India is the second largest fruit-producing country in the world. A number of problems including diseases, insects, pests and various disorders are associated with fruit growing in India these problems can solve by utilising of Plant genetic resources. Inferior quality of planting material and poor orchard management are some of the reasons for the low productivity.

गेहूँ में पूर्व-प्रजनन: संभावनाएं एवं चुनौतियां Pre‐breeding refers to all the activities designed to identify desirable characteristics and/or genes from un-adapted materials that cannot be used directly in breeding populations and to transfer these traits to an intermediate set of materials that breeders can use further in developing new varieties. Crop wild relatives have a high level of genetic diversity with rare alleles that enabled them to survive in natural and adverse environments. Most plant breeders fear in using exotic or un-adapted material due to its initial detrimental effects like linkage drag on elite breeding material. It is a necessary first step in the use of diversity arising from wild relatives and...
