  hybrid rice variety
Efficiency of mixed and compound fertilizers containing ammonium and nitrate forms on a new hybrid rice variety.
      
One of the downfalls of CMS line hybrids is the amount of time and effort it takes to make a successful hybrid rice variety this way.
      


Years after cultivation, the hybrid combinations Shanyou No.2 and Siyou No.2 were gradually losing their resistance to blast because their restorer line IR24 was susceptible. In order to solve this probelm.a new restorer line Minghui 63 was produced by crossing IR 30 and Gui 630; Shanyou 63 by crossing restorer line Minghui 63 and ms line Zhenshan 97A.

Years after cultivation, the hybrid combinations Shanyou No.2 and Siyou No.2 were gradually losing their resistance to blast because their restorer line IR24 was susceptible. In order to solve this probelm.a new restorer line Minghui 63 was produced by crossing IR 30 and Gui 630; Shanyou 63 by crossing restorer line Minghui 63 and ms line Zhenshan 97A. Reasults showed that this combination was marked by higher yield, better grain quality, more resistance to blast and extensive adaptability.It had extended rapidly, ranking first on the list in the planting area. In 1986 it covered 2. 26 million hectares in the south of China. Between 1982 and 1985, it usually took the lead in area whether in the country or in local districts; the average yield from 1982-1985 was 7.2T/ ha, increasing by 1.02T/ha or 16.1% as compared with the check combinations Shanyou No.2 and Shanyou No.6. It is estimated that the total yield increased by 1986 amounted 2.89 million tons. This combination was especially fit to grow as a medium variety because its growth period lasts 4-5 days longer than that of Shanyou No.2. If it is used as a late variety in the double cropping system, the sowing date should be taken into considerations in order to avoid the autumn cool. It is estimated that this combination will exten its planting area in the south of China and develop its social efficiency. And the other new combinations with the restorer line Minghui 63 are being experimented with and are under development.

明恢63是用IR30与圭630杂交育成的。汕优63是珍汕97不育系与明恢63配组育成的杂交水稻新组合。它具有高产、优质、抗瘟和适应性广等优点,成为全国杂交水稻中主要的当家组合。1982~1985年参加全国、省、市三级区试,多居首位。平均亩产482.0公斤,比对照组合(汕优2号、6号等)平均亩增68.0公斤,增产16.15%。三年(1983~1985年)来在南方稻区各省推广近千万亩,1986年达3500万亩。1985年全国推广1000万亩估计增产稻谷6.5亿公斤,其社会经济效益将超过1.5亿元。根据栽培技术研究和大面积生产示范实践证明,汕优63仍有很大潜力,抓好良种良法,可达到更高的产量,取得更显著的经济效益。

This study analysed the yield stability of new hybrids of rice throgh the data from cultivar regional tests in 1987. The results showed as follows: 1. The yield and yield stabity of Dyou 10 are the best in the regional tests. 2. The correlation coefficent between mean yield and regression coefficient bi were nonsignificant) r_x. bi=0.293). 3. The hybrid yield stability was associated with the harmony of main characters changes to a series of enviroments.

杂交水稻新组合的区试资料进行了初步分析,认为1、D优10号丰产性好、适应性强;2.杂交水稻产量与其稳定性参数bi间相关性不显著(V·bi=0.293);3.杂交水稻产量的稳定性似与其有效穗数相关联,且可能与其主要农艺性状在不同环境条件下变化的协调性有关。

The flowering habits of the parents of Shanyouguang 12, i.e. Guang 12, the restorer, and Zhenshan 97A, the sterile line, were observed. The flowering time of Guang 12 ranges from 9:00 a. m. to 13:00 p. m., the blooming period from 10:00 to 12:00 a. m., the peak is at 11:00 a. m. The flowering duration for each plant lasts for 13 days. The flowering time of Zhenshan 97A is diffused. The synchronization of the parents' flowering time happens from 9:00 a. m. to 13: 00 p. m. every day. If the parents' flowering...

The flowering habits of the parents of Shanyouguang 12, i.e. Guang 12, the restorer, and Zhenshan 97A, the sterile line, were observed. The flowering time of Guang 12 ranges from 9:00 a. m. to 13:00 p. m., the blooming period from 10:00 to 12:00 a. m., the peak is at 11:00 a. m. The flowering duration for each plant lasts for 13 days. The flowering time of Zhenshan 97A is diffused. The synchronization of the parents' flowering time happens from 9:00 a. m. to 13: 00 p. m. every day. If the parents' flowering time fully synchronizes, the setting percentage can be 45.88% for early season, 43.75% for late season. A 20% of setting percentage can be recorded even though the flowering time of the parents is 48 hours apart while pollination.

杂交水稻新组合汕优广12的父本广12,花时在9~13时,盛花在10~12时,峰值出现在11时,单株花期长达13天。母本珍汕97A花时分散。制种花时相遇在每天9~13时,集中在11~12时。花时全遇时,结实率早造达45.88%,晚造达43.75%。花时相隔48小时授粉,结实率仍可达20%。这一特征,为制种夺高产提供了生物学依据。
