Correlation between quantitative traits and grain productivity of the waxy maize hybrids
نویسندگان
چکیده
A subspecies of waxy maize (Zea mays L. ceratina) is characterized by the fact that its grain contains 100 % amylopectin starch, a valuable raw material for confectionery production, manufacture polymers, and blood substitute. The absence domestic hybrids in State List Breeding Achievements necessitates study this area breeding. purpose current was to identify dependencies make it possible increase efficiency breeding process when developing hybrids. carried out at FSBSI “ARC “Donskoy” 2020–2022. objects were 36 developed method interline hybridization. studied traits differed degree variation. High coefficients variation identified ‘grain productivity’ (V = 30.1 %) ‘one cob weight’ 21.5 %). ‘number rows’ 8.4 yield during threshing’ 8.2 turned be slightly varying. An values any trait resulted an yield. However, signs productivity not equivalent according their effect on formation There have been most influential productivity, such as cobs per 1 plant’, seeds cob’. correlation between them positive, close (r 0.73±0.12 – 0.82±0.10). positively associated with rest 0.30±0.16 0.74±0.12), selection samples high does reduce other traits. must taken into account selecting initial

Effect of fertilizer management and the application of zeolite on agronomic traits and grain yield of maize (Zea mays L.) hybrids under deficit irrigation conditions
Drought stress is considered as the most important limiting factor for growing of crops such as maize. Under low irrigation conditions, proper nutrition of plants can improve the effects of drought stress. This experiment was carried out in order to investigate the effect of nutrition management along with application of zeolite on agronomic traits of two hybrids of maize under deficit irrigati...
متن کاملon translation of phatic communion and socio-cultural relationships between the characters of the novels
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
