Genotypic Analysis of Heading Time on an Indica Rice Cultivar, Nanjing 11

<正> In this paper, the genotype of heading time in Nanjing 11, an indica variety, was analyzed by crossing with tester varieties, Akihikari (e1e1 e1e1 e3e3 SeleSele), Koshihikari (E1E1E2E2 e3e3 SeleSele), Nipponbare(E1E1 e2e2 e3e3 SelSel )and Hinohikari(E1E1 E2E2 e3e3 SelSel), of which the genotypes of heading time were well known. The results showed genotype of heading time in Nanjing 11 was E1E1 e2e2 E3E3 SelSel and also included a recessive inhibitor i-Sel for photoperiod-sensitivity as well. Meanwhile, the two
