DAHAT All India Co-Ordinated Cotton Improvement Project, Mahatma Phule Krishi Vidyapeeth, Rahuri, DistrictAhmednagar (M. S.) 413 722 India ABSTRACT : From the uptodate review of the literature on the aspect of polyploidy and its application in cotton breeding, it is concluded that the ployploidy resulting from chromosome doubling in natural diploid and amphidiploid species, both cultivated and wild, are generally sterile. Further, chromosome doubling in the sterile allotriploid hybrids of cultivated New World and cultivated Asiatic cottons results in fairly hexaploids which though not economically useful by themselves, can be of great indirect value for the synthesis of an allotetraploid of the genomic constitution of the New World cotton. The species relationship in Gossypium is much that in the buil...

The objective of the study was to evaluate the response and effect on estimates of phenotypic and genotypic correlation coefficients in G. arboreum cotton to variable intra row spacings of 67.5×10 cm, 67.5×20 cm and 67.5×30 cm having different plant densities. Correlations as well as direct effects of seed cotton yield with plant height were positive and high for averages of the two years in all the intra row spacings. In normal spacing of 67.5×30 cm significant and positive association of seed cotton yield were obtained for all the traits except boll weight. The results under three experiments of the spacing indicated that expression of association both at genotypic, phenotypic levels and direct effects were common for the traits plant height and boll weight in the thre...

Seed cotton yield showed positive correlation with all the component traits. The analysis confirmed that plant type with high boll weight, high number of bolls per plant and long fibres have high seed cotton yield.

The superior cultivars for absorbency were hybrid CICR 2 (1.0 sec) followed by CISA 17-93 (1.1 sec) and HD 432 (1.1 sec); for water holding capacity cultivars CISA 310 (28.1 g), HD 123 (27.3 g) and hybrid CICR 2 (27.1 g); for sinking time the cultivars were LD 694 (1.2 sec) followed by CISA 17-93 (1.3 sec) and hybrid CICR 2 (1.4 sec); for lowest ash content cultivars were AC 36-31(0.25 %) followed by LD 327 (0.28%) and CISA 6-256; for minimum water soluble substances cultivars were CISA-6-256 (0.26 g), RG 540 (0.27 g) and LD 327 (0.28 g). All the identified cultivars did not show any response with acidity/alkalinity. The yield was significantly higher in hybrid CICR 2 (35.2 qtl), CISA 17-93 (31.0 qtl) a...

An assessment of range of variability present in respect of various economic characters has been made. Promising germplasm lines with high yield (55 gm and above per plant), mean boll weight (4.00 gm and above), boll number per plant, monopods, sympods, ginning out turn (35.0% and above) and mean halo length (26 mm and above) have been listed. Fifteen germplasm lines combining moderate to high yields with other economic characters have.been identified which may be included in the hybridization programme of crop improvement. Two germplasm lines namely, MEX. 121 and 51.041 (V 1508) have outyielded for almost all the characters studied.

In G. hirsutum the range was for yield/plant 6.05-93.75 g, boll weight 2.1-3.75 g, boll number 1.75-33.5, ginning outturn 28.75-37. 95%, fibre length 24.3-28.4 cm, seed index 6.9-11.65, lint index, 3.43-6.5, sympodia/ plant 3.05-9.9. 3. Superior lines for yield/plant were 'K 3299', 'sort 3137' and 'Laxmi 7882'; for boll weight 'K 329', 'sort 3157'and 'ELS 103 (y) SN'; for boll number (up to 33.5) 'Membasa', 'K 3299 and Sort 5157'; for ginning outturn (up to 37.9 %) 'MEX 50 A (G)', 'Del Cot A' and 'ELS 134 W'; for lint index 'C 4B 58', 'ELS 134 W' and 'K 3299'; for seed index 'C 4B 5 8', 'Buri NL Naked' and 'Glandless'; for sympodia 'C 28', &...

The field experiments were conducted during these years of Kharif seasons on 27, 31, 32, 40, 40, 36, 39, 42, 42 and 45 genotypes in randomized complete block design with three replications at Central Institute for Cotton Research, Regional Station, Sirsa, Haryana. For a decade within all the years Genotypic coefficient of variation were found almost lower than the phenotypic coefficient of variation for all the traits viz., seed cotton yield, ginning outturn percent, lint yield, boll no. per plant and boll weight indicating preponderance of environmental variation over genotypic variation.

Five hundred and forty geographically and phenotypically diverse lines of G. arboreum L. were screened during 2001–2002 to 2003–2004. A wide range of variability for each parameter was observed. Eight lines PA 255, CISA 196, CISA 290, CISA 334, CISA 338, CISA 342, 6637 and AC 30&8 were completely resistant to shattering. The cultivar CISA 290 also showed higher boll number and good yield potential. Five superior genotypes for 2.5% span length (above 25.6 mm) were CISA 12 (27.5), DLSA 8 (26.8), PA 255 (26.5),1789 (26.4) and AK 580 (25.6); for fibre fineness CISA 12 (5.0), 1789 (4.9) AK 60-2 (4.8), AKH 607 (4.6), AK 580 (4.6) and 6629 (4.5); for fibre strength AC 3370-1 (24.8), KWAN 3 (24.5), CISA 245 (24.1), 6629 (23.2) AND PA 255 (22.7); for ginning outturn AKH 592 (37.3), DLSA 8 (35.5), AK 580 (35.0), 6571 (35.0) and KWA...
