Cytogenetic evidence is presented that the cross between hexaploid bread wheat (Triticum aestivum, 2n = 42) and maize (Zea mays, 2n = 20) results in a hybrid zygote with one complete haploid chromosome set from each parent. Maize chromosomes are subsequently eliminated. This sytem has potential for wheat haploid production and may also allow segments of maize DNA, including transposable elements, to be transferred to wheat.Key words: wide crosses, wheat, maize, chromosome elimination, haploids.

Rectovaginal lacerations in the mare occur during parturition when the foal’s limb(s) or head are forced caudal and dorsal. The injury is seen predominantly in primiparous mares and is usually due to violent expulsive efforts by the mare (Colbern et al., 1985; Turner and McIlwraith, 1989). The injury is also seen following forced extraction of a large fetus or extraction before full dilation of the birth canal. Third-degree perineal lacerations occur when there is tearing through the rectovaginal septum, the musculature of the rectum and vagina, and the perineal body.

Penelitian ini bertujuan untuk mengetahui 1) jenis jamur patogen penyebab penyakit pada gulma daun sempit pada perkebunan tebu, 2) informasi virulensi jamur patogen terhadap gulma daun sempit pada perkebunan tebu, dan 3) informasi virulensi jamur patogen gulma daun sempit terhadap tanaman budidaya. Penelitian dilaksanakan di Laboratorium Perlindungan Tanaman dan rumah kaca, Fakultas Pertanian, Universitas Jenderal Soedirman, Purwokerto dilaksanakan dari Oktober 2019 sampai Agustus 2020. Penelitian ini terdiri atas tiga tahap yaitu eksplorasi, identifikasi, dan uji virulensi jamur patogen gulma. Eksplorasi dilakukan dengan pengambilan sampel gulma bergejala menggunakan metode purposive random sampling. Uji virulensi dilakukan pada gulma dan tanaman budidaya, yaitu Imperata cylindrica, Cyperus kyllingia, Cyeperus rotundus, Eleusine indica, Digitaria ciliaris, Oryza sativa, Zea mays, dan Sacharum officinarum. Variabel yang diamati adalah intensitas penyakit, masa inkubasi, area under diseases progress curve (AUDPC), bobot tanaman basah, dan bobot tanaman kering. Hasil dari eksplorasi diperoleh jamur patogen Curvularia lunata dan Fusarium oxysporum. Perlakuan jamur C. lunata pada gulma C. rotundus menunjukkan intensitas paling besar di antara gulma yang lain, dan perlakuan F. oxysporum dengan intensitas 22,5714% bahkan mampu menimbulkan kematian pada gulma C. rotundus. Sementara perlakuan jamur F. oxysporum menunjukkan intensitas yang lebih besar pada gulma D. ciliaris dengan kisaran 6,116%. Jamur patogen gulma daun sempit virulen terhadap gulma daun sempit dan tidak virulen terhadap tanaman budidaya yang diujikan.

<p>Insects’ oviposition behavior on alternate host plants is very helpful to understand the interaction between host plants and insects, the dynamics of insect populations, and the effectiveness of alternate host plants as refugia in managing insect resistance. The oviposition preference of <em>Ostrinia furnacalis</em> on maize (<em>Zea mays</em> L), king grass (<em>Panicum maximum</em> Jacq.), and cogon grass (<em>Imperata cylindrica</em> (L.) was studied through no-choice test, two-choice test, and three-choice test. The oviposition preferences hierarchy of <em>O. furnacalis</em> on maize, king grass, and cogon grass wass sequentially maize &gt; king grass &gt; cogon grass when the tested plants were at 21 DAP (days after planting). However, the hierarchy pattern may change depending on host plants phenology. The 35-day-old king grass was more preferred by <em>O. furnacalis</em> (proportion of eggs = 0.692; OPI = 37.57) than maize (proportion of eggs = 0.301; OPI = -38.780) and cogon grass (proportion of eggs = 0.174; OPI = -65.183) for oviposition. These findings indicated that king grass was a potential alternate host for <em>O. furnacalis </em>to survive and could serve as refugia in IRM strategy. However, it needs further research in the field to ensure the potential of king grass as refugia for <em>O. furnacalis.</em></p>
