【Abstract】 Changes in growth and development of cotton associated with nectarilessgenes were measured at two locations in Wuhan in 1984. Near-isogenic linesused were developed in two genetic backgrounds through backcrossing(3 times)and selfing (4 times) programs. The number of squares, bolls and sheddingswas counted during its growth season. The results showed that the growthpattern of nectariless plants was similar to that of its normal plants.更多还原
