Thirteen genetically diverse parents collected from the different parts of the country and their 36 crosses generated by using line x tester mating design, was undertaken to study the heterosis and heterobeltiosis for fruits yield and its contributing characters in okra. Majority of the hybrids exhibited significant and positive heterosis over mid-parental value and over better parent for most of the traits. Seventeen hybrids showed significant and positive heterobeltiosis for fruit yield per plant. The cross combination Parbhani Kranti x D-1-87-5 exhibited the highest heterobeltiosis (184.27%) for fruit yield per plant. Manifestation of heterosis by this particular cross combination was also realized for all the characters except for days to flowering and number of nodes per plant. The heterosis over better parent for yield per plant was mainly due to longer and thicker fruits coupled with more number of fruits per plant.Keywords

Investigation was carried-out to assess the selection indices in 40 genotypes of wheat (Triticum aestivum L.) in limited irrigation under late sowing condition. Sixty-three selection indices, involving grain yield per plant and five yield components, were constructed using the discriminant function technique. The efficiency of selection increased with the inclusion of more number of characters in the index. The selection index based on six characters viz., grain yield per plant, days to maturity, number of productive tillers per plant, number of grain per main spike, biological yield per plant and harvest index under limited irrigated condition exhibited maximum gain and relative efficiency. It is expected that grain yield could be improved if due consideration is given to these traits in future breeding programme of wheat.Keywords
