摘要
1996年春期在临安蚕种总场进行春用蚕品种比较试验。供试蚕品种是菁松、皓月、浙蕾、春晓,春·蕾、镇·珠及其正反一代杂种。对比结果:春用一代杂种均属体强丰产多丝量品种类型。进一步分析,各杂交组合各有所长。菁松×皓月最大特点是丝质特别优良,解舒率高达77.45%,然产虽量及其杂种优势率较低;浙蕾×春晓产茧量居中,然杂种优势率较高,丝质也优良,解舒率73.85%;春·蕾×镇·珠产茧量最高,杂种优势率较高,然丝质较差解舒率仅64.41%。
The comparison experiment was carried out in Linan General Egg Station inspring 1996. Silkworm varieties reared were Jingsong, Haoyue,Zhelei,Chunxiao,Chun·Lei,Zhen·Zhu and its first reciprocal hybrids. The result revealed that the hybrids for springrearing were all healthy,high yield,more silk. Further analysis indicated that each cross com-bination has its own strong points. The biggest merit is that silk quality is specially fine,reelability reach 77. 45% high, but the cocoon yield and heterosis is low; cocoon yield ofZhelei × Chunxiao is secondary,while its heterotic vigor is high,silk quallty is fine too,its un-winding ratio 1s 73. 85%;the cocoon yield of Chun·Lei ×Zhen·Zhu is the highest,hybridvigor is higher,yet,and silk quality is inferior,its reelability is merely 64. 41 %.
