to 50% Which may be kr1kr1Kr2Kr2. The seed setting rate of 4 hybrids between 10% and 30% is Kr1Kr1kr2kr2, the seed setting rate of 7 hybrids is less than 5%, and the genotype may be Kr1Kr1Kr2Kr2. The hybridization ability of hybrid F1PMC with the parental hybridization affinity No significant correlation, the correlation coefficient of 0.0121, but there are some differences between different combinations, 8641012 / rye F1 has the best Capacity (number average crossing junction = 1.3), while Bima 4 / rye, etc. have a poor ability to match (crosspoint node number average 0), other species (lines) interposed therebetween. 8641012 is a wheat line with good characters of good affinity and higher F1PMC chromosome pairing level and can be further used for the distant hybridization of wheat to transfer exogenous genetic material.
