【摘要】 2003～2004年在印度南部的50家农户进行了4次二化性家蚕品种农村试养,结果表明:供试品种生长发育经过较印度二化性家蚕品种慢,茧丝质优于印度对照种,适应性、抗逆性整体表现较印度对照种弱。由于气候、饲养技术、叶质等的差异,与其在国内的饲养相比,印度饲养试验中供试品种的各项性能指标均偏低,生产能力达不到国内水平。印度南部适宜饲养二化性家蚕的季节为9月至翌年的3月,进入4月后,不宜饲养二化性家蚕品种。更多还原

【Abstract】 Four field trials for rearing bivoltine silkworm F₁ hybrids had been done in South India during 2003 to 2004.A total 50 farmers in 30 villages were selected to rear these hybrids.The results showed that the growth of test races was slower than that of Indian races’ under Indian rearing conditions.The quality levels of cocoons and silk of the test races were better than that of Indian controls’,but the adaptability and resistibility of the test races were a bit less than that of Indian controls.Moreover,due to the difference in climate,rearing technique,and in leaf quality and so on,the rearing results of the test races in India were inferior to that in China.The suitable seasons for rearing bivoltine silkworm races are from September that year to March next year in South India,When it comes to April,bivoltine silkworm races are unsuitable to be reared.更多还原
