The plants with normal fertility and characteristics of both parentssuch as the ear morphology of T.durum and clusterring bristles on glumeridges,hairiness of leaf edges and leaf sheath edges and the immunityto powdery mildew of H.villosa were obtained from self-pollinated oropen-pollinated progenies of(T.durum×H.villosa)_(F_1)hybrids.Cytologi-cal analysis showed that the 2n chromosome number of these plants eq-ualed to 42,20.5 bivalents and about lunivalent per PMC at MI ofmeiosis were observed.In nearly 80% of the PMC's there were 21 biva-lents.The results of observation of successive five generations in threeyears showed that the above-mentioned characteristics of these plantswere generally stable.By N-banding technique these plants have becnproved to be amphidiploids with AABBVV genome constitution com-prising AABB of T.durum and VV of H.villosa.The amphidiploid of T.durum and H.vill(?)sa is characterized by100-110 cm of plant height,9-12 cm of spike length,20-24 spikelets andabout 30 kernels per spike,25-35 grams of 1000 kernels and a highseed protein content of about 20%.It is immune to powdery mildew,re-sistant to leaf and stem rusts and susceptible to scab.When the amphi-diploid was crossed with bread wheat(T.aestivum,AABBDD)F_1 pla-nts showed some 14 bivalents and approximately 14 univalents per PMCat meiosis and 3% self-pollinating fertility.However,the fertilitycould be gradully increased generation by generation through back-cros-sing.Plants with immunity to powdery mildew were isolated from theback crossing population,and these plants might be used as a new bri-dge material for wheat improvement.The results from the investigation on(T.durum C.I.1320×H.vi-llosa)_(F_1)and on the amphidiploid indicated that(T.durum C.I.1320×H.villosa )_(F_1)may generate the gamets with non-reduced number of chro-mosomes,and a natural alloploid could be produced by fusion of thenon-reduced female and male gamets.This type or way of allopolyploidproduction may be of theoretical and practical importance.

乙烯利和三嗪二酮都是目前我国生产的较好的小麦杀雄剂,用乙烯利4000ppm+二酮4000ppm 混合液,从花粉母细胞形成-花粉双核期喷施,比单一药剂喷施药害较轻,有效喷药期长,不育率可达80~90%,雌芯受精能力亦不受影响。小麦与桥梁品种的杂种,经化学杀雄后在隔离区中与黑麦自然授粉,可获得大量的杂种。这不仅可节省人力和时间,而且还可利用化杀后保留的部份自交结实率,进行小麦与黑麦可杂交的新桥梁品系的选育。
