Assessing the regression of characters in shoot induction Of potatoes (Agrian cultivar)

Behnam1 Morteza2

Abstract :
Abstract: To evaluate the effect of six combined hormones and vitamins as treatments on some of traits in potatoes cultivar (Agria), an experiment was conducted in 2014-2015 in a randomized complete block design with three replications in laboratory condition. Linear and quadratic regression analysis showed that between the two evaluated traits (y = main shoot length, x = number of secondary shoot) there was a significant relationship as follows: y=75/278-2/087x and y=76/546-2/699x+0/061x2. The above equation shows that by increasing the number of secondary shoot, main shoot length decreases. Linear and third degree regression analysis showed that between the two evaluated traits (y = the maximum of secondary shoot length, x = number of secondary shoot) there was a significant relationship as follows: y=11/621-0/571x and y=4/179+5/816x-1/295x2-0/074x3.The above equation shows that by increasing the number of secondary shoot, the maximum of secondary shoot length decreases. Quadratic regression analysis showed that between the two evaluated traits (y = the maximum of secondary shoot length, x = number of secondary shoot) there is no significant relationship as follows: y=8/307+1/028x-0/159x2. The above results show that by increasing the number of secondary shoot, the maximum of secondary shoot length may be increased or reduced. Linear and quadratic regression analysis showed that there was a significant relationship between the two traits evaluated (y = the minimum of secondary shoot length, x = number of secondary shoot) as follows: y = 8 / 844-0 / 774x and y=7/041+0/096x-0/086x2. Above relationship shows that by increasing the number of secondary shoot, the minimum of secondary shoot length decreases. Based on regression analysis between the third grade of two traits showed that (y = the minimum of secondary shoot length, x = number of secondary shoot) there was a significant relationship between them (y=2/791+5/025x-1/256x2-0/076x3). Linear and quadratic regression analysis showed that between the two evaluated traits (y = the mean of secondary shoot length, x = number of secondary shoot) there was a significant relationship as follows: y=10/781-0/786x, y=8/383+0/3714x-0/115x2. The above equation shows that by increasing the number of secondary shoot, the mean of secondary shoot length decreases. Quadratic regression between the two above traits was significant at 1 % (y=4/126+5/306x-1/286x2-0/076x3). The results showed that among the two traits mean secondary shoot length and number of secondary shoot first, second, and third grade regressions, was significant at 1% level.
