Abstract:
The Line x Tester method of analysis was followed involving seven female lines viz., PA 810, PA 828, PA 837, PA 811, PAIG 380, G. Cot. 25 and G. Cot. 17 for study of heterosis for various fibre quality characters at three environments viz., Parbhani, Nanded & Badnapur. The F₁ and their parents were evaluated in randomized block design with three replications, observations were recorded on Fibre length (mm), Micronaire (µg/inch), Uniformity ratio (%) and Fibre strength (g/tex). The magnitude of heterosis was estimated in relation to better parent and standard checks. Results revealed that the cross combination PA 828 x Phule dhanwantary showed the highest and desirable significant standard heterosis for UHML, PAIG 380 x JLA 505 for micronaire value, whereas, the cross PA 837 x PA 08 and PAIG 380 x PA 08 for uniformity ratio and PA 811 x JLA 794 for fibre strength and also exhibited high percentage of heterobeltiosis and high per se performance.
