dc.description.abstract | Two crop specific explorations were conducted in arid, semi-arid and sub-humid areas of Rajasthan and Gujarat resulting in 182 collections from target variability pockets and areas of commercial chili cultivation. Besides, 18 landraces collected from 10 districts of Gujarat by GAU, Vejalpur and 10 lines of Guntur type chilies from Lam (Andhra Pradesh) were also assembled. Thus, total 210 chili genotypes were evaluated from 1999 to 2002 under hot arid agro climatic conditions at CIAH, Bikaner for agro morphological growth, flowering and fruiting behavior, fruit yield and quality contributing characters, and also to screen the material against biotic and biotic stresses. The survey studies revealed that a large number of varieties and types of chilies are under cultivation and perhaps these have been developed by natural selection, long period of cultivation under varying climatic conditions and hybridization. Based on fruit size and shape, seed content and pungency, some popular types and selections are well known, e.g., Mathania, Haripur-Raipur, Mehsana, Nikhari, Patodl, Tonk Local, Mahaveerji Local and some desi types. In the past few years, however, due to several factors such as high incidence of viral diseases and unavailability of good quality and pure seeds of desired types, there is drastic reduction in yield potential even in some popular types like Mathania Local. One of the approaches is phenotypic selection from the available variability. The Success of phenotypic selection in a breeding programme, however, depends upon the range of genetic diversity available in the population and also on its information on the heritability of plant characters and association among yield and its component characters. The results of evaluation and categorization of the collected germplasm revealed that, in general, there are well known pockets/areas where some typical types of land races or local cultivars of chili are still being cultivated on large scale and maintained by the growers owing to its peculiar quality and market demand. Due to one or more production factors, the yield potential of these landraces is low and even then its Cultivation is continuing. These are Mathania type chili in Jodhpur, Nagour and Jalore; Mahaveerji Local in Karoli and Swaimadhopur; Patodi and Nikhari in Tejara (Alwar) and Tonk Local in Tonk districts of Rajasthan. Besides, there are very peculiar types or landraces locally known as desi of the particular areas have distinct quality components and liked by a group of community. In tribal areas, still farmers are being maintaining the local land races for their domestic purposes possessing unique fruit quality, small size and high in pungency. By and large, on the basis of fruit quality and market demand, the local land races/ types of Mathania, Mahaveerji, Tejara (Alwar) and Tonk could be further exploited to develop uniform fruit producing genotypes with consistence yield potential. The chili genotypes were characterized for more than 45 traits. However, the studies on analysis of variance for nine important quantitative characters revealed that the mean squares were highly significant for all the nine characters indicating considerable variability in the genotypes. The range, mean and genetic variability components are presentation Table 2. The estimates of PCV and GCV exhibited almost similar trend of variability. The extent of coefficient of variation indicates that fruit yield per plant, number of' fruits/plant, fruit weight, number of seeds/fruit, fruit length and fruit diameter had maximum PCV indicating better scope of phenotypic selection to enhance the fruit yield in chili. Genetic advance as percentage of mean ranged from 13.47 to 185.64 per cent. Thus, there is a tremendous scope to isolate superior genotypes for improving yield through simple selection procedures. | en_US |
