抗病鉴定表明,纤毛鹅观草(Roegneria ciliaris,2n=28,SSYY)对麦类赤霉病具有较高的抗病性。用离体/活体胚培养法成功地获得了纤毛鹅观草与普通小麦(Triticumaestivum,2n=42.AABBDD)属间杂种。杂交结实率为67.74%,胚培成苗率为5.41%。F_1杂种生活力强、雄性不育,形态特征介于双亲之间并偏向小麦亲本。F_1杂种染色体数为预期的2n=35(SYABD),花粉母细胞减数分裂中期Ⅰ染色体构型平均为32.86个单价体、0.93个棒状二价体、0.13个环状二价体和0.006个三价体。对杂种的形态学、染色体行为、雄性不育机制以及潜在的育种价值进行了讨论。 Resistance evaluation showed that Roegneria ciliaris (2n = 28, SSYY) had high resistance to Fusarium graminearum. In vitro / in vivo embryo culture successfully obtained the ciliopsis and common wheat (Triticum aestivum, 2n = 42.AABBDD) interspecific hybrids. Seed setting rate was 67.74%, embryo culture seedling rate was 5.41%. F1 hybrids have strong viability, male sterility, morphological traits between parents and the preference of wheat parents. The chromosome number of F1 hybrids was expected to be 2n = 35 (SYABD), and the metaphase I chromosomes of pollen mother cells averaged 32.86 monovalent, 0.93 rod-shaped bivalents, 0.13 ring-shaped bivalents and 0.006 tris Price. The hybrid morphology, chromosomal behavior, male sterility mechanism and potential breeding value were discussed.
