Abstract

This investigation was carried out to compare PERFORMANCE of seven new SILKWORM LINEs including Japanese origin LINEs of Xinhang1, Xinhang2, Xinhang3, 101433 and Chinese origin ones including Koming1, Koming2, Y at three rearing periods using generalized LINEar model procedure. Survived larvae number, survived pupae number, pupation rate, and produced cocoon number were studied as economic characters. Also, good cocoon percentage, middle quality cocoon percentage, low quality cocoon percentage, and double cocoon percentage were studied as economic characters. Furthermore, total best cocoon weight, total cocoon weight by 10000 larvae, larval duration, total produced cocoon weight, single cocoon weight, single cocoon shell weight and cocoon shell percentage were studied as economic characters. Results from this study showed that Chinese LINEs have a higher genetic resistance than Japanese ones, thus Chinese varieties can be used as donor of resistance genes in crossbreeding programs. Total best cocoon weight for Chinese group was higher than Japanese ones in spring 1381 (P<0.05).Total cocoon weight by 10000 larvae was significantly different between Japanese group (12851 gr) and Chinese one (15355 gr) only in autumn rearing (P<0.05). Thus, for Chinese varieties have higher potent for unfavorite conditions. Generation had significant effect on total produced cocoon number, best cocoon percentage, and middle quality cocoon percentage. Also, generation had significant effect on low quality cocoon percentage, total best cocoon weight, and total cocoon weight by 10000 larvae (P<0.0001) and larval duration (P<0.001), while it had not significant effect on double cocoon percentage. At total rearing periods, Xinhang3 (34.16%) and Y (19.42%) had higher and lowest middle quality cocoon percentage. At autumn rearing, Xinhang2 (15.23%) and at spring rearing, 101433 (7.18%) had more low quality cocoon percentage.
