过去由于温饱问题还比较突出,在评价品系时,把注意力较多地集中在稻谷产量的高低上。凡是比对照品种增产达到显著或极显著标准的,容易通过区试和审定关。稻谷产量水平的高低,是评价参试品系很重要的一项指标,但不应该是唯一的,其它性状也应该予以考虑。否则,评价是不全面的,在评价参试品系时,应该将稻谷产量、稳产性、抗逆性、外观品质等综合性状进行全面分析,并预测其社会效益和经济效益,客观地作出评价。
In the past, due to the fact that the problem of adequate food and clothing was still outstanding, we focused our attention more on the level of paddy production when evaluating lines. All varieties than the control yield increase reached significant or very significant standard, easy to pass the district test and examination of customs clearance. The level of rice yield is a very important indicator for evaluating the tested lines, but it should not be the only one. Other traits should also be considered. Otherwise, the evaluation is not comprehensive. When evaluating the tested lines, the comprehensive traits such as grain yield, stability, resistance and appearance quality should be comprehensively analyzed, and the social and economic benefits should be predicted. The objective evaluation should be made.
