Four selection method treatments for progenies of two crosses were used in Gongzhuling, Jilin,and Hainan island,Guang Dong, to determine optimum selection method and corresponding cross type under normal growth season condition in Jilin or abnormal growth season condition in Hainan island.Two crosses were made in 1980. Cross Jiunong 13×Tiejiao 7555 had larger difference in growth period between the parents. Two parents in cross Gongjiao 7622×Gongjiao 7513-1 had similar growing period. Seeds from each of...

Four selection method treatments for progenies of two crosses were used in Gongzhuling, Jilin,and Hainan island,Guang Dong, to determine optimum selection method and corresponding cross type under normal growth season condition in Jilin or abnormal growth season condition in Hainan island.Two crosses were made in 1980. Cross Jiunong 13×Tiejiao 7555 had larger difference in growth period between the parents. Two parents in cross Gongjiao 7622×Gongjiao 7513-1 had similar growing period. Seeds from each of 15 F2 plants in a cross were divided into two equal parts. F3 genertion were grown respectively in Gongzhuling, Jilin, and Hainan island, Guangdong and subjected separetely to following selection methods: (1) selecting superior plants in a cross, (2) selecting superior plants in 5 superior lines in a cross ,(3)random taking plant in a cross and (4) mass selection (Pod detaching method). In 1984 and 1985, twenty four F4 or F5 lines from each of 4 treatments in two locations were evaevaluated in Gongzhuling. The experimental results indicated that all treatments except mass selection on cross with larger parental maturity difference, had significant growing period difference among F4 lines. The lines selected in Hainan island had larger maturity period in range. The difference among the treatments was less for less parental difference cross. Materials obtained in Gongzhuling was early than that obtained by same method in Hainan island, but middle-late-maturing type prevailing was similar in the progeny materials. For cross Jiunong 13×Tiejiao 7555, random selection in Hainan island gave most high-yielding lines in F4 and F5 lines, highest mean line yield and highest-yielding line, following mass selection in Hainan island. For cross Gongjiao 7622×Gongjiao 7513-1, treatment of selecting plants in superior lines had best selection effectiveness. Low-yielding lines from mass selection or random selection were more than that from other selection methods. These results suggested that we should used different selection methods for different crosses, and gross-line random selection method should be used for less parental difference cross in Hainan island.

本研究拟通过不同类型组合在南北两地分别采用四种选择方法的比较,找到适于北方正常条件下或南繁加代的选择方法及相应的组合类型。以1980年配制的两亲本生育期差异明显与不明显的两个组合后代为材料。15个F_2单株的种子被分成二部份,一部份在海南岛种植F_3代,一部份在公主岭种植F_3代,在南北两地对F_3代均进行如下处理:1)组合内选优株,2)优良系统内选优株,3)组合内随机取株,4)混合摘荚。1984与1985年于吉林公主岭分别种植两地各处理的F_4、F_5品系,每个处理各24个品系。试验结果表明,两亲差异大的组合,除混合选择处理外,其它处理的生育期均出现差异,即在海南岛选择的生育期变幅较大。两亲差异小的组合,处理间差异小。相同选择方法不同地点选择的亦表现出南方选择偏早类型较多,但占优势的中晚熟类型差异不大。两亲差异大的组合,以在海南岛随机选择处理的F_4、F_5代高产品系较多,各品系平均产量及最高产品系的产量也高;其次为在海南岛进行混合选择处理者。亲本差异小的组合则相反,以公主岭优系选择处理的效果为最好。两类组合的在海南岛进行混合或随机选择处理的低产品系也较多。这些结果说明:不同类型的组合应采取不同的选择方法。...

In this paper, a early-mature type'and a late-mature type of gametophytes in some Laminariales have been reported. The character of early-mature type and late-mature type can keep on a longer time. In the case of culturing free gametophytes for reservation in the room, the mature rate of free gametophytes was less due to the reproduction of the late-mature type of gametophytes. And the longer the time of cultivation, the lower...

In this paper, a early-mature type'and a late-mature type of gametophytes in some Laminariales have been reported. The character of early-mature type and late-mature type can keep on a longer time. In the case of culturing free gametophytes for reservation in the room, the mature rate of free gametophytes was less due to the reproduction of the late-mature type of gametophytes. And the longer the time of cultivation, the lower the mature rate will be.By the method of picking out the early-mature type it in a definite time and culturing them in a suitable condition will keep the maturity of free gametophytes for a longer time.

The "Normal Type" and"Late-maturing Type" in the bone development of the men players occupied 58.2% and 7% respectively and the women players occupied 77.6% and 8.2% respectively. In the "Early-maturing Type", the men players occupied 34.9% and women players...
