为了适应蚕业生产日益发展的需要,结合广东的实际情况,我们对桑树新品种选育的目标是:发芽早,生长期长,发条多,再生力强,叶片大而厚,抗性、适应性强,并具有高产稳产、品质优良的品种。桑树新品种“试11号”,正是围绕上述目标,通过有性杂交选育出来的。一、杂交组合和选育过程 1973年开始,从地方品种选拔出来比较优良的单株系中,选择“6301”、“北一”、“209”、“北七”、“109”、“伦540”和镇江蚕研所选育的优良品种“中桑5801”为材料,进行互相配对,确定杂交组合。1973年春总共配成杂交组合17个。1974年着重在成叶表现方面开始对各组杂交实生苗进行选拔。1976
In order to meet the needs of the growing development of sericulture, combined with the actual situation in Guangdong, we aim to select the new varieties of mulberry: early germination, long growth period, more spring, strong regeneration, large and thick leaves, resistance, Adaptable, and with high and stable yield, good quality varieties. Mulberry new variety “test No. 11”, it is around the above objectives, bred by sexual cross out. First, the hybrid combination and breeding process From 1973, selected from the local varieties of superior single lines selected, select “6301”, “North”, “209”, “North seven”, “109”, “Lun 540 ”and Zhenjiang silkworm Institute selection of elite varieties“ Zhong Sang 5801 ”as the material, for mutual pairing, to determine the hybrid combination. The spring of 1973, a total of 17 hybrid combinations. In 1974 the focus on the performance of leaves into the group of hybrid seedlings selection. 1976
