FLORAL BIOLOGY IN COTTON1. Varies from species to species 2. Calyx –5.3. Petals-5.4. Stamens numerous.

Four cultivated species1- G. hirsutum2- G . arboreum3- G . barbadense4- G . herbaseum

1.To study the heterosis and combining ability of new cotton hybrids in respect of seed cotton yield and its attributing characters.

2.To study the type of gene action in the control of above traits.

3. To study the association, direct and indirect effects of component characters on kapasyield .

Heterosis

Combining ability analysis

Correlation studies

Path coefficient analysis

The experimental material used in the present study comprised of

fourty eight experimental hybrids of cotton (G. hirsutum.L.) received

from Sr. Cotton Breeder, ARS, Hebballi farm, Dharwad along with

three released hybrid as checks .

Experimental material

These hybrids were produced by crossing six female lines with

eight male testers.

The present investigation in cotton was taken up during kharif

2008 at Agricultural Research Station, Bavikere, UAS.

STATISTICAL ANALYSIS

1. Analysis of variance - ( Panse and Sukhatme, 1967)

2. ANOVA for combining ability analysis - ( Kempthrome, 1957)

3. Estimation of variances - (Singh and Chowdhary ,1985)

4. Estimation of combining ability effects - (Kempthrome, 1957)

5. Overall status of a parent and cross with respect to gca and sca

- Arunachalam and Bandyopadhyay (1979) concept that was slightly modified

by Mohan Rao (2001).

6. Estimation of heterosis - Turner (1953) and Hayes et al. (1955)

7. Test of significance for heterosis - Arunachalam (1976)

8. verall status of a parent and cross with respect to gca and sca and

heterosis Arunachalam and Bandyopadhyay (1979) concept that was

slightly modified by Mohan Rao (2001).

Future line of work

1- The performance of two top hybrids viz., 133, 134 in respect of kapas yield needs to be verified performance on large scale basis.

2- The results implies that one line and four testersstudied were high combiners across all the traits, indicating their ability in transmitting additive genes in the desirable direction to their progenies. Further, these lines and testers can be tested for the confirmation of their superiority as good parents for hybridization
