Abstract

Abstract: In order to evaluate the suitable sowing date of new wheat varieties Xinmai 69 in Xinyang city of Henan province, the effect of sowing date on the growth and yield components of wheat were studied with 10 sowing times. The results showed that, wheat leaf, tiller number, single stem fresh weight, single stem dry weight, plant height, spike grain number, filling rate, spike length and yield increased firstly and then decreased afterwards as sowing date delayed. The suitable sowing dates of Xinmai 69 in Xinyang were during October 25th to 30th.

Key words: wheat（Triticum aestivum L.）, Xinmai 69, sowing date, the growth period, yield components
