ABSTRACT
Two year field experiment were conducted during kharif season of 2011-2012 and 2012-2013 at MCRS, NAU, Surat to determine GDD and HTU in inter and intra specific cotton hybrids and their respective parents. Nine cultivars, consisting of three inter and intra specific cotton hybrids viz. G.Cot.Hy-12, G.Cot.Hy-102 and G.Cot.DH-9 and their respective six parents were tested in randomized block design (RBD) with four replications. Cotton crop was sown on 08 July, 2011 and 07 July, 2012 during kharif season. Results revealted that amongst the three hybrids, desi hybrid G.Cot.DH-9 required maximum average GDD and HTU compare to other hybrids.
Key words :
