Abstract

Abstract: Wheat varieties with different ecotypes were studied in Zhengzhou for 4 years in succession. The plant morphological and ear developmental indices of varieties of different ecotypes were presented in the light of the developmental expression of varieties in 16 spring and autumn sowing times and the earring circumstances in spring sowing times. The leaf numbers of main stem are 12 for spring varieties sowed in autumn, 13 for semi-winter varieties, and 14 for winter varieties. The leaf ages at the begin growing period of main stem are 3 for spring varieties, about 4 for semi-winter varieties, and about 5 for winter varieties.

Key words: Ecotype, Wheat variety, Leaf numbers of main stem, Physiological jointing stage, Young ear development
