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 combining ability analysis was carried out in relation to GCA and SCA. Results were revealed that with regards to quality traits, PA 810 for UHML, PAIG. 380 for micronaire value & fibre strength and PA 811 for uniformity ratio found to be best general combiner for fibre quality traits. The cross PA 828 x Phule Dhanwantary had good specific combining ability effects for upper half mean length and fibre strength, PA 828 x JLA 794 for micronaire, whereas, G. Cot. 25 x AKA 7 for uniformity ratio.
