crossability การใช้

• Crossability of distant hybridization between o . sativa and o . glaberrima
• Seventy - nine improved wheat cultivars ( lines ) including some related parents were corssed with rye to detect the difference of crossability among wheat genotypes and the developing tendency of crossability during the cultivar renewing period in shandong province , the results expressed that crossability of improved cultivars with rye were significantly lower than that of the check ( chinese spring ) , and there were 3 cultivars with a seedset of more than 50 % , 4 cultivars with the seed - set of 30 % - 50 % , 8 ones with that of 10 % - 30 % , 50 ones with the seed - set of less than 5 % , and the other 14 cultivars with the seed - set of 5 % - 10 % ; the mean crossability between wheat and rye decreased with the renewing of cultivars in shandong , and the number of cultivars with the seed - set of more than 50 % and 30 % - 50 % also decreased , but that with the seed - set of less than 5 % increased gradually during the renewing period ; pedigree analysis revealed that the crossable gene of the tested cultivars might come from 3 landraces ( youzimai , mazhamai and huixianhong ) , laizhou 953 , 8641012 , yannong 15 et al were improved wheat cultivars with both excellent agronomic traits and high crossability with rye
