Accessions hybrid BC1 F2 were backcrossed, with two elite parents Diantun502 and Flcxi35 widely cultivated in Yunnan as recurrent parent, while 548 accessions core collection in Yunnan rice landrace as donors. Under natural low temperature 18.1℃ at booting stage, the genetic variation to main morphological characters of core collection hybrids in Yunnan rice landrace was analyzed between indica and japonica, rice cropping regions.

在昆明孕穗期平均温度181℃的自然低温下，以云南当家品种滇屯502和合系35作轮回亲本，以548份云南稻核心种质为供体亲本配制的杂种BC1F2（458份）为材料，按籼粳、稻作区进行云南稻核心种质杂种后代形态性状遗传变异研究。

The results showed that the best ratio of male parent to female parent was 1:3, and 210 kg/hm2 N fertilization was better. It indicated that hybrid seeds production in two crop seasons, especially the second crop season based on the utilization of ratoons of flue-cured tobacco which regenerated after hybrid seed was harvested in the first crop season, was beneficial to higher seed yield, lower cost, and less laborers employed as well.

结果表明，烟草杂交制种父母本比例以1：3较好；在中等肥力田块制种头季以施纯氮195~210kg/hm2较理想；利用头季杂交种收获后萌生的腋芽进行杂种二季制种在提高杂种种子产量，降低劳动量和生产成本等方面具有较理想的效果。

Compared with Zhongza29, yields of super okra leaf and okra leaf hybrids were obviously lower, but semi-Okra leaf hybrids was 1.16% higher in yield of seed cotton and 2.06% in yield of lint cotton, and 10 days earlier in maturation. Semi-Okra leaf cotton hybrid, CLA 17 ZR4, which was made by super Okra leaf sterile line and Zheda strong restorer line, had a 13 % higher yield over CK.

测定发现，超鸡脚叶、鸡脚叶、中鸡脚叶、大鸡脚叶和正常叶5类杂种的生育期依次随叶面积系数增加而延长，中鸡脚叶杂种因具有适中的生育期和叶面积系数，产量和光合作用性状的综合表现最好。

The results were as follows:The protein,wet gluten content and sedimentation of all hybrid seeds with 4 alien cytoplasms were superior to those with T.aestivum cytoplasm.The differences of wet gluten content and sedimentation of hybrid seeds with Ae.kotschyi and Ae.variabilis cytoplasms,at 5 percent significant difference,were especially obvious.

结果表明，由它们所配制的杂种小麦在蛋白质含量、湿面筋含量、沉淀值等性状上均高于具有普通小麦细胞质的相同核型杂种小麦，尤其粘、易型某些组合在湿面筋含量、沉淀值两性状上差异达到显著水平。
