摘要
为选育出对人工饲料适应性优良的家蚕品种,对15个家蚕资源种(中系品种5个,日系品种10个)进行人工饲料育适应性筛选试验,调查各品种饲育区收蚁48h的疏毛率、96h和192h的起蚕率及全茧量、茧层量、茧层率、死笼率和虫蛹率等主要经济性状。结果表明:15个家蚕品种饲料育中,疏毛率较高的品种是RCA、872A和D-2,在78.70%~89.97%;96h起蚕率较高的品种是RCA、D-2和秋白,为65.2%~88.65%,192h起蚕率较高的是RCA、秋白和D-2,为60.88%~88.21%;综合评分排前5位的品种依次为RCA、D-2、秋白、皓月和872A;无论中系还是日系,不同品种的桑叶育(CK)与饲料育间的发育经过差异不大;饲料育全茧量较高的品种是871B、873和限2,茧层量较高的品种是871B、限2和873,死笼率以734、H72和873较低,分别为0.52%,0.38%和0;虫蛹率以限2、826和7532较低。中系种RCA、202黄,日系种D-2、秋白、734、H72和限2的人工饲料育适应性较好。
To select Bombyx mori varieties with good adaptability for artificial feed,a adaptability screen test of 15 B.mori varieties(five Chinese varieties and 10 Japanese varieties)fed with artificial feed was conducted to investigate the main economic characters of 48 hsetae dispersion rate of the larvae,96 h and 192 hnewly molted larva rate,whole cocoon weight,cocoon shell weight,cocoon shell percentage,dead cocoon rate and pupation rate of B.mori.Results:The 48 hsetae dispersion rate of RCA,872 Aand D-2 in the 15 B.mori varieties was 78.70%-89.97%.The 96 hnewly molted larva rate of RCA,D-2 and Akubai was 65.2%-88.65%,and the 192 hnewly molted larva rate of RCA,Akubai and D-2 was60.88%-88.21%.RCA,D-2,Akubai,Haoyue and 872 A ranked the top five according to the comprehensive score.There was no obvious difference in development process of different varieties(whether Chinese varieties or Japanese varieties)fed with Folium mori(CK)and feed.The whole cocoon weight of 871 B,873 and Limit 2 fed with feed was higher.The cocoon shell weight of 871 B,Limit 2 and873 fed with feed was higher.The dead cocoon rate of 734,H72 and 873 fed with feed was 0.52%,0.38%and 0.The pupation rate of Limit 2,826 and 7532 fed with feed was lower.The adaptability of Chinese varieties of RCA,202 Yellow and Japanese varieties of D-2,Akubai,734,H72 and Limit 2 fed with artificial feed was better.
