2、數(shù)可以用來鑒定小白菜對黃曲條跳甲成蟲的抗蟲性。為了創(chuàng)新小白菜對黃曲條跳甲的抗蟲性種質(zhì)資源，采用“葉片受害孔洞計(jì)數(shù)法”篩選了100個品種小白菜對黃曲條跳甲成蟲的抗蟲性，得到了5個相對抗蟲品種(‘新矮青9’、‘新夏春3號’、‘918’、‘泰國種子一2’、‘夏冠’)和5個相對感蟲品種(‘楚青325．6’、‘青優(yōu)’、‘雞毛菜’、‘12#耐抽苔青梗x668—1’、‘富士’)，5個相對抗蟲品種孔洞數(shù)間均無差異，但均極顯著低于5個相對感蟲品種，這些材料為小白菜抗蟲育種奠定了基礎(chǔ)。關(guān)鍵詞：小白菜；黃曲條跳甲；抗蟲性中圖分類號：$332．3文獻(xiàn)標(biāo)志碼：A論文編號：20
