Tillering and earbearing characteristics of wheat varit ies “ miannong 4 " and “ miannon 3 " were studied under three densities. the results indicated that t he two varieties had medium tillering speeds and tillering numbers , and their t illering number under medium density was 3. 7 tillers per plant , which is less th a n that of “ mianyang 11 " , a popular wheat variety in sichuan in 1980s. their perc en tage of earbearing was about 55 % , which is also lower than that of “ mianyang 11 "
