早杂生产是我市粮食增产的重要一环,由于近年本市种植的早杂组合如汕优48—2,威优402,K优402等存在熟期偏长或米质偏差等缺点,使我市早杂种植面积始终徘徊在早稻总面积的20%左右,严重影响早稻的持续增产。因此,选育熟期早、抗病力强、米质较优、产量高的早杂新组合成为当务之急。为了加速选育进程,我们选择了云南省元江县基地进行异地秋繁。 As early as miscellaneous grains production is an important part of grain production in the city due to the early hybrids planted in recent years, such as Shanyou 48-2, Weiyou 402, K You 402, etc. There are shortcomings such as the length of cooked or rice quality deviation, so that Early hybrid rice planting area in our city has always hovered around 20% of the total area of ​​early rice, seriously affecting the continuous increase of early rice. Therefore, breeding early maturity, disease resistance, better quality, high yield of early hybrids become a top priority. In order to speed up the breeding process, we have chosen Yunnan Yuanjiang County base for off-site autumn Fan.
