Genetic Diversity in Relation to Fodder Yield and its Components in Sorghum

Indian Journal of Genetics and Plant Breeding (The) (1971)

P. D. Mehndiratta P. S. Phul N. D. Arora

Thirty varieties of Sorghum comprising indigenous and exotic material were subjected to multivariate analysis with a view to study divergence among them. Out of the five characters studied, viz., plant height, stem girth, number of leaves, length of leaf and fodder yield, length of leaf and fodder yield were found to be the major contributors towards divergence in the material. On the basis of Mahalanobis's D2 values, the thirty varieties were grouped in seven clusters. In general, geographic diversity was not found to be related to genetic diversity. However, some of the varieties belonging to common origin were grouped together in the same cluster. Highly divergent stocks isolated on the basis of this analysis can be successfully exploited in breeding programmes aimed at the evolution of high yielding fodder strains.

STUDY OF COMBINING ABILITY AND GENETIC PARAMETERS FOR YIELD AND ITS COMPONENTS IN WHEAT

The Japanese Journal of Genetics (1969)

K. B. Singh Devendra Kumar Sharma P. D. Mehndiratta

A set of seven wheat varieties from two different ecogeographical origins were studied in a diallel cross to find out the combining ability and the genetic parameters for yield and its components. The general and specific combining ability estimates for spike number per plant, spikelets per spike and seed size indicated predominance of additive gene effects, while for yield the variance for general and specific combining ability were of same order, suggesting importance of additive as well as non-additive effects. Per se performance of the varieties was in close agreement with the general combining ability estimate.The Vr-Wr and Wr-W' graphs showed overdominance for spikes per plant, spikelets per spike, 100-kernel weight and grain yield. In general the predictions regarding the parents made from general and specific combining abilities are in line with gene action indicated by the Vr-Wr and Wr-W' graphs for different characters.Implications of the genetic parameters on breeding approach in wheat have been discussed.

Path analysis and selection indices for cowpea.

Indian Journal of Genetics and Plant Breeding (The) (1970)

K. B. Singh P. D. Mehndiratta

Path coefficient and selection indices were studied in 40 lines of cowpea in a randomized block design with three replications at Punjab Agricultural University, Ludhiana, during 1967. Pods per plant, grains per pod and 100-grain weight had appreciable direct effect on grain yield. Multiple regression analysis suggested that grains per pod, 100-grain weight and pods per plant were the important yield components and together account for about 68% variation in yield. A discriminant function based on two yield components, grains per pod and 100-grain weight, and the three yield components, grains per pod, 100-grain weight and pods per plant, was found to be superior to selection for yield to the extent of 24 and 33%, respectively.

Genetic variability, correlations and path analysis of fodder yield and its components in Sorghum

P. S. Phul N. D. Arora P. D. Mehndiratta

Of seven characters studied in 30 varieties, fodder yield showed the highest genetic coefficient of variability and, with number of days to flowering, the highest estimates of heritability in the broad sense. Heritability estimates for stem girth and the number, length and breadth of leaves were lower than those for fodder yield, indicating limited scope for improvement by selection. Fodder yield was significantly and positively correlated with the latter four characters, both phenotypically and genotypically and these four characters were also correlated with one another. Path-coefficient analysis indicated that length and breadth of leaf, and stem girth contribute most to fodder yield.

Nutritive value of newly developed forage bajra composite in buffalo calves

Indian Journal of Animal Nutrition (2001)

A. K. Ahuja B. K. Gupta P. D. Mehndiratta

A newly developed forage-bajra composite (Cv. FBC-16) contained comparable protein (9.20%) and lower cell wall (61.70%) and oxalate (1.82%) contents than the existing variety PBC-141. The digestibility of proximate principles was also higher in FBC-16 than that in PCB-141 in buffalo calves. The voluntary DMI (kg/d) and effective degradability (%) values for FBC-16 and PBC-141 were 3.99 and 44.8 and 3.66 and 44.5,respectively. The newly developed variety FBC-16 showed an edge over existing variety PBC-141 in terms of DCP, TDN and DM degradation rate. In fodder production, FBC-16 surpassed PCB-141 by a margin of 32.2%.
