一、從名稱上區別從專業術語角度講，雜交種子名稱(cheng)叫組合，常(chang)規種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)的(de)(de)(de)名稱(cheng)叫品(pin)種(zhong)(zhong)(zhong)(zhong)。從農業生產(chan)角度(du)講，雜(za)交種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)和(he)常(chang)規種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)的(de)(de)(de)名稱(cheng)可統稱(cheng)為品(pin)種(zhong)(zhong)(zhong)(zhong)，“品(pin)種(zhong)(zhong)(zhong)(zhong)”是(shi)(shi)廣義的(de)(de)(de)稱(cheng)呼。在種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)的(de)(de)(de)包裝物表(biao)面和(he)標(biao)簽上(shang)的(de)(de)(de)種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)類(lei)別欄和(he)品(pin)種(zhong)(zhong)(zhong)(zhong)欄應標(biao)明是(shi)(shi)雜(za)交種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)或(huo)常(chang)規種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)，標(biao)注“組合”的(de)(de)(de)是(shi)(shi)指(zhi)雜(za)交種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)，標(biao)注“品(pin)種(zhong)(zhong)(zhong)(zhong)”的(de)(de)(de)則指(zhi)常(chang)規種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)或(huo)雜(za)交種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)。

      二(er)、從種(zhong)子的特征特性區(qu)別雜(za)交(jiao)種(zhong)子不如常(chang)規(gui)種(zhong)子飽(bao)滿，秕粒(li)、裂粒(li)(殼(ke))粒(li)較(jiao)多。雜(za)交(jiao)種(zhong)子吸水速(su)度、發(fa)芽(ya)速(su)度較(jiao)常(chang)規(gui)種(zhong)子快(kuai)，但發(fa)芽(ya)率較(jiao)常(chang)規(gui)種(zhong)子低(di)。雜(za)交(jiao)種(zhong)子種(zhong)植(zhi)后(hou)結(jie)實的種(zhong)子，如果再(zai)作種(zhong)用，后(hou)代表現(xian)性狀(zhuang)分離，常(chang)規(gui)種(zhong)子可多代利用，后(hou)代不表現(xian)分離。

      三、從種子包裝物和標簽標注的內容識別根據農業部有關規定，有性繁殖作物的種子應當包裝后銷售，無性繁殖作物的器官和組織(根、莖、葉、芽、細胞等)及苗子，可以不包裝銷售。包裝的種子或不包裝的種子，都應當有規范的標簽和標注內容。標注的內容為作物種類、種子類別、品種名稱、產地、種子經營許可證編號、質量指標、檢疫證明編號、凈含量、生產年月、生產商名稱、生產商地址及聯系方式。主要農作物(稻、麥、玉米、棉花、大豆、油菜、馬鈴薯)種子還應加注品種審定號、種子生產許可證編號。種子標簽名冊標注內容可直接負責制在包裝物表面，也可制成印刷品固定案在包裝物上或放在包裝物內，但作物種類、品種名稱、生產商、質量指標、凈含量、生產年月、警示標志、“轉基因”標(biao)志等內(nei)容必須印制在包裝物外表(biao)。標(biao)簽標(biao)注內(nei)容應(ying)當(dang)使(shi)用(yong)(yong)(yong)規范的(de)(de)(de)中(zhong)文，印刷清晰，字(zi)體高度不得小(xiao)(xiao)于(yu)1.8毫升，警示(shi)標(biao)志應(ying)當(dang)醒目，可以同時使(shi)用(yong)(yong)(yong)漢語拼音和其他文字(zi)，字(zi)體應(ying)小(xiao)(xiao)于(yu)相(xiang)應(ying)中(zhong)文。可以不經過(guo)中(zhong)工包裝進行銷售(shou)的(de)(de)(de)種(zhong)(zhong)子(zi)(zi)，標(biao)簽應(ying)當(dang)制成(cheng)印刷品，在銷售(shou)種(zhong)(zhong)子(zi)(zi)時提供種(zhong)(zhong)子(zi)(zi)使(shi)用(yong)(yong)(yong)者。印刷品標(biao)簽的(de)(de)(de)制作材料應(ying)當(dang)有足夠的(de)(de)(de)強度，長×寬不小(xiao)(xiao)于(yu)12厘(li)米(mi)×8厘(li)米(mi)。根(gen)據種(zhong)(zhong)子(zi)(zi)類別，使(shi)用(yong)(yong)(yong)不同顏色(se)(se)的(de)(de)(de)標(biao)簽，育種(zhong)(zhong)家種(zhong)(zhong)子(zi)(zi)使(shi)白色(se)(se)并有紫色(se)(se)單(dan)對角條紋，原種(zhong)(zhong)使(shi)用(yong)(yong)(yong)藍色(se)(se)，親本(ben)種(zhong)(zhong)子(zi)(zi)使(shi)用(yong)(yong)(yong)紅色(se)(se)，大田(tian)用(yong)(yong)(yong)種(zhong)(zhong)使(shi)用(yong)(yong)(yong)白色(se)(se)或藍紅以外的(de)(de)(de)單(dan)一(yi)顏色(se)(se)。 (何崇陽)
