4) cross seed set
[农]杂交结实
5) self-fruitful rate
自交结实率
1.
The association of self-fruitful rate and rate of pollen stained with 1%I2-KI of F2 of A2 cytoplasmic male sterility(CMS)and A3 CMS in Sorghum was analyzed with F2 populations of three A2CMS cross classifications(A2T×622×Jinliang 5,A2V4×1383-2 and A2V4×Jinliang 5) and three A3CMS cross classifications(A3 299×1174、A3 2457×1174、A3JW×1174).
以高粱3个A2类型杂交种(A2TX622×晋粱5号、A2V4×1383-2、A2V4×晋粱5号)和3个A3类型杂交种(A3299×1174、A32457×1174、A3JW×1174)的F2群体为材料,来进行A2?A3类型高粱F2代花粉碘染色率与田间自交结实率之间关系的研究。
6) Outcrossing rate
异交结实率
1.
SER,SFRBN and outcrossing rate(OR) of japonica CMS lines were investigated to analyze the relationship between them by using the DPS data processing system.
以583A、7740A7、7237A、春江12A、春江16A、春江26A、99-44A、宁67A、旱稻A等9个不同柱头外露率和花时的三系粳稻不育系为母本,以粳稻恢复系CH89为父本,进行大田小区制种,对不育系的午前花率、柱头外露率与异交结实率之间的关系进行了分析。
2.
The relationship between the anthesis time and pollinating time and outcrossing rate of the male sterile lines was studied with the parents as the materials in the hybrid rice seed production of Shanyou 63 (Zhenshan 97A×Minghui 63) and Shanyou 72 (Zhenshan 97A×Minghui 72) at two locations in 2001—2002.
2 0 0 1— 2 0 0 2年在 2个地点分别以杂交水稻汕优 63、汕优 72制种田的亲本为材料 ,对母本每天不同开花时段的颖花及受粉持续时间与异交结实率的关系进行了试验。
